About Me

Building dependable software for products that need to move fast without breaking trust.

Based in San Jose with a Master's in Computer Science, I work across backend engineering, applied AI, cloud infrastructure, and full-stack development. My experience spans fintech platforms, AI support agents that automate repetitive operations, and customer-facing products where performance and reliability matter every day.

The common thread is practical engineering: taking complex requirements, shaping them into clear systems, and shipping software that teams can trust in production. Always open to strong engineering teams, meaningful product problems, and conversations that start with an interesting idea.

Software Engineer II

Apr 2025 - Present

San Jose, CA

  • Built Java/Spring Boot repayment microservices on Oracle and GCP with Redis caching, processing 10M+ daily transactions across 16 products in 8 countries with exactly-once execution guarantees.
  • Delivered end-to-end Spring Batch reconciliation over Kafka, matching daily repayment event counts against Fineract SOR totals via COB events to detect silent data loss and guarantee per-product data integrity.
  • Engineered idempotent request handling with fingerprinting, audit-trail replay, and automated failure recovery, eliminating duplicate-payment incidents across distributed repayment services.
  • Shipped real-time data pipeline enriching 500K+ repayment events with risk signals to power fraud detection and trigger automated payment holds via REST APIs, improving model recall by ~15%.
  • Owned on-call rotation, ran canary deployments via Harness with Docker, monitored with Datadog and Splunk, and root-caused live incidents using BigQuery to ship fixes across multiple repayment services

AI Engineer

Jul 2024 - Apr 2025

Sunnyvale, CA

  • Architected production AI support agent in Python with LangChain, LangGraph, and MCP-based tool calling, integrating telemetry and internal RESTful APIs to automate 30% of repetitive support workflows on a multi-tenant CMMS platform.
  • Designed RAG pipeline with ChromaDB, OpenAI embeddings, and Pandas/NumPy preprocessing, implementing document chunking and metadata filtering to lift retrieval accuracy by 60% for technician troubleshooting.
  • Deployed quantized local LLM with PyTorch and Hugging Face Transformers on NVIDIA Jetson Orin Nano, enabling sub-second edge inference for privacy-sensitive operations and removing external AI API dependency.
  • Cut Azure infrastructure spend by 20% and deployment time by 60% through Terraform based IaC, GitHub Actions optimization, and caching high volume read paths with Redis.
