I build reliable backends — and the AI-agent infrastructure that lets teams ship them autonomously.
5+ years across the full product lifecycle, from IC to engineering lead. I design before I build — invariants, domain models, and API contracts come first. That’s also what makes AI coding agents ship production-grade code instead of guesses.
No pitch — we’ll scope your problem and see if I can help.
› How I can help
Three ways teams bring me in
Every engagement starts with a call to scope the problem — pricing follows from there.
Architecture & design review
A senior second pair of eyes before you scale
I map the invariants, domain model, API contracts, and failure modes of your system, then hand you a prioritized risk-and-fix plan.
- Domain model & invariants written down, not assumed
- API contracts and module boundaries reviewed
- Concrete, prioritized list of risks and fixes
AI-agent infrastructure
Make AI coding agents ship production code, not guesses
Docs-as-runtime context systems, agent governance and routing, and machine-readable specs that close the gaps which cause hallucinations.
- Domain model, invariants & contracts as machine-readable context
- Multi-agent governance: trust levels and routing contracts
- Specs that let agents reason about your architecture autonomously
Fractional eng lead / build
Own delivery end to end, or lead a small team to
From greenfield products to specific subsystems — auth, billing, workflows. I design, build, and ship, and set up the process so the team keeps shipping.
- Greenfield product or subsystem, zero to production
- Sprints, code review, staging→prod pipeline stood up
- Predictable delivery with product and business stakeholders

Problems, and what changed after
A few systems I've designed and shipped — framed by the outcome, not the tech. Some details are anonymized where work is under NDA.
Authorization at scale
Authorization at scale for a multi-tenant SaaS platform
A Google Zanzibar-style ReBAC system with sub-millisecond checks and a whole class of misconfiguration bugs designed out.

Reliable money flows
Metered billing as durable, auditable workflows
Plan management, quota enforcement, usage aggregation, overage pricing, and invoicing — built as durable Temporal workflows that survive failure.

AI-agent infrastructure
SignatureDocumentation-as-runtime for AI coding agents
A machine-readable context system and multi-agent governance layer that let AI coding agents reason about a real platform and ship production-grade code.

Zero to production + leadership
A greenfield assessment platform, and the team to build it
Built and led a 6-engineer team from scratch and shipped the company's core assessment product to production in under three months.

› About
Hi, I’m Atif.
I’m a software engineer who’s spent 5+ years going from intern to engineering lead and back to deep technical ownership — because building the thing is what I love most.
I design rigorously before I build: I want the invariants, the domain model, and the API contracts pinned down before a line of code. That habit is why the systems I ship hold up — and why I can point AI coding agents at a codebase and trust what comes back.
I work remotely with teams anywhere. I care about clear communication, predictable delivery, and leaving your codebase better documented than I found it.
