What I'm looking for

I’m looking for a backend role where I can design scalable, secure Python services and microservices, and keep pushing reliability through architecture, CI/CD, and monitoring while working closely with product and frontend teams.

I build Python backend systems where reliability matters, from Clickpost’s payment processing to Publicis Sapient’s IT data control APIs. I’ve designed RESTful APIs, microservices, and database schemas, and I work closely with frontend and product teams for clean integrations and requirement gathering.

At Clickpost, I implemented Kafka-based event-driven infrastructure, integrated multiple payment gateways with PostgreSQL transaction management, and reduced system failures through error handling and security best practices. I also improved CI/CD pipelines with Jenkins and Docker to cut deployment time, while optimizing performance for high daily transaction volumes.

More recently, at Publicis Sapient, I’ve designed FastAPI REST APIs with OOP principles and extensible factory patterns, plus audit and approval flows for controls and data hops. I also use caching with Redis and deploy monitoring and reliability improvements with tools like ELK in my earlier role at Twisted Mountain Animation.
