Senior Full-Stack Python Developer at McKinsey & Company

June 1, 2024 - Present

Led development of FastAPI and Django microservices powering analytics accelerators and diagnostic engines for global clients. Implemented modular service boundaries, strict validation, and gRPC-based contracts to orchestrate modeling engines and enrichment pipelines on AWS EKS. Built an event-driven backbone with AWS SQS/SNS handling over 100k messages/day across tenants, improving fault isolation. Designed SSR/ISR-enabled React/Next.js frontends for consultant dashboards and optimized multi-tenant PostgreSQL schemas for analytics, achieving notable query performance gains. Established GitOps with ArgoCD and Terraform for reproducible environments, and an observability stack (Prometheus, Grafana, ELK, Sentry) to accelerate issue resolution. Introduced TDD/BDD with pytest and contract testing, and standardized OAuth2/JWT security with AWS Secrets Manager. Devised CI/CD pipelines with container scans and runtime policy gates, reducing deployment times and maintaining high automation.

Senior Full-Stack Python Developer at BBH

August 1, 2021 - September 1, 2023

Built FastAPI-based microservices to process 15k–40k trade confirmations per hour using async streaming and pooled DB connections. Replaced a synchronous Django module with an async FastAPI service, cutting API latency and removing bottlenecks. Designed PostgreSQL schemas for trades/positions/risk metrics with partitioning and partial indexes, improving aggregations under load. Implemented a Redis cache for instruments and account metadata, reducing backend reads by 70–80%. Created an async Celery-based ingestion/compliance pipeline and a GraphQL gateway to unify FastAPI/Django data. Integrated Elasticsearch for regulatory document search with sub-200 ms retrieval. Optimized intraday ETL with asyncio/pandas, shortening risk recalculation cycles. Deployed to Azure AKS with Terraform, set up observability (Prometheus, Grafana, ELK), and enhanced UI performance with deterministic Redux patterns.
