What I'm looking for

I'm looking to build and scale reliable SaaS platforms where I can own full-stack delivery, solve complex performance and data challenges, improve engineering standards, and mentor teammates.

At Velaris, I've built and owned end-to-end SaaS features across React, Node.js, PostgreSQL, AWS, and third-party integrations. I led the Segments migration from TinyBird/DMS/Kinesis to PeerDB and ClickHouse, cutting costs by 80%, more than doubling query performance, and reducing tenant onboarding from 45 minutes to 5 minutes.

I've improved API latency, introduced company-wide caching and observability standards, resolved large-scale data corruption, and delivered integrations including Google Meet, Salesforce, and HubSpot. I also mentor junior engineers, contribute to distributed-systems learning, and use AI-augmented development practices to improve code review and performance analysis.
