Surinder Singh M.

SENIOR BACKEND ARCHITECT & SYSTEMS ENGINEER | 20+ YEARS EXPERIENCE I am a veteran full-stack developer and systems engineer with over two decades of production-grade experience. My core expertise lies in building high-performance backend systems, decentralized applications (dApps), and desktop architectures using Rust and Node.js. If you are looking for an overqualified, highly reliable engineer who can take full ownership of your infrastructure, optimize microservices to slash your cloud bills, or maintain complex legacy applications with zero hand-holding, I am available for long-term monthly contracts at highly competitive, budget-friendly rates. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ VERIFIED OPEN-SOURCE HISTORY & ELITE REFERENCE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ While my Upwork history has been quiet recently, it is because I spent the last several years architecting core open-source infrastructure off-platform. You can review my verified code contributions on GitHub under the Aspectron organization (at github/aspectron and github/surinder83singh), where I co-developed high-performance Rust systems, WASM modules, and browser extensions. My primary long-term client and the founder of Aspectron, Anton, stands fully behind my work and offers this rare guarantee to my future clients: "You can ping me and ask me anything. I am happy to chat directly with your new clients to tell them exactly how Surinder can help them succeed." (Contact details and profile verification available directly upon request via Upwork message). ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ TECHNICAL EXPERTISE MATRIX ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • SYSTEMS & MODERN BACKEND: Rust (since 2020) Node.js (since 2014), WASM32, NW.js, gRPC, Microservices, and API Architectures. • FRONTEND FRAMEWORKS: Google Lit, Polymer, Material Design Lite (MDL), ExtJS, Sencha Touch, jQuery, and AJAX. • ENTERPRISE PHP & CMS (SINCE 2009): Core PHP, MySQL, WordPress, Joomla, OSCommerce, and legacy web modernizations. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ HOW WE CAN WORK TOGETHER ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Whether you need a brand-new system built from the ground up, a memory-safe Rust/NodeJS refactor, or a steady retainer engineer to keep your business-critical web apps running smoothly, let's schedule a brief 10-minute call to discuss how I can bring immediate stability to your team.
