About Me

Building the invisible

Platform Engineering

My specialty lies in SDK development, monetization systems, and platform-scale performance. I believe great engineering shouldn't be noticed—it just feels fast, fluid, and remarkably reliable.

Impact & Scale

From driving million-dollar IAP revenue flows to reducing app crashes down to 0.01% while serving 50k+ DAU. I build the infrastructure that product teams rely on to grow confidently.
