## About

```text
At WorkL for Business, I optimized PostgreSQL benchmark performance from 18 seconds to under 5 seconds and designed architecture for a distributed AI processing platform.

I build cloud-native backend services with Python, Node.js, MongoDB, AWS, GraphQL, Docker, and OpenAI APIs. My orchestration platform improved asynchronous processing speed by 30%, while Dockerized AWS deployments reduced release time by 20%.

At SilverSky Technologies, I built an email attachment security pipeline and asynchronous services that reduced threat-detection response time by 30%. I also delivered Single Sign-On automation for more than 1,000 enterprise users.

Across SaaS, cybersecurity, banking, insurance, ecommerce, and defence, I've led teams of up to eight engineers and modernized backend systems for greater scalability, resilience, and maintainability.
