Systems I've built

R

Re-Architecting a Legacy Forex CRM Without Downtime

Problem

The CRM had grown organically over several years into a tightly coupled system. Frontend and backend changes were deeply intertwined, deployments were risky, and performance issues were increasingly common under production load. A full rewrite was not an option due to active users and continuous business requirements.

How I approach problems

01

Understand

Map the current flow, identify bottlenecks, and clarify technical and business constraints before writing any code.

02

Design

Build for retries, timeouts, recovery paths, and visibility into production behavior. Assume failure happens.

03

Ship

Roll out incrementally, monitor closely, and iterate based on real-world feedback. Production is the test.
