Hey, I'm Vraj — a Full-Stack Engineer from Ahmedabad. I build backend systems that don't break at 3am, APIs that scale, and products that actually ship. Currently crafting things at BACANCY with Node.js, NestJS & AWS.
Things I Probably Shouldn't Admit
I write console.log() everywhere and call it "strategic debugging."
I've named variables data, data2, finalData, and finalDataV2 in the same file.
I once debugged for 2 hours. The issue was a missing comma in a JSON file.
My most-used Git command is git stash — I have 11 stashes I'll "get to later."
I deploy on Fridays and cope by trusting my own tests. It's fine.
Half my TODO comments are from last year. They're probably still valid. Probably.
I open 30 browser tabs for one feature and close them all without reading half.
I've Googled "how to merge objects in JavaScript" at least once this month.

My Story
I'm Vraj — a Full-Stack Engineer at BACANCY Technologies, building production-grade systems since 2022. My work lives at the intersection of clean API design and scalable backend architecture, always with a deep respect for the developer experience on both sides of the contract.
Beyond the terminal, I'm drawn to system thinking — how complex things are made simple, how decisions ripple through architecture, and how great software feels inevitable in hindsight. I graduated from CHARUSAT with a B.Tech in Computer Science, where curiosity for building things became a lifelong discipline.
I believe that an API is a promise — and I take promises seriously. Whether it's a microservice boundary, a database schema, or a deployment pipeline, I care about getting the fundamentals right so everything built on top can move fast and not break things.

Some Of My Featured Project
Lucidium World – Metaphysical Life-Simulation Platform
Launched a full-stack life-simulation platform with AI guidance, tarot, astrology, and gamified engagement supporting 6 user roles (admin, advisor, client, guest, moderator, AI trainer). Authored 40+ modular NestJS API endpoints with PostgreSQL, covering booking, scheduling, notifications, and subscription management across 8 feature modules.
01Mens – Healthcare Consultation Platform
Constructed a HIPAA-conscious backend for doctor-patient consultations handling encrypted chat, video calls, and digital prescriptions for 2 user types. Secured all patient data endpoints using JWT + RBAC, restricting 100% of sensitive medical records to authorized roles only. Automated Stripe subscription billing lifecycle.
02Snot – Pet Learning & Social Platform
Designed a pet social platform with community feeds, short-form video reels, and stories, supporting 4 content types with moderation workflows. Formulated a Tree/BFS-based hierarchical course structure (Module -> Session -> Lesson) enabling trainers to manage 100+ lessons across nested learning paths.
