Hire Ruby on Rails developers

As a backend developer with a strong foundation in both science and technology, I offer a unique combination of academic research experience and hands-on software engineering expertise. I hold a master’s degree from the Moscow Institute of Physics and Technology and spent seven years at the Institute for Nuclear Research in Troitsk, contributing to the Baikal Neutrino Telescope project. This background sharpened my analytical thinking and problem-solving skills in high-complexity environments. Alongside my research, I built a solid foundation in software development, working with C++, PHP, and bash. Eventually, I transitioned fully into tech, taking on roles as a Network and Software Engineer before progressing to Senior Software Engineer and Team Lead positions at Qlean. I’m currently based in Berlin, Germany, working as a Senior Backend Developer at Handshake. My primary language is Ruby, but I’m also interested in Golang, Rust, and Elixir. I thrive on solving complex technical challenges, writing clean and scalable code, and continuously learning new systems, algorithms, and techniques. At the same time, I understand the importance of balancing technical ideals with business realities — sometimes, delivering a valuable feature on time is more important than writing perfect code. Looking ahead, I’m excited to connect with like-minded professionals, explore new challenges, and continue building reliable, impactful software.

I bring the speed and autonomy of an indie hacker with the technical discipline of a team player. My journey started with a simple goal — solve problems I faced myself. That grew into launching my own SaaS products, self-hosting automation tools, and running a solo product studio (Pixxmo) — where I wear every hat from backend dev to marketer. What makes me stand out is that I don’t just build features - I build solutions with business context. I’ve shipped full products solo using Next.js, Supabase, Prisma, and AI tools like DeepSeek and Llama. I understand performance, scalability, clean architecture, and also the human side of software - what users want and how to deliver it fast. If you’re looking for someone who can plug into your team, adapt fast, and deliver value from day one - I’m that developer.

🟥 Over the past five years, I’ve built interactive and scalable applications with Angular, SCSS, and modern JavaScript, while more recently expanding into Ruby on Rails. One recent milestone was contributing to full-stack legal tech features, where I combined API design, secure workflows, and UI integration. This mix of frontend depth and growing backend expertise allows me to approach problems holistically and deliver features that fit seamlessly into real-world products. 🟥 I’m passionate about creating intuitive user experiences and mentoring others. As a volunteer technical lead on a cross-platform fashion app, I not only built with Angular and Flutter but also guided junior developers through code reviews and architectural decisions. Community matters to me, and I regularly mentor beginners through Codebar, helping others take their first steps into coding. 🟥 Based in the UK, I focus on remote-first roles, since opportunities are limited in my local area. I am open to monthly meetups in cities such as London, Birmingham, Edinburgh, or Bristol, provided travel time and transport are factored in. I am also actively learning German and would be happy to travel to Berlin if required, as part of being proactive in my professional growth and cultural learning. 🟥 What makes me unique is the blend of adaptability and breadth: I’ve worked across frontend, backend, mobile, and product strategy, and I thrive in collaborative environments where I can connect the dots between design, engineering, and business needs. I bring not just coding ability, but also the empathy and perspective to help teams ship meaningful digital products.

Here’s a peek at what I can do: • Full-stack Dev across REST, GraphQL, and Decentralised Architectures • Deep experience with Ruby and TypeScript • Bonus: I hold a minor degree in Human-Computer Interactions!

Through my agency at invokestudio.io, I have helped several companies implement new features, prototype MVPs, build greenfield apps, clean up technical debt, and standardize the codebase. I am experienced with the full-stack and can also contribute with DevOps (backend) and UI (frontend) implementations. I am an open-source contributor and core member of Bridgetown. Some exciting passion projects I am currently building include a React CMS for Bridgetown, a ViewComponent library for Rails, and an online listing marketplace for my region at centralcoastclassifieds.com. I maintain a tech blog at mugenruby.com and cross-post articles on other blog sites. SKILLS Soft: I’m a great listener and communicator, empathetic towards the users of products I build, organized, adapt quickly to change and manage my time well. Hard: HTML/CSS, JavaScript/StimulusJS/React, Ruby/Rails, ActiveRecord/SQL, Git, AWS S3/SES, Email service providers, Relational data modeling, REST, RSpec/MiniTest, Error Monitoring/debugging, building/implementing APIs and webhooks, Redis, ElasticSearch, Stripe Connect. Projects I have done Built a peer-to-peer marketplace that allows users to search for items to rent from sellers. Sellers are required to connect a bank account via Stripe Connect before being able to create listings. ActionCable-powered chat feature with email reminders and read receipts Location-based searching with Searchkick and Opensearch (ElasticSearch equivalent) Calendar style booking system with confirmation settings and payment system Created an online application process to collect information from applicants looking to join a real estate listing service. Applicants are prompted to pay online, receive status emails, and digitally sign documents. Staff users can manage applications via filtering, updating the status of the application to denote its stage in the process, request payments and signatures, and create events links that are populated and sent out via email. PDF generated with data from the applications filled by users. Generation of PDF triggers actions that involve callbacks, API calls, and emailing users, and ability to download signed PDF via email or UI. Various API calls and listening for web hooks during the digital signing process via Docuseal’s service. Involves uploading pre-filled PDF as a template, calling it again when requested for signature, and listening for an event to indicate it was completed. Stripe Checkout integration with custom line items, redirects, and object instantiation upon successful payments. Built a questionnaire builder that allowed users to create questions organized by custom surveys. Referenced existing Figma screens and translated the user flow into code. Hotwired-heavy frontend with use of Turbo Frames and Turbo Streams. Use of StimuluJS for dynamically adding/removing question fields, tabs, and modals. Designed the data model relations from ground up.

Kent Beck recently said: “AI has reduced the value of 90% of what I do to zero, but the other 10% has gone up by 1000x.” So what’s in that “other 10%”? It’s the part non-engineers rarely appreciate — because they don’t see it firsthand: • Debugability • Introspection • Solid structure • High-quality tests Let’s be honest: debugability in AI-generated code is a disaster. We’re witnessing a flood of code written by non-engineers — vibe coders — that seems fine until it explodes months later. That’s when the real nightmares begin: bugs that require eight steps across different actors, cause baffling side effects in unrelated parts of the app, and defy every attempt at consistent reproduction. They’re unfixable, unscoped, and they never die. Introspection — the ability to look clearly into your code, your data, your stack — is an art. And as far as I can tell, AI isn’t introspecting. So it doesn’t care if your data is obscured or lost behind poorly constructed abstractions. But you should care. Solid architecture should be non-negotiable by now. Yet somehow, we still see apps with business logic scattered across layers, leaky abstractions, and no internal consistency. We once thought these lessons would become table stakes. They haven’t. And then there are tests. What counts as a high-quality test? In my paper, “Automated Tests from 10,000 Feet,” I explore how effective testing is about intent and confidence. In healthy codebases, tests are written with the code — not bolted on later. But for decades, computer science programs have overemphasized unit testing, neglecting system testing. Now we have a generation rebelling against tests altogether, many of them openly hostile to the practice. Why? Because we failed to demonstrate the real value of tests. Unit tests rarely catch regressions. But a lean, strategic suite of high-quality system tests? That’s pure gold. That’s what gives you the confidence to refactor, to ship, to move fast without breaking everything. It’s time for a course correction. Are you building something that needs a founding engineer? I’m looking for 50% equity, with a $0 salary. If you're serious, let’s talk.

I'm a full-stack developer passionate about building scalable, secure web applications that solve real-world problems. With a strong foundation in Python/Django and Ruby on Rails, I've delivered high-impact systems for government, logistics, and healthcare—most recently developing a secure logistics platform for Kenya’s Ministry of Defense. I’ve modernized legacy infrastructures using React, Node.js, and AWS, and contributed to AI research at Scale AI by refining code generated by large language models. I care deeply about clean code, performance, and delivering solutions that drive efficiency and growth. Let’s build something that matters.

Curious, thoughtful, and resourceful software developer with a passion for backend engineering and a specialization in Ruby on Rails. I have thrived on exploration, continuous learning, and embracing new experiences, both in the tech industry and beyond. My origin story began with a diverse range of experiences, from working in conservation at the Grand Canyon to teaching in Japan and higher education in Colorado. However, it was a conversation over coffee that introduced me to the world of coding and sparked my interest in solving problems with Ruby. For 2 years at Measurabl, I have taken my enthusiasm for exploration, growth, and effective communication into developing and maintaining a high-volume REST API. This RoR application consumes multiple external and internal data sources to provide environmental (ESG) data for the real estate sector. In my current position, I develop Rails back end and front end micro-services to serve credentialing data on health care providers. I am a proactive and supportive teammate. I love brainstorming, pair/mob programming, and am always willing to present new features on behalf of the team. I can't wait to leverage my skills and experiences to contribute to a dynamic and collaborative team. Let's connect!

I pride myself on being self-motivated and committed to delivering exceptional work. My passion lies in making a positive impact on people's lives through the software I develop. In my last 3 years, I have gained valuable experience in developing and implementing financial systems that significantly impact small and economically disadvantaged countries. One such notable experience involves designing and integrating a financial system between nations in Asia to streamline and expedite bank transactions. This project presented unique challenges, as it required a deep understanding of the financial landscape and regulatory of countries. I am used to working closely with stakeholders and experts from the banking sector, I collaborated to develop a robust and secure platform that facilitated seamless transactions and improved overall efficiency. The success of this project not only transformed the way banking was conducted within these nations but also improved their economic and social values. We provide a fast and easy-to-use financial system, for both usage individuals and businesses. Nowadays I am learning Go and Rust to improve my DevOps capabilities.
