Senior Full Stack Developer with extensive experience building end-to-end web applications, scalable APIs, and complete business software solutions. I design and deliver products across the entire stack — from React and Next.js frontends to Python and Node.js backends.
Experienced in integrating AI-driven features that streamline business processes, improve operational efficiency, and support data-driven decision-making. Whether it's a client-facing interface or a complex automation pipeline — I focus on solutions that are reliable, scalable, and built to last.
Lead frontend development using modern frameworks (React, Next.js) integrated with well-structured, maintainable server-side logic. Design and implement machine learning and optimization tools for business-oriented applications. Build scalable Python-based systems for data processing, automation, and intelligent software functionality. Create practical AI solutions that help businesses improve efficiency, reduce manual work, and optimize operational processes.
Worked on server-side logic, API integration, and database-related functionality. Built and maintained rich, interactive user interfaces using modern JavaScript frameworks. Collaborated cross-functionally with design, product, and backend teams to ship stable, high-quality full stack features on schedule.
