Engineering with Intent, Precision & Craft

I am Sahil Langoo, a Full Stack Systems Engineer at Eresolution Consultancy Services & Co-Founder at SquadCoders based in Kashmir, India. I hold a Bachelor of Technology in Computer Science Engineering (CGPA: 7.07, Capstone: Listify) from the University of Kashmir and a 3-Year Diploma in Computer Science Engineering from Kashmir Govt Polytechnic.

My engineering philosophy is rooted in minimalism: building software that is fast by default, respectful of user resources, and designed with zero unnecessary runtime bloat. I prioritize static generation first, minimal client-side JavaScript, and strict end-to-end type safety.

Across Eresolution Consultancy Services, SquadCoders, and Taffin.Tech, I have engineered high-concurrency Cloudflare Worker API gateways (Hono, Meta CAPI, Turnstile), Go REST microservices (Chi, Huma v2), full-stack platforms (Rooh Yaseen, Hotel Akbar Sonamarg, HackerForce), and comprehensive telemetry pipelines (Google Search Console, GA4, Clarity, Sentry).

Core Operating Principles

  • KISS & YAGNI

    Simplicity over premature abstraction. Build what is needed with precision and zero unnecessary dependencies.

  • Performance by Default

    Static HTML generation first, Partytown worker offloading, zero main-thread block, 0.00 CLS, and instant global TTFB.

  • Tactile UI Craft

    High-contrast typography, calibrated OKLCH color systems, and responsive micro-interactions (scale on press, smooth scroll).

  • Type Safety & Quality Gates

    End-to-end type safety, Zod runtime schema validation, and automated build-time link and asset verification.
