The Engineer Behind the Code

Backend Software Engineer with 3+ years building mission-critical fintech and banking infrastructure across Nepal. I specialize in transaction engines, event-driven architectures, and the kind of systems where downtime isn't an option - branchless banking platforms, instant KYC onboarding, and equity market integrations that power real financial institutions.
