What I'm looking for

I seek senior engineering roles where I can build scalable systems, lead architecture and CI/CD improvements, mentor teams, and collaborate with product and ML to deliver high-impact SaaS products.

I am a results-oriented Senior Full Stack Engineer with over eight years building scalable web and SaaS platforms across fintech, e-commerce, gaming, and AI.

I focus on JavaScript and TypeScript frontends (React/Next.js, Angular, Vue) and backend services in Node.js, Python, and Ruby, with significant experience on AWS and GCP. I've designed microservices, API gateways, and event-driven architectures to deliver low-latency, reliable systems.

My work includes launching production casino game services, creating an AI-driven photo generation platform, and leading an e-commerce migration to microservices—each improving performance, developer productivity, or user experience. I also implement CI/CD, testing strategies, infrastructure-as-code, and monitoring to reduce friction and incidents.

I enjoy mentoring teams, running Agile ceremonies, and collaborating with product, design, and ML engineers to ship high-impact features that align with business goals.
