At Elly Analytics, I lead R&D for a 57-microservice marketing analytics platform, coordinating a team of nine while shaping architecture, development standards, and AI-assisted workflows. I built the API Gateway and Authentication Service from scratch, introduced dual-token authorization, and led the platform-wide migration for breaking changes.

I've delivered 7+ external integrations including Facebook, Amazon Ads, Reddit, GA4, PostHog, Shopify, and Airflow, and migrated 30+ importers to a unified architecture. I also improved batch database operations by 200x and have led engineering teams in high-reliability FinTech systems.
