What I'm looking for

I seek senior engineering roles where I can lead technical direction, mentor teams, build scalable, reliable SaaS systems, modernize architecture, and deliver measurable product impact.

I am a Senior Full-Stack Software Engineer with 9+ years building enterprise-scale SaaS and data-driven web platforms, focused on maintainable architecture, system reliability, and performance at scale.

I have delivered high-impact production systems using React, TypeScript, FastAPI, NestJS, and cloud-native patterns, led major framework upgrades, and improved delivery velocity and runtime stability through design systems, typed API contracts, and CI/CD automation.

I lead by example and mentor teams, prioritizing durable technical decisions, secure API design, and observable, resilient services that support business-critical workflows.
