Message

At ScienceSoft, I architected Python and Go backend platforms for automation workflows and operational tooling. I improved REST API response times by 2x and integrated OpenAI APIs and LLM workflows into production systems.

I also designed event-driven workflows with AWS Lambda and Google Pub/Sub, and developed Node.js real-time communication services. I helped modernize infrastructure to Kubernetes with CI/CD and observability, reducing production incidents by 40%.

At SumatoSoft, I built Python services and Go microservices for customer engagement and messaging platforms, and developed event-processing and personalization services that reduced processing latency by 20%. Earlier, at UST, I built Node.js and Django services and APIs supporting PayPal merchant onboarding, disputes, and transaction workflows.
