What I'm looking for

I’m looking for teams where I can build resilient backend and full-stack products—shipping secure fintech/AI features, collaborating closely, and using data-driven thinking to continuously improve performance and reliability.

I’m a Software Developer focused on building resilient, production-ready systems—especially where security, reliability, and speed to integrate matter. I’ve worked across fintech payment orchestration and AI-powered document workflows, with a strong emphasis on architecture that handles real-world failure modes.

At Payomatix Technologies (Jun 2025–Present), I developed PayXBorder, a modular fintech payment orchestration platform that supports crypto on/off-ramp and IBAN/fiat routing. I built scalable backend services with Node.js, Express, PostgreSQL, and Prisma, and I implemented optimized failure handling and real-time multi-provider switching to improve transaction resilience for high-risk payment flows.

I also architected KYC onboarding workflows designed to be compliance-ready, reducing merchant onboarding time while supporting regulated operations. In parallel, I improved infrastructure for PayAgency by enhancing routing strategies that keep transactions moving even when providers underperform.

Before that, as a Full Stack Engineer at Girnar AI Innovation Lab (Nov 2024–May 2025), I developed an AI-driven document intelligence system using OpenAI, Gemini, and Grok APIs to extract structured data at scale. I’ve also built analytics dashboards, frontend architecture for a Voice AI customer-care platform, and a WhatsApp automation module using the WhatsApp Cloud API to support dynamic templates and scalable messaging operations.
