By The Numbers
About Me
Passionate and results-driven Software Developer II with over 7 years of experience designing and delivering scalable, secure, and high-performance applications across FinTech, Cloud, and Data Engineering domains. I specialize in building enterprise-grade microservices, payment systems, and analytics pipelines that process millions of transactions daily for clients like American Express and Wells Fargo.
I thrive in solving complex backend challenges, optimizing performance, and automating CI/CD pipelines to accelerate delivery. My career journey reflects a consistent progression — from coding learning systems in Nepal to architecting financial APIs in New York.
💡 I'm currently focused on leveraging Java, Python, AWS, and Spring Boot to create API-driven architectures that power digital payments, fraud detection, and risk analytics.
🚀 Core Strengths
🤝 Always open to collaborations, mentorship, and backend / cloud engineering roles where impact and innovation meet.
