What I'm looking for

I'm looking to build and lead end-to-end enterprise applications, particularly Java, Spring Boot, Angular, payment integration, and compliance API solutions, while contributing through architecture, delivery ownership, and mentoring.

At JRK Consulting Services, I build and deploy Java, Spring Boot, and Angular applications from architecture through production release. I've independently delivered retail, ticketing, workflow, recruitment, and jewellery platforms end-to-end.

I integrate payment gateways including Pine Labs, Paytm, Razorpay, Cashfree, Easebuzz, HDFC SmartGateway, CCAvenue, HitachiPOS, and SBI Payments. I've also built GST e-Invoice and e-Way Bill integrations, handling real-time compliance workflows, signed IRN responses, QR codes, validation, and retry scenarios.

As a sole technical lead, I own architecture, sprint planning, code reviews, client delivery, and junior developer mentoring. I use Codex and Claude Code for refactoring, prototyping, and full application builds while maintaining delivery speed and code quality.
