VIJAYAKUMAR G.

I help product teams integrate AI into their existing Java/Spring Boot systems — turning slow, manual workflows into intelligent, conversational experiences. Recently I built an AI-powered campaign creation system for a leading Indian OTT advertising platform (100M+ users) — replacing complex form-based operations with a conversational AI interface using Spring AI and Claude. The result: faster campaign setup with significantly less manual effort. With 14+ years of delivery across OTT, AdTech, retail, healthcare and fintech — I understand that AI only adds value when it fits your existing architecture and solves a real business problem. I don't prototype. I build production-ready systems. What I deliver: - AI workflow automation inside existing Java/Spring Boot systems - Conversational interfaces replacing form-heavy operations - Microservices architecture and REST/GraphQL API design - Full stack delivery — Spring Boot backend through React frontend Tech I work with: Spring Boot · Spring AI · Claude API · MCP · React · Flutter · AWS · Docker · PostgreSQL · MongoDB My background includes: - Ex-Technical Architect and Java Team Lead - Delivered for Fortune 500s and high-scale startups - $40K+ earned on Upwork across 14 contracts · 3,100+ hours Best fit for: Product companies in OTT, AdTech or fintech with an existing Java backend looking to add AI capabilities — without rebuilding from scratch.
