Resourceful full-stack developer with a heart for purpose-driven tech, skilled in Ruby on Rails and building digital solutions for real-world problems.

What makes me unique as a developer is the blend of purpose, adaptability, and real-world impact that drives my work. I didn’t get into software development simply to build cool apps — I started coding to solve problems that matter to people. From streamlining administrative systems for local government in Zimbabwe to creating an online marketplace that helps small businesses sell car parts more effectively, my projects are always rooted in tangible value and usability. One of my recent accomplishments is developing a digital change-of-use permit system for Harare City Council using Ruby on Rails. What makes this special isn’t just the tech stack — it’s the fact that I took a bureaucratic, paper-heavy process and transformed it into something efficient, trackable, and accessible. It’s a small but meaningful contribution toward digital transformation in a context where it's needed most. I’m passionate about building platforms that empower communities, particularly in underserved markets. Whether it’s launching PartsToGo, a growing car parts marketplace in Zimbabwe, or conceptualizing platforms like TendersZimbabwe, I love taking on the kind of challenges where impact matters more than hype. I bring not only the technical skills — full-stack development, systems thinking, clean and maintainable code — but also a strong sense of empathy and purpose to every line I write. I thrive where others may hesitate: limited resources, unclear paths, and bold ideas. My strength lies in turning vision into product, especially when the goal is to make life easier, more efficient, and more just for real people.

Ruby on Rails, React, and more...

I am a passionate full-stack developer, AI researcher, and aspiring biomedical engineer with a strong foundation in software development, data science, and hardware prototyping. My expertise lies in building scalable web applications, designing AI-driven solutions, and leading cross-disciplinary projects in wearable technology and healthcare analytics. In addition, my academic specialization is in data analytics, particularly in regard to bioinformatics, such as Clinical and Genome informatics. Analyzing data with a python-based scripting language, Snakemake, and constructing comprehensive analysis reports with genomics libraries as well as R markdown. With experience in full-stack development using React (Next.js), Express.js, Ruby on Rails, and cloud deployment on Google Cloud, Oracle Cloud, Fly.io, Render and Heroku, I have developed an inventory management platforms, and AI-driven predictive models, and am currently working on an e-commerce application. I thrive in roles that challenge me to innovate, whether it’s designing seamless user interfaces, optimizing backend performance, or integrating machine learning for real-world applications. Beyond software, I have worked on biomedical and sports tech innovations, including a head-mounted IMU wearable for motion tracking that outperformed industry standards in 3 metric analytics. I also have experience prior to my capstone collaborating in engineering teams to develop smaller prototypes for various technologies such as sepsis monitor, virtual reality training program for biomedical technicals, and various other small projects in my degree. My background in bioinformatics and AI research has allowed me to develop a sepsis prediction model using machine learning, focusing on optimizing predictive accuracy through feature engineering and statistical modeling. I am driven by curiosity, problem-solving, and a commitment to delivering impactful solutions. Whether it’s scaling a startup idea, designing AI models for healthcare, or crafting efficient backend architectures, I bring a blend of technical expertise and entrepreneurial vision.

Efficient and persistent.

Hello! My name is Manuel Lopez, and I'm a passionate and motivated developer eager to make an impact in the tech industry. I recently graduated from Durham College and am currently working as a dishwasher while I focus on advancing my career in development. My journey into programming started with a fascination for how things work at a fundamental level, which led me to explore both front-end and back-end development. One of my proudest accomplishments is creating a detailed 8085 microprocessor simulator, which allowed me to dive deep into low-level programming and computer architecture. This project, along with my work on a React Native multimedia application, highlights my ability to handle complex technical challenges and deliver high-quality results. Currently, I'm developing a CHIP-8 visualizer, an interactive tool that enhances understanding of the CHIP-8 emulator by visualizing memory interactions and display updates. I thrive on solving problems and learning new technologies. For instance, I'm actively participating in the ProtoHackers challenge, which is helping me refine my skills and stay current with industry trends. My unique combination of skills in both low-level and high-level programming, coupled with my determination and enthusiasm, makes me a valuable asset. I am committed to leveraging my abilities to contribute effectively to your team and help drive innovative solutions. If you’re looking for a developer who is not only technically proficient but also passionate about continuous learning and making a meaningful impact, I would be thrilled to bring my expertise and dedication to your company.

Software Engineer

Although I started my career as a designer back in 2000, throughout past 17 years I’ve been working with Rails building various web apps from small personal sites for me and my friends to huge multi-million SaaS projects, both private and governmental. And though most of my portfolio is a private work under NDAs, I have committed to several open source projects. Past several years I was working with Click Funnels, creating tools to automate OpenAPI generation. In particular, I created the open-source gem jbuilder-schema, which generates OpenAPI-compatible components from Jbuilder files, most Rails applications already have. Those can be used with Rswag for example, or we used them with bullet_train-api gem. I have plan to release gem that would fully generate OpenAPI specs for the application, based on its routes and Jbuilder files, so every Rails app may have API documentation for free. Now I have some free time so I’m writing a small app for iPhone for managing finances. I needed a library to calculate recurrent events but couldn’t find a good one for Swift. So I rewrote ruby-rrule gem into a Swift Package RRule and released that as open source as well. In my work I mostly like big and complex tasks, I love to dive deep and find elegant solutions. Creating a feel of some undercover magic for user is what really thrills my mind. Of course during my career I had different projects, with fresh and legacy code, I even had my own «Web Studio» working with several clients, and organized first IT conference in Crimea back in 2013.
