Yash Sharma

Full Stack Engineer · sole owner of the platform rebuild

Dec 2025 – Present · Contract · Singapore

Sole engineer on the modernization of a legacy enterprise content-delivery platform serving hundreds of customer-managed Android terminals. Owned it end to end: architecture, backend services, frontends, cloud infrastructure and delivery to the client.

• Led solution design for the Delphi-to-Go migration and executed it: decomposed the legacy monolith into containerized Go microservices and shipped 90+ REST APIs behind a stable contract the client's devices and CMS depend on.
• Built the template-based Vue.js CMS the client's operators use to author and schedule content, and the offline-capable Android player that consumes it, so the two ends of the system were designed together.
• Engineered for unreliable field conditions: resumable 5 GB uploads, encrypted real-time content delivery, and a player that keeps running through connectivity loss. Sustained the client's SLA across hundreds of terminals.
• Ran the platform on Kubernetes across AWS and Huawei Cloud: containerization, deployments and CI/CD, with services isolated so a failure in one path never took down content delivery.
• Cut repetitive engineering and delivery effort by building AI agents and automation with MCP tooling, Zapier and n8n, and applied AI-assisted development across authoring, refactoring and code review.
