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.

I've also leveraged AWS Bedrock with Claude 3.7 to generate organizational insights reports, improving decision-making efficiency by 40%.
