Staff augmentation · remote
Staff augmentation should mean named engineers in your GitHub, not a résumé lottery or a vendor with a fake Zurich or London address. CodeLoop Studio embeds iOS, Android, Flutter, and React Native developers with UK, DACH, and EU product orgs — your Slack, your stand-ups, CET overlap, English delivery.

Staff augmentation (this page): one or more seniors join *your* process after a repo audit — your tickets, your stand-ups, your roadmap. Dedicated team on hire a developer: a 3–4 person mobile/web pod that still embeds, but is scoped as a capacity package. Project / MVP: CodeLoop owns a milestone end to end — discovery through store — see MVP development or custom mobile app development.
We say which model fits before we staff. Nearshore hours and honesty: nearshore for UK and EU. Half-finished repos need legacy software takeover first. Scoped React Native builds: React Native app development.
Kickoff is a short audit of the repo, the store accounts, and the next release. Then we work in your tools: GitHub, Linear, Figma, Slack or Teams. Native Swift and Kotlin when the experience must feel platform-perfect. Flutter or React Native when one engineer should ship both stores. We will not silently rewrite the app unless that is the brief.
UK and EU teams share almost the full workday. CET is typically one hour ahead of London and the same clock as Amsterdam or Berlin. US East Coast teams get live conversation in the ET morning, then async updates. Remote from Sarajevo is cheaper than a local NYC or London squad at the same seniority. That is the point, and we say it. Typical mobile work takes 3–9 months from idea to launch; staff-aug can start faster. NDAs are standard for fintech, health, and unannounced products.
Hiring remote mobile app developers for staff augmentation should not mean a marketplace of strangers or a vendor that pretends to sit in your city. CodeLoop Studio is a software team in Sarajevo. We embed iOS, Android, Flutter, and React Native engineers with US, UK, and EU product teams — on your GitHub, in English, on hours that overlap.
There is no US or UK office. We say it here so procurement is not surprised. London-specific delivery is mobile app development for London teams. New York overlap is mobile app development for New York teams. A full product build — not only a seat — is custom mobile app development.
A named owner
Not a contractor who vanishes when the sprint ends. QA sits behind the engineer. The studio is accountable.
Your tools
GitHub, Linear, Figma, Slack or Teams. We embed. We do not force a mystery methodology.
UK / CET day
Live stand-ups with London and EU teams without late-night calls. One hour of offset, not twelve.
ET morning window
When New York is starting the day. The rest is written: tickets, recordings, status you can read before standup.
NDA-ready
Fintech, health, unannounced products. Standard. We will not treat confidentiality as a surprise clause.
Stay for OS updates
Staff-aug can start faster than a 3–9 month product build. After launch we can remain. We do not vanish.
A
One senior in your repo after a short audit. Native Swift and Kotlin when the experience must feel platform-perfect. Flutter or React Native when one engineer should ship both stores. We will not silently rewrite the app unless that is the brief.
B
A small team that owns a milestone: MVP, store launch, a painful native module. Same people, different contract. Typical product work still sits in the 3–9 month band when you want an app delivered end-to-end.
Repo, store accounts, next release. We say whether we fit — and whether a rewrite would be malpractice.
Seat or workstream. Overlap hours we can commit. Written in the estimate, usually within 24 hours of a brief.
Your stand-ups, your tickets. Remote from Sarajevo is cheaper than a local NYC or London squad at the same seniority. That is the point, and we say it.
| Fact | What we will stand behind |
|---|---|
| Studio | CodeLoop Studio, Sarajevo. No US, UK, Swiss, or German street we do not occupy. |
| Models | Dedicated developer in your process, a 3–4 person mobile/web pod, or a studio-owned MVP or store launch. Estimates within 24 hours. |
| Overlap | UK and CET share almost the full workday. US East Coast: ET morning live, async written updates after. |
| Stacks | Swift/Kotlin, Flutter, React Native. We work inside your tickets — we do not force a mystery methodology. |

Where is the team?
Sarajevo, Bosnia and Herzegovina. No invented US or UK street.
Do you need an on-site entity?
If yes, say so before discovery. We will not waste the call. Most teams hire us because the work is remote-first anyway.
Which overlap do you need?
UK/CET day or ET morning. Send the brief from hire a developer or the product pages above.
Sarajevo, Bosnia and Herzegovina. There is no US or UK office. We say it here so procurement is not surprised. The work is remote-first: your tools, your repos, overlap hours.
Yes. We audit the codebase, then embed one senior engineer or take a workstream. We will not silently rewrite your app unless that is the brief.
Yes. UK and CET clients get a normal workday with a one-hour offset at most. US East Coast clients get ET morning stand-ups and written updates async for the rest of the day.
Both. Some teams need a dedicated developer in their process. Some need a studio to own an MVP or a store launch. We say which model fits before we staff. Estimates come back within 24 hours.
Yes. A small pod that owns a workstream, or several seniors in your Slack. Nearshore hours (CET) are the point. Monthly cost is a written range after roles — we do not put a fake day-rate on this page. Start at /hire-developer.
Yes. We embed in your GitHub, Jira or Linear, and stand-ups — Zurich and Berlin teams get CET overlap without pretending we sit on Bahnhofstrasse. Typical ask: one senior or a 3–4 person pod for mobile and web. Audit first, then your process. See /hire-developer for role-specific paths.
Yes — team extension in English with CET overlap. Delivery language is English; German UI from your copy. Hub: /hire-developer. Nearshore honesty: /nearshore-software-development.
Nearshore from Sarajevo: same craft culture, lower unit cost than a local London or Zurich squad at the same seniority. You get a named owner and QA behind the engineer — not anonymous CV rotation. Context: /nearshore-software-development.
Yes. We embed iOS, Android, Flutter and React Native engineers, and Next.js engineers for the web admin or product surface, in the same team — your tickets, your stand-ups, your Definition of Done.
After a short audit of the repo, the store accounts and the next release. We confirm the start date and the named engineer in writing once roles are clear.

Nearshore for UK and EU
UK scale-ups shortlisting the best nearshore software development companies in Europe usually want a similar time zone, good English, and rates below London agencies — not a letterbox in their city. German Mittelstand teams ask the same: Osteuropa or Balkan partner, shared workday, fair rates. CodeLoop Studio is that studio in Sarajevo, Bosnia and Herzegovina. We ship mobile apps, web products, and dedicated squads remotely. We will not rent a Shoreditch or Mitte address and call it headquarters.
Legacy software takeover
When a freelancer leaves a half-finished Flutter or React Native app with messy code, you need a European partner that takes over existing or legacy apps, runs a code audit, and continues development — not a six-month rewrite sold as modernisation. CodeLoop Studio in Sarajevo joins Flutter, React Native, native, or Next.js repos when access and ownership are real. We will not invent a London or Berlin office to win the RFP.
Custom mobile apps
You need a custom mobile app that can pass App Store and Google Play review, survive the next OS release, and get used more than once. CodeLoop Studio designs and builds native and cross-platform apps for startups and companies that want a product team, not a pile of screenshots. Stack choice comes after we see the product — this page is how we engage, staff, and ship.
London teams
If you searched for a studio to build a custom mobile app in London, you do not need another vendor with a Shoreditch coworking photo. You need a team that ships iOS and Android, speaks product English, and is on a call during UK working hours. CodeLoop Studio is based in Sarajevo and works with UK companies remotely — including product teams in London.
Dedicated team in Europe (blog)
A dedicated development team in Europe should show up in your GitHub and stand-ups — not on a slide with a mailbox in a city you never visit.
Nearshore vs offshore 2026 (blog)
Nearshore is not a rebranded offshore slide. For UK and EU buyers it is overlap, English delivery, and saying where the team actually sits.
