At Cooee, I build marketing automation and analytics software for e-commerce brands. I created an embeddable JavaScript SDK used by 150+ production websites and the backend APIs for session lifecycle, live order tracking, campaign rendering, and discount locking.
I redesigned MongoDB aggregation pipelines across collections with millions of documents and added Redis caching, reducing analytics API p95 latency from about two seconds to under 500ms. I own NestJS services for analytics, campaigns, orders, and product management, and built four modules of Cooee's Angular analytics dashboard.
I also build event-driven workflows using queues, webhooks, cron jobs, and background workers that handle thousands of daily events. Beyond feature delivery, I handle data migrations, incident response, impact testing, monitoring, CI/CD, code reviews, and unit, E2E, and load testing.
Previously, at CodeCamber, I developed a cross-platform CRM app in React Native and TypeScript and built SEO-focused Next.js sites for client projects. I also built ProofLog, a tamper-evident audit logging service using Hono, Cloudflare Workers, PostgreSQL, and cryptographic hash chains.
