## Background & Engineering Intent

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.

## Daily Tools & Technical Arsenal

- **Languages & Runtimes**: TypeScript, JavaScript (ES2023+), PHP, Typst, Go, Python, Node.js, Bun, HTML5, SQL.
- **Frameworks & Architecture**: Astro 7.3, Next.js, React, Hono, Huma v2, Chi, Cloudflare Workers, Partytown.
