Vitto Microfinance AI

Software Engineer Intern

  • Built a Notification Microservice from scratch — 99.9% delivery rate across 500K+ targeted monthly alerts with zero message loss.
  • Integrated UPI QR payments with YES BANK, processing INR 10M+ in transaction volume with zero-fault tolerance.
  • Cut database read latency by 90% using Redis caching with smart invalidation — turning 200ms queries into 20ms.
  • Shrank Docker images by 70% (Ubuntu → Alpine), accelerating CI/CD pipelines across all microservices.

The Great Migration

Samsung R&D

  • Migrated legacy Node.js monoliths into a distributed Java Spring Boot microservice mesh — zero-downtime cutover serving production traffic.
  • Containerized the entire platform on AWS EKS, orchestrating 100M+ daily API requests through Kubernetes with auto-scaling and self-healing pods.
  • Drove $18,000/month in recurring cloud savings by right-sizing instances, optimizing networking, and eliminating idle compute.

Data & Observability

Samsung R&D

  • Replaced a heavyweight ELK stack with a serverless pipeline (S3 + Athena + Superset), handling telemetry from 100M+ daily requests at a fraction of the cost.
  • Maintained sub-millisecond real-time dashboards by decoupling hot-path analytics from cold storage — zero impact on engineering observability.
  • Reduced logging and monitoring costs by $15,000/month while increasing data retention from 7 days to 90 days.

The AI & Automation Era

Samsung R&D

  • Pioneered natural language control mechanisms by leading the development of an internal LLM portal, empowering over 100 service owners to manage vast AWS/GCP resources via plain English and slashing manual console effort by 70%.
  • Delivered plug-and-play Model Context Protocol (MCP) servers integrated with Trusted Advisor & Cost Explorer, unlocking over $300,000 in top-level cloud optimizations.
  • Spearheaded a multi-threaded Redis asynchronous job processing engine armed with DKMS encryption to securely and efficiently execute 5 Million+ jobs daily.

Financial AI Assistant

Full-Stack GenAI Project

  • Built an end-to-end personal finance AI that connects Gemini's reasoning to real financial APIs — budgeting, expense splitting, and insights in natural language.
  • Created a custom Splitwise MCP server (FastAPI + React), wrapping 20+ fragmented APIs behind a unified OAuth + LLM abstraction layer.
  • Reduced token usage by 70% through context windowing and smart prompt engineering — making the agent fast and cost-efficient.
