What I'm looking for

I’m looking for senior engineering roles building scalable, secure cloud-native SaaS products with strong engineering practices, mentoring opportunities, and cross-functional collaboration.

I am a Senior Full Stack Engineer with 10+ years building secure, high-performance SaaS platforms across healthcare, e-commerce, and casino-gaming industries. I design intuitive user interfaces and architect robust backend systems using Python and Node.js.

My work spans serverless, microservices, and monolithic architectures on AWS and GCP, leveraging Lambda, ECS/EKS, RDS, DynamoDB, and Cloud services to optimize performance and reliability. I build and secure APIs (REST, GraphQL, gRPC) and implement real-time features with WebSocket.

I have led end-to-end projects, implemented CI/CD pipelines, automated testing, and introduced monitoring and observability practices to reduce defects and accelerate releases. I mentor engineers and foster cross-functional collaboration to align technical solutions with business objectives.

I seek to bring pragmatic architecture, performance optimization, and security-first engineering to teams building scalable cloud-native products while continuing to adopt emerging technologies and drive continuous improvement.
