Applications & APIs
Web apps, APIs, websites, and data platforms — architected to handle real traffic, real data, and real edge cases.

01 / Build
AI Build.
Production-grade applications, APIs, websites, and data platforms — built on 21 years of engineering, with Claude as the velocity multiplier. Senior judgment, reviewable code, real observability. From MVP to a multi-quarter engagement.
Why build with me
Most AI projects die in the gap between a demo and production.
A prototype that works in a notebook isn’t a product. The hard part is everything after the demo — reliability, evals, observability, security, and a deployment pipeline you can trust. I build software that ships to real users and keeps working, with the same engineering discipline a serious product deserves.
What you get
Software built to run, not just to demo.
01 / Reviewable code
Code you can read
Clean, documented, and yours — every change ships through a reviewable pull request. Not raw model output piped to users.
02 / Observability
You can see it run
Logging, tracing, evals, and alerting built in — so when something moves, you know about it before your users do.
03 / CI/CD
Continuous delivery
Every merged change ships to production behind tests and evals that catch regressions. You see progress as it happens, not at the end.
04 / Senior judgment
21 years of decisions
Architecture and trade-off calls made by someone who has shipped and maintained production systems for two decades — not a junior team.
05 / Clean hand-off
No lock-in
Documentation, runbooks, an on-call playbook, and a working session with your team. Code that outlasts the engagement stays with people who can change it.
Use cases
What I build — running in production.
Not slideware. Each of these is live and built the same way client work is.
00 / Apps & APIs
AI in your product
Claude and adjacent models embedded into user-facing products — production-grade integration, not a chat widget glued on top.
01 / Document intelligence
Structured data from documents
Extract structured data from contracts, invoices, and forms.
02 / Observability
Production AI you can trust
Monitoring, evals, and tracing — so you know what the model did, why, and what to do when it drifts.
How it works
Scoped up front. Shipped continuously.
No surprises, no lock-in — you see working software throughout, not a big reveal at the end.
00 / Scope
Scope it
A fixed-fee SOW with milestones, deliverables, IP terms, and clear exit conditions — written before any code is.
01 / Ship
Ship it
Continuous delivery against the milestones. Every merged PR ships; evals catch regressions; you watch it come together.
02 / Hand off
Hand it off
Docs, runbooks, and a working session so your team owns what was built — with the IP and the knowledge to change it.
Investment
Fixed-fee milestones. You see progress, not invoices.
Every engagement is a scoped statement of work with clear deliverables and exit conditions agreed before any code is written. You pay per milestone, as working software is delivered — progress you can see, not a meter that runs. You own the IP. Engagements run from a 4-week MVP to a multi-quarter build.
Why ZeroIndex
Founder-led. The senior engineer named in your contract is the one writing the code.
I’m Abhishek — 21 years of software engineering and engineering leadership behind every build. No vibe coding, no junior team: the person who scopes your project is the person who ships it, and the person you can still call when it needs to change.
