I’m a software developer with over four years of experience in building, maintaining, and deploying web applications. I specialize in Ruby on Rails and enjoy solving complex problems with simple, efficient solutions. How I Started I began my career as an intern at a small software consulting startup. That’s where I discovered Ruby and Ruby on Rails. I picked up the fundamentals quickly and was immediately drawn to its elegance and flexibility. My first project was maintaining a large fashion rental platform. At first, the sheer size of the codebase was daunting, but I saw it as a challenge. I dove into debugging and optimization, fixing bugs, improving performance, and eliminating bottlenecks. These experiences gave me a solid understanding of the system and laid the foundation for my career. Over time, I moved from maintenance to developing new features. This transition gave me the opportunity to design and implement functionality that directly impacted the business. Key Contributions Here are some of the key contributions I’ve made to projects: - Third-Party Authentication: Rebuilt Google, Facebook, and Apple authentication features from scratch after library issues caused them to fail. - User Reviews: Developed a review system for renters and lenders, improving transparency and trust. - Mobile App Overhaul: Updated a hybrid iOS app to ensure compatibility with the latest framework. - SMS Notifications: Added SMS alerts to keep users informed about their transactions. - “Buy Now” Feature: Enabled lenders to sell items, responding to customer demand and expanding the platform’s offerings. - Stripe Payment Integration: Built backend features for handling disputes and charges. - Real-Time Messaging: Migrated the messaging system from ActionCable to Turbo Hotwire and redesigned the user interface. These contributions significantly boosted the company's revenue growth, attracted new investments, and paved the way for expansion into multiple white-label platforms. I was also entrusted with architecting and leading the development of the first three white-label platforms, implementing the same infrastructure as the base rental platform. What I Do Now I currently work on multiple projects across industries, including eCommerce, SEO, Marketing and learning platforms. My role includes development, maintenance, and DevOps. I take pride in delivering stable, scalable systems. Why Me? Coding excites me because it’s not just about writing lines of code—it’s about creating solutions, crafting experiences, and turning complex challenges into elegant outcomes. Each problem I solve gives me a profound sense of accomplishment, driving me to push boundaries and exceed expectations. When I work on something, I don’t just aim to get it done; I aim to do it exceptionally well. If you’re looking for someone who not only does the work but genuinely loves it, then I’m exactly who you’re looking for.

I was first introduced to coding in 2013 at my OOP undergrad class using good old C. I really liked solving challenges by writing code and curiosity drove me to learn JavaScript on my own for web development. Over the years I tinkered with a lot of frameworks but stuck with rails since 2021. Nowadays, I am passionate about design patterns and exploring how things work under the hood. This came after reading metaprogramming ruby and object oriented ruby books. Apart from that, I enjoy working with rails and hotwire to build my side projects and also for clients. In my free time, I enjoy exploring restaurants with my wife and also watching movies. I am fun to work with and enjoy talking to people from different cultures.
