Credentials & Experience

Directing the architecture and engineering execution of a multi-tenant Decentralized Clinical Trial (DCT) platform handling sensitive patient telemetry and distributed clinical workflows.

• Architect and scale distributed Node.js/TypeScript microservices and modular micro-frontends adhering strictly to GCP, HIPAA, and 21 CFR Part 11 regulatory standards.
• Lead a cross-functional squad of 6 senior engineers, institutionalizing RFC architectural reviews, automated contract testing, and domain-driven service boundaries.
• Pioneer agentic workflow automation and deterministic validation patterns to accelerate clinical trial protocol configuration and data intake.

Appointed by Google as an independent subject matter expert to mentor, educate, and advocate for cloud-native architectures across APAC.

• Delivered deep-dive technical keynotes, workshops, and architectural masterclasses on Google Cloud Platform, Kubernetes container orchestration, and microservices patterns.
• Partnered with Google Developer Relations to validate pre-release developer tooling, providing direct engineering feedback into cloud product roadmaps.
• Mentored hundreds of software engineers, startups, and university students on distributed systems resilience, Docker containers, and cloud migration strategies.

Led frontend architecture and platform infrastructure for an enterprise contract lifecycle management (CLM) SaaS product.

• Engineered a federated micro-frontend framework in React and event-driven backend services supporting high-concurrency document orchestration.
• Designed and implemented a granular attribute-based access control (ABAC) engine using dynamic workflow state machines to secure sensitive contract operations.
• Spearheaded the enterprise design system with Storybook and automated visual testing, standardizing UI consistency across all squads.
• Authored Terraform Infrastructure-as-Code modules and automated GitLab CI/CD pipelines, drastically reducing release failure rates.

Led the Site Reliability and DevOps practice safeguarding 99.99% availability for Sysco Shop, the flagship multi-billion dollar enterprise foodservice commerce platform.

• Managed a dedicated team of 6 SREs, DevOps engineers, and support specialists overseeing production operations, infrastructure scaling, and 24/7 on-call rotations.
• Designed full-stack observability and anomaly detection pipelines across AWS infrastructure, reducing mean-time-to-detection (MTTD) by over 40%.
• Established automated zero-downtime deployment pipelines, blue/green rollout strategies, and codified incident-response runbooks.

Engineered mission-critical commerce and ordering backend microservices operating under peak high-throughput transactional loads.

• Architected high-throughput asynchronous order-processing pipelines using Java/Spring and distributed message brokers, decoupling core checkout flows from downstream inventory services.
• Optimized database query performance, distributed caching, and connection pooling across high-volume relational and NoSQL data stores.
• Drove engineering excellence initiatives including test-driven development, code coverage gates, and peer architecture reviews.

Built core features, APIs, and automated test frameworks for Sysco’s next-generation digital customer ordering platform.

• Developed RESTful services and customer account management modules integrated with legacy enterprise resource planning (ERP) backends.
• Built automated regression and end-to-end integration test suites, preventing regression leaks across bi-weekly continuous delivery cycles.
• Collaborated with international engineering and product teams across the US and Sri Lanka to establish unified interface contracts.

Developed open-source automated testing frameworks and serverless cloud prototypes.

• Contributed to CodeSpec, an open-source BDD test automation framework integrating C#, Selenium WebDriver, and Appium for mobile and web validation.
• Engineered early serverless prototypes with React, AWS Lambda, Cognito authentication, and DynamoDB.
