About
I've built and scaled high-throughput web applications at Wamo Labs, Spryker, and Metricool using Go, Python, Node.js, React, Ruby on Rails, PHP, and cloud infrastructure.
At Wamo Labs, I re-architected high-traffic Node.js services into Go microservices with gRPC, reducing p99 latency by 38% under peak load. I also implemented Redis caching that reduced database load by 45% and established GitHub Actions pipelines for blue-green Docker deployments to AWS.
I've delivered e-commerce, analytics, legal case-management, booking, and enterprise dashboard products from system design through production. I enjoy owning features end to end, improving performance, collaborating with product teams, and helping junior developers through code reviews.
