What I'm looking for

I’m seeking a full-time Software Engineer role to design and ship reliable, high-impact backend systems—building scalable services and APIs with strong uptime, clean architecture, and practical performance improvements.

I’m a Backend Software Engineer with 2 year of industry experience at RapiPay Fintech, where I build scalable backend systems, microservices, and RESTful APIs. I’ve delivered production services serving 500+ merchants and 10,000+ daily transactions at 99.9% uptime, with hands-on work across microservices, databases, messaging, and infrastructure.

At RapiPay, I engineered a config-driven multi-bank reconciliation service, built a Redis-idempotent webhook handler that eliminated 100% duplicate transactions, and led an L1–L4 hierarchical credit system with role-based approvals and automated wallet transactions. I also launched an AI-powered Loan MIS assistant using LangChain, Groq LLM, and RAG—converting natural-language questions into MongoDB pipelines and cutting turnaround from hours to seconds.
