What I'm looking for

I’m looking for a software engineering role where I can own reliable backend and product features end-to-end—using modern React/Node stacks, strong testing/CI/CD, and observability—while mentoring teammates and partnering closely with stakeholders.

I’m a software engineer who thrives on turning complex requirements into dependable products. I’ve built end-to-end systems using React and Node.js, with strong focus on reliability, observability, and clean engineering practices.

In my most recent role as a Lead Software Developer, I implemented a web application with React, Node.js, Keycloak, and SQL backed by Snowflake. I also designed a robust backend logging and error-notification system that maintained 99.9% uptime and enabled rapid incident response, plus event tracking with PostHog.

Across mobile and fintech projects, I’ve developed Android & iOS apps with TypeScript and React Native, including a checkout experience rolled out to nearly 88K active users. I care about mentorship and quality—improving code standards with linting, test-driven development, and CI/CD, while supporting teams through debugging and onboarding.

What energizes me is working close to stakeholders and cross-functional partners to deliver measurable impact. From building rental-deposit and rent-collection services with email and SMS integration to integrating banking protocols, I aim to ship thoughtfully and keep systems maintainable.
