Full Stack Software Engineer

About

Why should you Hire me ?

Because I pick up a feature, drive it to completion, and deliver it into the product used by real users.

I’ve built and shipped real features across UI, APIs, and database integrations. I’m comfortable in messy problem spaces: clarifying scope, designing the flow, handling edge cases, and making the system observable and reliable in production.

Ownership

I take a module from unclear requirements → shipped release with clarity and accountability.

Reliability

Idempotency, edge cases, retries, validation, and failure-safe workflows are default for me.

Speed without chaos

Fast execution with clean structure, so that product stays maintainable as it grows.

Experience

What I’ve delivered in production, and what I was responsible for.
