Ways to engage
Pick the shape that fits your workload.
Dedicated Developer
One senior mobile engineer, full time on your app and nothing else.
- Full-time focus on your iOS and Android roadmap
- Works in your repo, your board, your release process
- Daily standups inside your timezone window
- Senior code review from our side on every PR
- Release management through both app stores
Part-Time Block
A fixed weekly block of mobile hours for maintenance and steady feature work.
- Reserved weekly hours, same engineer every week
- Store submissions, OS updates, and crash fixes handled
- Overlap window with US and UK hours
- Monthly report of shipped work
Project-Based
A scoped app build from first screen to store approval, with a clean handoff.
- Fixed scope agreed before work starts
- Milestone builds on your device via TestFlight and internal tracks
- QA pass on real devices before submission
- Documented handoff, your accounts, your keys, your code
How we vet
Five stages before anyone touches your code.
Portfolio and store review
We look at apps the candidate has actually shipped: store listings, crash-free rates where available, and the code behind them.
Technical interview
A senior engineer probes navigation, state, offline behavior, and platform differences between iOS and Android. Production questions only.
Paired build exercise
The candidate builds a real screen with real API data alongside one of our engineers, including handling the unhappy paths.
Communication check
Written and spoken English, async updates, and whether they can walk a founder through a release decision without jargon.
Supervised first sprint
The first two weeks run under senior review. Every PR and every store submission gets a second set of eyes.
Why us
What you get with WitsCode that a staffing bench can't give you.
Your hours, not ours
We schedule the working day around overlap with US and UK business hours. Standups and release calls happen in your morning, and critical fixes do not wait for the next day.
An engineering studio, not a bench
Staffing agencies rent you whoever is idle. We place engineers who work inside a delivery system proven across 300+ launches: code review, device QA, and release checklists that catch problems before your users do.
Senior skill, sensible cost
India-based senior mobile engineers cost a fraction of the equivalent US or UK hire. You keep the seniority and the process discipline. The only thing that changes is the geography.
Frequently asked
Questions before you reach out.
Most mobile engagements start within three to five business days of a signed agreement, because we match from a bench of engineers already vetted through our five-stage pipeline. You share the codebase or the product brief, interview the profile we propose, and the first sprint starts the same week.
For most products, one cross-platform codebase in React Native or Flutter ships faster and costs less to maintain than two native apps, so that is our default recommendation. We advise native Swift or Kotlin when the app leans hard on platform APIs, heavy animation, or background processing. We will tell you which fits before you commit.
Yes, our engineers handle the full release cycle: certificates, provisioning, store listings, review guideline compliance, and phased rollouts on both stores. Apps ship from your own developer accounts, so you keep ownership of the listing, the reviews, and the ratings history regardless of who does the work.
Yes, every engagement includes a fixed overlap window with US and UK business hours for standups, demos, and release decisions. Focused build time runs in the remaining hours, which in practice means you often wake up to a new build on your device. The window is agreed before the start and does not drift.
You own all of it from day one: source code, designs, backend, and both store accounts. We work inside accounts you control rather than publishing under ours, and the agreement you sign assigns every deliverable to you. If the engagement ends, nothing needs to be transferred because it was always yours.
We replace the engineer at no extra cost, usually within a week, and we manage the handover internally. Shared code standards and documented release processes mean the replacement inherits a working setup instead of a mystery, so your roadmap loses days, not months. You can also scale down with two weeks notice.
