01Summary

I build the connective tissue of modern finance — recently architecting a banking core middleware handling 25,000 daily transactions across 1B+ NPR in volume, and weaving Agentic AI workflows into legacy infrastructure. My edge is bridging complex, event-driven backends with seamless cross-platform experiences.

Principal Architect & Engineering Lead
  • ▹Architected a high-concurrency Golang (Gin) middleware decoupling legacy banking cores from modern third-party APIs — now processing 25,000+ daily transactions (~1B NPR) at 99.99% uptime.
  • ▹Led end-to-end engineering of a multi-tenant SaaS ERP/POS: resilient Golang backend, Next.js analytics dashboard, and an offline-first Flutter POS with seamless cross-device sync.
  • ▹Engineered a Redis + Go-Work background worker ingesting millions of financial records daily from PostgreSQL, cutting reporting latency by 60%.
  • ▹Containerized all microservices with Docker on AWS (Lambda / API Gateway) and stood up a centralized OAuth2/OIDC identity provider for role-based access.
  • ▹Spearheading multi-modal AI R&D — LLMs/Vector DBs for automated financial workflows and a generative-CV 'Wearit' virtual try-on engine.
