About

Engineer focused on systems that hold up at scale.

I design and ship backend platforms and AI systems that stay reliable under real-world load.

I'm a Lead Software Engineer with 8+ years of experience building distributed backend systems and cloud-native applications. Most of my work lives at the intersection of high-throughput APIs and the infrastructure that runs them.

On the backend side, I work primarily with Python and FastAPI, backed by PostgreSQL and Redis. I ship and operate these systems on AWS using Kubernetes, Docker, and Terraform, with delivery pipelines through Jenkins and observability via Prometheus and Grafana.

More recently I've been building production GenAI systems — retrieval-augmented generation pipelines and agentic workflows with RAG and LangGraph that ground LLMs in real enterprise data.

Retrieval-augmented assistant for internal knowledge

Enterprise RAG Assistant

A production-grade retrieval-augmented generation assistant that grounds LLM answers in enterprise documents. Built with a chunking pipeline, hybrid vector + keyword search over Qdrant, and a LangGraph orchestration layer that supports multi-step reasoning, citations, and guardrails.

Challenge: Reducing hallucinations on a 2M-document corpus while keeping p95 retrieval latency under 300ms — solved with hybrid search, reranking, and a citation-grounding step in the graph.

High-throughput API platform serving millions of requests

Distributed FastAPI Backend

A horizontally-scalable FastAPI platform with async PostgreSQL, Redis caching, and Kafka-based event streaming. Designed for multi-region deployment on EKS with autoscaling, circuit breakers, and structured observability end-to-end.

Challenge: Sustaining 50k RPS during traffic spikes without degrading p99 — solved with Redis-backed idempotency, connection pooling via PgBouncer, and Kafka partitioning for backpressure.

Cloud-Native Microservices Platform

An internal platform that takes services from commit to production on EKS using Terraform-provisioned infrastructure, ArgoCD GitOps, and a Prometheus + Grafana observability stack. Includes golden-path templates and SLO-based alerting.

Challenge: Cutting deployment lead time from days to minutes while keeping rollback safe — solved with progressive delivery, canary analysis, and infrastructure-as-code modules.
