At CherryPick Agency IT, I grew from backend developer to backend tech lead, guiding a team of 4–5 engineers and building products for users in Australia, Hong Kong, and Russia. On PadelApp, I developed booking and payment flows with a slot lock and idempotent webhook handling, so retries don’t create duplicate bookings or charges.
Across projects including Wello AI, Project X, and ELECTRO.CARS, I’ve built NestJS backends, payment integrations, and production monitoring. I also designed and built the new TVAITI 2.0 backend, with nine microservices, 69 PostgreSQL models, and 92 migrations, and brought it to release readiness.
