Open to full-stack and backend roles

Rushikesh Jadhav

Full-stack developer · ex-@Gtribe · ex-@Fynd · 2x Hackathon Winner · Marathon runner

I'm a full-stack developer from Pune. I built Gtribe's new website, booking system and admin panel, and it's live at gtribe.in.

Where I've worked

Two internships, both shipping to real customers.

  1. Jun 2026 – Oct 2026

    Pune, Maharashtra

    SDE Intern · Gtribe Experiences

    • Architected Gtribe 2.0 end-to-end from PRD to launch, unifying trek bookings, a gear shop, corporate CRM and GST invoicing for 2 companies under one login
    • Launched it on gtribe.in in Oct 2026, replacing two separate websites (trek booking and a Dukaan gear shop) for a business with 8,500+ trekkers
    • Engineered race-condition-safe seat booking with 15-minute holds; a load test of 200 users racing for 30 seats produced exactly 30 bookings, and the API sustained ~730 req/s with zero errors
    • Built 3-way Razorpay reconciliation (callback, webhook, server verification) with idempotent confirmation, so paid bookings are never lost or double-confirmed
    • Designed a 33-table PostgreSQL schema in Drizzle ORM, evolved through 60 additive migrations, covering bookings, RBAC, quotations and GST-compliant invoicing
    • Implemented server-enforced RBAC with per-area permissions, hiding financial data from unauthorized staff at the API level
    • Automated WhatsApp OTP login and 21 Meta-approved notification templates through a BullMQ queue (10 msg/s with retries, deduplicated so no message is sent twice)
    • Set up CI/CD with GitHub Actions: tests gate every deploy, migrations run automatically, and a failed health check rolls the API back on its own
  2. Aug 2025 – Jan 2026

    Mumbai, India

    SDE Intern · FYND

    • Resolved client-raised Jira tickets daily, ensuring fast turnaround on customer-reported issues
    • Worked directly with clients to resolve issues and help them adopt product capabilities
    • Reviewed release PRs for FYND's Docusaurus docs and deployed static sites as Azure Static Web Apps
    • Integrated frontend and backend systems through API pipelines, improving data reliability by 70%
    • Improved API reliability and payload handling, reducing support turnaround time by 60%

Things I've built

Production systems, hackathon builds and AI experiments, each one shipped end to end.

Gtribe 2.0

A unified adventure-tourism platform: trek bookings, gear shop, CRM and GST invoicing for two companies, built solo from PRD to launch.

About me

I finished my B.E. in Computer Engineering in 2025. At Gtribe, I built their new platform: trek bookings, the gear shop, payments and GST invoices, all in one place. It went live in October 2026. Before that, I interned at FYND, where I fixed customer issues and worked on their docs and APIs.

I enjoy backend work the most: databases, payments, and making sure things don't break when lots of people use them at once. Outside work, I run marathons, go to the gym, and sometimes write or make videos about what I'm building.
