About

Software Engineer with 2+ years of experience building scalable, reliable web and backend systems in the fintech domain. Currently working at TodayPay, where I work primarily with Go, PostgreSQL, Redis, React, and Next.js to design and develop production-grade applications and services. My focus is on building systems that are reliable, maintainable, and scalable — from backend services and APIs to database design, integrations, and end-to-end product development. I enjoy understanding problems deeply and translating them into simple, efficient, and robust engineering solutions. I’m continuously expanding my expertise in system design, distributed systems, cloud infrastructure, and DevOps, while also exploring AI-assisted and agentic development workflows to improve how software is designed, built, tested, and deployed. Currently, I’m exploring opportunities in software engineering where I can work on challenging technical problems, contribute to scalable systems, and grow into an engineer capable of designing and owning systems end-to-end.
