Discovery Sprint
For a new product build that needs scoping. We pin down architecture, scope, and a realistic plan before any code ships.
You've closed pre-seed to Series A and have an AI product to ship. Add senior engineering capacity without trading away code quality or delivery discipline.
A quick fit check before either side spends time on a call.
The teams we fit best already have product pressure, investor expectations, and a real roadmap to ship.

Start with the smallest engagement that resolves the next engineering decision.
For a new product build that needs scoping. We pin down architecture, scope, and a realistic plan before any code ships.
Fixed-scope delivery, typically after a Discovery Sprint has pinned down the spec.
For Series A+ companies with evolving roadmaps: an embedded senior team that flexes with your priorities.
For projects a previous vendor left broken or behind schedule, or for vetting what you already have. Opens with a written review of what you have and a plan for what to build next, then we stabilise the codebase and get it shipping again.

A custom checkout and payment platform for Shopify merchants: gateway integration, Apple Pay and Google Pay, multi-store installs, disputes and settlement reporting.
9 stalled pull requests and a 3-week bug backlog cleared; 3 held features then shipped.
A Shopify app that inverts order entry for live sellers: scan the product, and the draft order builds itself.
30+ SKUs scanned into one Shopify draft order; the old version choked on large ones.
A 60-second skin scan on a pharmacy shelf that resolves into one of more than a thousand personalised formulas, handed to the customer the same visit.
1,000+ skincare formulas resolved from a 60-second phone scan in 55+ San Pablo pharmacies, before the customer leaves the store.
For most funded startups, the right starting point is either a Project Rescue (if code already exists) or a Discovery Sprint (if you’re ready to commit to a build). Either way it opens with a written review. A Phased Build follows once scope is locked. Ongoing Product Engineering makes sense once Series A growth calls for a team that stays with the product.

From the founder
I started Robust Devs in 2019 after watching too many good products die between agencies. The pattern was always the same: big promises in the sales call, silence by week six. We built this firm to be the opposite of that. A small senior team, honest scope, and the uncomfortable truth delivered early.
If you are building in marketing, healthtech, or fintech, tell me what you are working on. If we are not the right team for it, I will say so on the first call and point you somewhere better.

Tayyab Hanif
CEO, Robust Devs
Anything sub-$15K routes to a written review of what you have; it’s the cleanest way to get value fast. Larger scopes move into a Project Build, usually after a Discovery Sprint.
No sales team, no SDR loop. Speak directly with engineers who have shipped AI products to production.
