Senior Full-Stack & AI Engineer | React, TypeScript, Node.js, Python | Enterprise SaaS, Healthcare, Logistics & Telecom
I am a Senior Full-Stack and AI Engineer with 7+ years of experience designing, building, and shipping production software across enterprise SaaS, healthcare, logistics and supply chain, telecom, e-commerce, and AI-enabled products.
I work across the complete product lifecycle—from ambiguous business requirements and system architecture to frontend development, backend APIs, database design, cloud infrastructure, third-party integrations, testing, deployment, and production support. My core stack is React, Next.js, TypeScript, Node.js, Express, and NestJS, supported by strong experience with Python, PHP/Laravel, AWS, Docker, Kubernetes, SQL, Redis, REST, GraphQL, and WebSockets.
I use Cursor, Claude Code, GitHub Copilot, and Codex in my daily engineering workflow for codebase analysis, rapid prototyping, debugging, refactoring, code review, test generation, documentation, and modernization of unfamiliar or legacy systems.
