What I'm looking for

I want to build scalable, end-to-end products—owning architecture through production—where product thinking and reliable distributed systems matter, ideally in a startup/remote environment with autonomy and fast iteration.

I’m a software engineer with 4 years of experience and strong full-stack expertise, with a proven track record of building scalable products end-to-end—from architecture design to production deployment.

I’ve built backend-heavy systems using Node.js, TypeScript, and Go, while also delivering modern front-end and mobile experiences with React, Next.js, and React Native. I focus on distributed systems, API design, microservices, messaging, and database performance to ship reliable, maintainable products.

As a founder/CEO, I launched an AI-powered SaaS from 0 to 50+ active users in production, owning product discovery, architecture, full-stack development, and go-to-market execution with zero funding. I turn recurring user pain points into automation-first features that help technical professionals grow authority consistently.

In product and engineering roles, I’ve led microservices development and observability improvements, using Grafana, Prometheus, and GCP to reduce incident detection time. I’m a proactive leader—bridging technical depth with business value, and operating with end-to-end ownership.
