14+ years shipping end-to-end products with React, Next.js, Node, and Java. I pair solid engineering with practical AI assistants, automation, and smarter workflows so delivery stays fast without sacrificing quality.
Who I Am
Full stack developer with a strong record in team leadership, complex integrations, and long-lived production systems.
I'm Haresh Godhani, a full stack developer based in Gujarat, India with 14+ years in the industry. I work across React.js / Next.js, Node.js (NestJS, Express, Fastify), Java / Spring Boot, Angular, and cloud data stores including MongoDB, PostgreSQL, MySQL, and Firebase.
I've led engineering efforts, mentored developers, and partnered with cross-functional teams to deliver medium and large-scale applications from marketing and ad-tech automation to fintech integrations and enterprise Angular/Java stacks.
I care about code quality, clear architecture, and practical delivery: automated workflows where they save time, solid APIs, and UIs that stay maintainable as products grow.
From API design and integrations to responsive frontends, I own features across the stack and keep production systems healthy.
Designing practical AI features with retrieval-augmented generation (RAG), agentic workflows, and automation pipelines that improve developer and business outcomes.
Led teams at OneIT and beyond: technical guidance, code review, and raising the bar on testing and automation (Docker, Jenkins, Protractor).
Built ad platform integrations (Google Ads, Facebook Ads), chargeback/fintech workflows (Ethoca, Verifi, AMEX), and complex backend services.
Where I've Worked
