Software Engineer with 7+ years building web products fast—payments, auth, real-time features, and clean architectures.
What I'm looking for
I’m a Software Engineer with 7+ years of experience building web applications from the ground up. I turn ideas into deployed products fast, integrating payments, auth, scheduling, real-time features, and third-party APIs into clean, maintainable architectures using a core stack of React, TypeScript, NestJS, Node.js, and PostgreSQL.
I’ve led teams and owned technical decisions end-to-end—turning product goals into robust architecture. My background spans fintech, real-time communication, e-commerce, and creator economy platforms, where I focus on clarity, maintainability, and shipping.
In recent roles, I architected and built a creator economy platform from scratch, integrating Stripe and establishing CI/CD pipelines that reduced deployment time by 60%. I also developed real-time audio/video capabilities with speech-to-text and translation (reducing setup errors by 40%), and delivered a retail MVP in under 3 weeks with sub-second page loads and 99.9% uptime. I’m driven by measurable outcomes, strong engineering fundamentals (DDD/TDD where applicable), and fast iteration without sacrificing quality.
