Lead Engineer / Senior Architect | October 2011 – Present
Bangalore, India

I have spent over 12 years developing distributed, multi-threaded software for the Philips Picture Archival and Communication System (PACS) in hospitals. Some key accomplishments include:

• Cloud-Native Migration: Led the architecture and migration of a cloud-native solution, covering cost estimation, performance analysis, and customer engagement. Transitioned from on-premise to a distributed microservice architecture, optimizing performance and scalability.
• High-Performance Streaming: Developed efficient streaming solutions for high-bandwidth data transmission and conducted POC studies for high-performance client viewing using WebAssembly.
• Security and SSO: Implemented security frameworks for microservices, including authentication, authorization (HMAC), DoS prevention, and Single Sign-On (SSO) using OpenID Connect.
• Performance Optimization: Enhanced the proprietary iSyntax algorithm using AVX and SSE3 instruction sets, achieving significant performance improvements.
• CI Pipeline & TDD: Introduced Test-Driven Development (TDD) and established a Continuous Integration (CI) pipeline, achieving 85% code coverage and improving software quality.

Technologies: C++11/17, C#.NET, AWS (EBS, S3, RDS, ECS), RabbitMQ, Redis, F5 Load Balancer, SSE3, AVX, Windows
