Abhishek Thakur.

I build SaaS platforms and payment systems. Most recently led engineering at Bizdesire on Uplevelit. Open to new senior / staff roles, remote, global.

Selected work

Things I've shipped.

Three case studies from the last few years — the products live, the stacks real, the trade-offs honest.

  1. 01

    Uplevelit

    An Experience-as-a-Service marketplace — 1:1 sessions, group classes, livecourses, and direct Q&A with operators who earned the knowledge in the field.

    • TypeScript
    • React
    • Firebase Functions
  2. 02

    Penbook

    An AI-powered platform that brings readers and writers together — write with AI tools, read in a connected universe, share, and join book clubs.

    • Node.js
    • NestJS
    • MongoDB
  3. 03

    Rocket Rebates

    Search local rebate programs, generate detailed reports with AI, and assemble admin-reviewed submission packages — end to end.

    • Node.js
    • NestJS
    • PostgreSQL
What I do

Where I spend my time.

01

SaaS Platforms

Multi-tenant architectures with RBAC, subdomain routing, and tenant-level data isolation.

02

Payment Systems

Stripe subscriptions, wallets, payouts, refunds, and webhook handlers with idempotency.

03

Cloud & AI

GCP deployments via Docker + GCR. OpenAI integrations with streaming and token budgeting.
