What I'm looking for

I seek a high-ownership engineering role building scalable, product-driven systems and AI features, with cross-functional collaboration, mentorship opportunities, and strong engineering practices.

I am a Senior Software Engineer with 10 years of experience building and scaling product-driven applications using Typescript, React, Next.js, Node.js, Python, and AWS. I have a strong track record of owning features from 0→1, delivering modular architectures and microservices, integrating AI capabilities, and improving reliability and observability in fast-paced startup and scale-up environments.

I lead end-to-end development, introduced comprehensive testing and CI/CD, and mentor junior engineers while collaborating cross-functionally to influence product direction. My contributions have reduced development time, improved API throughput and user engagement, and increased automated test coverage and deployment reliability.
