What I'm looking for

I'm looking for remote or relocation opportunities where I can build secure, scalable backend systems, deploy AWS cloud infrastructure, and contribute to reliable products in regulated or mission-critical environments.

At DK Bank, I build and maintain backend APIs and microservices in Python with FastAPI for customer-facing digital banking systems. I also developed a rule-based Customer Risk Rating system for individual and corporate onboarding using DynamoDB.

I design and deploy AWS infrastructure with CDK and Serverless, working across Lambda, API Gateway, EC2, S3, VPCs, security groups, routing, domains, and load balancers. My database work includes PostgreSQL and DynamoDB, with attention to schema design, query optimization, and security.

My experience also spans network infrastructure, Tier-2 support, technical documentation, Git-based code reviews, and reliable delivery in regulated banking environments.
