What I'm looking for

I’m looking for a remote Full-Stack/Senior Software Engineer role where I can build scalable, high-performance products using React, Next.js, Node.js, and TypeScript, take technical ownership, and continue growing with a strong engineering team.

At WebClues Infotech, I build production-grade features for a high-performance Forex Trading platform using Next.js, React, Node.js, TypeScript, Fastify, and PostgreSQL. I improved Lighthouse performance from 63 to 87 and reduced deployment time from 45+ minutes to 12 minutes through frontend and build optimization.

Previously, I led frontend development for four business-critical modules for JERA, Japan's largest power generation company, and mentored two junior developers. Across enterprise, trading, social media, and management systems, I've delivered REST APIs, real-time functionality, testing, performance improvements, and AI chatbot integrations.
