About

I'm a Staff Engineer with 13+ years of experience building scalable backend and full-stack applications across enterprise and product environments. Throughout my career, I've enjoyed solving complex engineering challenges, designing scalable systems, building reliable APIs, and mentoring engineers to deliver high-quality software. My core expertise includes Ruby on Rails, Python (FastAPI), Vue.js, AWS, MongoDB, MySQL, Redis, Kafka, Docker, CI/CD, Modular Monolith Architecture, and Multi-tenant Architecture. I have hands-on experience designing and developing secure REST APIs, implementing authentication and authorization using OAuth2/JWT, optimizing application performance, and leveraging observability tools such as ELK Stack and New Relic to monitor, troubleshoot, and maintain reliable production systems. I enjoy working across the entire software development lifecycle—from understanding business requirements and designing scalable architectures to implementing features, optimizing performance, conducting code reviews, mentoring engineers, and driving engineering best practices. I thrive in collaborative teams where ownership, continuous learning, and delivering customer value are at the core of the engineering culture. I'm particularly excited about the future of AI and Generative AI. I'm actively investing time in expanding my knowledge of Large Language Models (LLMs), AI-powered applications, and modern AI engineering. My goal is to combine my strong backend engineering experience with AI technologies to build intelligent, scalable products while continuing to learn and grow alongside innovative teams. I'm always interested in connecting with engineers, founders, and recruiters who are building impactful products. I'm currently open to remote opportunities and hybrid roles in Bengaluru, particularly with product companies and startups in AI & ML, SaaS, FinTech, AgriTech, EdTech, E-commerce, Healthcare, OTT, and Real Estate Technology. Let's connect if you're building something exciting or looking for someone passionate about scalable backend systems, modern software engineering, and the next generation of AI-powered products.
