What I'm looking for

I'm seeking a senior engineering role building scalable web and mobile applications with modern stacks, cloud deployment, CI/CD, clean architecture, and opportunities to mentor and drive measurable performance gains.

I am a Senior Full-Stack Developer with 8+ years building robust web and mobile applications for Fintech, EdTech, Logistics, SaaS, AI-powered platforms, and enterprise clients.

I specialize in React, React Native, TypeScript, Node.js and PostgreSQL, delivering scalable APIs, interactive dashboards and polished UIs. I design clean architecture, implement authentication flows, and build CI/CD pipelines for reliable deployments.

I have migrated legacy systems to modern stacks like React and Next.js, improving performance by 40%, and implemented microservices with NestJS and Docker to accelerate release cycles. I integrate third-party services such as Stripe, Plaid and Firebase to expand product capabilities.

I mentor junior developers, conduct code reviews, and champion SOLID principles, testing, and observability to maintain high code quality. I'm motivated to lead complex projects, mentor teams, and deliver high-performance, production-ready solutions.
