Versatile fullstack dev, loves writing tests and following TDD.

Recently updated

8+ Years of experience | Ruby on Rails specialist | Passionate about testing I've studied electronic engineering, specialty in computer science and sub specialty in physics. I am a self-taught full stack developer. I've learned to code on QBasic when I was a kid, at the end of the 90's, and I've been working in software development since 2014, most of the time working in Ruby on Rails, the sum adds 8+ years of experience in RoR. Since the first time I've started working with Rails I've worked following a TDD approach. My experience tells me that's the best way to avoid bugs. I've used RSpec all along my journey. My latest discovery is the best way to enrich my vocabulary in any programming language is by reading other people's code. That's the reason why I'm hunting issues in github, I've made several contributions to many different open source projects. My last PR is a fix for RSpec::Support::Differ class: I've found a bug when you compare two different hash objects and the expected value contains an "anything" fuzzy matcher, it adds noise to the output of the differ. My PR fixes that issue: https://github.com/rspec/rspec-support/pull/599 I have noticed the web is always consuming more and more memory ram. That's the reason why I've focused my efforts on my previous jobs to optimize slow web pages and optimize as much SQL as I can. I helped my last client to reduce in half the memory ram consumption measured on his Heroku metrics. These optimizations helped him to save money on Heroku. I am learning Rust and I have built many tools like rg_explorer to help me find what I need in big projects. I want to become proficient in Rust because I have hope in the future WASM may become something common in webapps, because I think that may be a good candidate to reduce the amount of memory ram consumed by web browsers. I am a versatile software engineer because I've used many programming languages in the past: Python, Rust, Node.js (including React.js and Vue.js). I have found many of the activities mentioned above are really boring for many people. It's odd that I enjoy doing them so much. That's why I think I like to do boring stuff...

Hi! I’m Aditya Jain, a backend engineer with 7+ years of experience in Ruby on Rails. I’ve worked on SaaS platforms, built scalable APIs, and integrated complex systems. I’m joining ruby.social to stay connected with the Ruby community, share knowledge, and learn from others working with Rails and backend technologies. Looking forward to engaging discussions!

New profile

I'm Aditya Jain, a backend engineer with over 7 years of experience, primarily building scalable, secure applications in Ruby on Rails. My journey began in electrical engineering, but I quickly pivoted into software development when I realized how much I enjoyed solving logical problems and bringing ideas to life through code. Rails, with its elegance and convention-over-configuration philosophy, instantly clicked with me—and I never looked back. One of my recent milestones was leading the architecture revamp of a high-traffic Rails-based payments system, optimizing performance under load and ensuring PCI compliance. This not only improved p95 latency by 45% but also reinforced my belief that solid engineering is about thoughtful design, not just writing code that works. What sets me apart is my ability to blend technical depth with business understanding. I don’t just deliver features—I ask why they matter, who they impact, and how we can deliver them better. I’ve led small teams, handled enterprise client integrations, and even driven analytics efforts using tools like ClickHouse. I also enjoy mentoring junior developers and fostering a clean, test-driven development culture. I’m passionate about creating systems that are not only efficient but also maintainable. Whether it's simplifying complex APIs, optimizing background jobs, or managing stakeholder expectations, I thrive in roles where I can be both a builder and a problem-solver.

Senior engineer with 10+ years in Rails

High response rate

⚒️ Experienced Ruby / Rails Engineer — 🇬🇧 English Native — 🙋‍♂️ Available March 2025 — 👇 Pitch Approaching 15 years as a professional software engineer and plenty more as a hobbyist, my purpose is to ship useful and worthwhile software. I can lead your team to launch your new MVP or bring your suffering app back to life, with a razor-sharp focus on generating value. I’ll ask the stupid questions that need to be asked and work closely with you to ensure time is spent delivering what your customers need, without the fluff they don’t. I've enjoyed working with all sorts of people in all sorts of companies, building all sorts of things. That means I'm capable of working on a broad variety of problems — from rapidly building MVPs in a tiny team to iterating on planet-scale microservices within a large organisation. I probably won't be able to patent a new algorithm to reduce load times by 0.05% across the board. But I will be able to help you find and remediate bottlenecks that are demonstrably causing your customers to bounce. I won't disappear into a cave for two weeks with a feature specification and come back with a perfect implementation. I'd rather iterate and communicate; in two weeks the entire feature may have been scrapped in favour of a different value-add. Let's build the right things well, rather than the wrong things perfectly. And I won't sit idly by if the team is clearly unhappy and underperforming. Whether I need to take the reins myself or inform others, everyone deserves to work in a positive environment, conducive to their happiness. Anything less produces bad software. So that's roughly what I do. Have a nice day!
