About this gig
Need a SaaS MVP, AI SaaS or custom web app built right and shipped? You're in the right place.
Most MVPs never make it to production. Yours will.
I'm Tushar, a CTO and full stack web developer. I personally design the architecture of every app, then write the code myself.
Zero to 30,000 visits a month across two products I built and run. My code is merged at Expensify (Nasdaq, 10M+ users), a Featured Client here.
WHAT I BUILD
- SaaS MVP and AI SaaS app development in Next.js, React, Node.js, PostgreSQL, Supabase
- Custom web app: auth, payments, admin panel, dashboards, client portal
- AI features: AI chatbot, RAG over your docs, Claude and OpenAI
- Fix and finish your Lovable, Bolt or Cursor build
MY APPROACH: SCOPE, BUILD, LAUNCH, SCALE
Fixed quote in 1 hour. Daily updates on a staging link. Launch with the core features, then grow what your users actually use.
WHAT CHANGES FOR YOU
- You stop explaining your idea and start showing it
- You never wonder if your developer disappeared
- You own the source code, in your repo, from day one
Just send your idea, even one line. I reply within 1 hour.
Message me before order.

Zero to 30,000 visits a month on pure automation: an agent researches, writes and publishes every morning, and I approve it once. That's my own product, built end to end.
My code is merged at Expensify, a Featured Client here. Primary engineer on a public post-quantum protocol, 990+ commits. CTO, 8 years building software.
I build SaaS MVPs and AI web apps in Next.js, React, Node and PostgreSQL, AI agents and automations that run daily, and I rescue apps built fast in Lovable, Bolt or Replit. Auth, payments, admin, RAG chatbot, deployed, source in your repo.

FAQ
Do you work with an existing or vibe-coded app?
Yes. Send repo access or the Lovable, Bolt, Replit or Cursor project link. I review the code, list the fixes, quote a fixed price, and take it to production.
What do you need from me to get started?
One paragraph on who uses the app and what it does, any designs or a repo, and your deadline. I reply with a scope and a fixed quote within 1 hour.
Will I own the source code?
Fully. Every package includes the source code, delivered in your GitHub repo with handover docs. No lock-in.
What if I do not have designs yet?
I design as I build with a clean component system (Tailwind, shadcn). If you have Figma, I convert it to Next.js pixel-perfect.
Can you build an AI chatbot with RAG over my data?
Yes. Claude or OpenAI, retrieval over your documents, database or site, with citations and a fallback. Included as the AI feature in Standard and Premium.
How long does a full MVP take?
Standard delivers a working MVP in 14 days, Premium a full SaaS in 21. Faster delivery is available as an extra on every package.
Do you provide support after delivery?
Yes. A support window after launch is included, and the Extra Support add-on covers 30 days of fixes, tweaks and monitoring.
How is the final price decided?
Packages cover the common scopes. Anything custom gets a fixed quote after a short scope call, before any work starts. No hourly surprises.
Do you sign NDAs?
Yes, yours or mine, before you share anything sensitive.
Which hosting do you use?
Vercel, AWS, DigitalOcean or your own VPS with Docker and SSL. Deployment is included in Standard and Premium, and available as an extra on Basic.
