CI/CD Overhaul & Performance Tuning for a Growth-Stage Platform
Company and product names are withheld under NDA. The problem, solution, and my role below are real, from my day-to-day work leading a 4-person backend team within an 11-person cross-functional org at a growth-stage startup.
The business problem
Deployments were manual, slow, and error-prone. As transaction volume grew, key services also started struggling to keep up under load, with database queries becoming a bottleneck.
The solution
I replaced manual deployments with full CI/CD automation using Bitbucket Pipelines, Docker, and Terraform, and moved key services to a serverless architecture on AWS Lambda and API Gateway. On the data side, I restructured database partitioning and reworked access patterns to cut query overhead.
My role
I led the 4-person backend team responsible for this system end-to-end — architecture, implementation, and rollout — within an 11-person cross-functional org.
Technical challenges
Migrating live services to serverless without downtime meant a careful incremental rollout — running old and new paths in parallel, monitoring closely, and cutting over only once the new path matched the old one's behavior under real traffic.
Results
Need CI/CD automation, cloud infrastructure, or performance tuning done right? Let's talk through what you're building.
