We add AI to existing apps, build SaaS and MVPs end to end, and take over apps that keep breaking.

LLM features, chat, document AI, and agents, built into the app your users already use. Invoice AI reads scanned and handwritten invoices without per-vendor templates. TrueCert suggests answers across a long certification form and checks them before it is submitted.

Auth, payments, and deployment done properly, not bolted on at the end. CuePilates went from idea to a paid launch in under a month, with Stripe subscriptions and an AI class planner behind it.

Someone else built it and now it falls over. We take over the code, find what is actually wrong, and make it stable. In one job we took over two live apps for one client and made them stable, one right after its production database was wiped.
Products we built and took to production. Each one has its own page with the details.
AI platform
A clinical AI platform built for doctors who practice traditional Korean medicine. A multi-model LLM engine drafts SOAP reports and clinical documentation from visit recordings and consultation inputs, while doctors manage patient records, scheduling, and herbal formulation tracking in one workspace. The interface is Korean-first and uses the correct domain terminology instead of translated Western medical terms. It is in production and used by doctors in Korea.
“I worked with Zeeshan on multiple AI-driven healthcare applications, and he was a reliable and highly capable development partner throughout. Strong ownership, clear communication, and a solid understanding of product goals beyond just implementation. I would recommend him to any team as a true product partner.”
“Zeeshan took my vision for CuePilates, a fully AI-powered Pilates class planning platform, and built it into a real, live product with paying subscribers. He handled Supabase, Vercel, Stripe, the Anthropic API, auth, and security hardening. I came in with zero coding background, and he translated my ideas into real features, milestone after milestone. If you need a developer you can actually trust, Zeeshan is your guy.”
Workflow automation
An AI certification platform that replaced spreadsheets and site visits for a recycling company.
“We highly recommend Zeeshan for AI-related development work. He built an AI agent for our certification support system, delivering high-quality results with efficiency and professionalism. Proactive, responsive, and a pleasure to work with, an asset to any team.”
Mobile app
A diet app live on the App Store and Google Play, with a doctor dashboard behind it.
LLM integration
Multi-model report generation (GPT, Claude, Gemini) with automatic provider fallback.
Document AI
OCR and AI extraction from scanned and handwritten invoices, with a human review step.
“Working with Zeeshan on the invoicing AI project was a highly collaborative and innovative experience. Zeeshan brought a deep understanding of AI model development and integration, while I focused on aligning the solution with real-world invoicing workflows and compliance requirements.”
App rescue
Two live apps for one client, taken over and made stable, one right after its production database was wiped.
No surprises on scope, price, or who owns the result.
Zeeshan is a full-stack AI engineer with a B.S. in Artificial Intelligence, Top Rated Plus on Upwork with a 100% Job Success score.
On larger builds Zeeshan works with a small team and stays accountable for what ships. You deal with the person who writes the code, not an account manager.
See Zeeshan’s own portfolio at r-zeeshan.devFixed price per milestone. We scope the work after we understand the product, so you know the number before we start. No surprise invoices.
Usually, yes. We read the code and tell you straight: what is worth keeping, what needs to go, and what it takes to make it stable. No sales pitch, just the honest read.
Yes. It is one of the three things we are usually hired for. We read the code and the infrastructure first, tell you what is wrong, and fix what breaks in production before adding anything new. We have taken over live apps and made them stable, including one right after its production database was wiped.
We build with secure, encrypted data handling from the start. We don’t claim compliance certifications such as HIPAA or SOC 2. That is not something a developer hands you. Where you need a compliance specialist, we’ll tell you so you can bring the right person in.
No. You own all the code and get a clean handover with documentation, so anyone can pick it up later. If you want us to keep running the product after launch, that is a separate monthly retainer. You do not need one to own your product.
