Designed and deployed scalable cloud infrastructure using AWS CDK, integrating services such as ECS, Secrets Manager, and Application Load Balancer (ALB) to run containerized applications with auto-scaling support.
Developed robust CI/CD pipelines using GitHub Actions, enabling automated deployments with rollback mechanisms to ensure production stability.
Built and maintained a medication database synchronized with the SNOMED CT medication dataset.
Implemented AI automation using OpenAI APIs (GPT-4o, GPT-4o mini) to extract and match medications and quantities from prescription PDFs and free-text prescriptions against internal and external pharmacy databases—significantly reducing manual effort.
Improved API performance by optimizing complex SQL queries and automated price updates for over 5,000 medications using NHS tariff data.

Architected and deployed a real-time data ingestion pipeline for commodity (crude oil, natural gas, power, etc) futures' prices, handling thousands of price updates per second using Redis, cron jobs, and PostgreSQL with TimescaleDB for time-series storage.
Built a high-performance WebSocket API in Rust to stream live prices to clients, designed for low latency and high concurrency at scale.
Developed authenticated Python REST APIs for secure access to historical data based on client access rules, and developed a Python client library package to consume live data from the WebSocket service.
Deployed the full infrastructure on DigitalOcean, including Rust and Python servers, Redis, and TimescaleDB; ensured high availability and efficient resource utilization.
