A full-stack developer owns a change from database table to screen

No, and hiring one as a cheaper pair usually disappoints. The job is ownership across the boundary: the contract between screen and API, the data behind it and the release. What that buys is fewer features waiting while two people finish their halves, not twice the depth on either side.

When one side keeps becoming a project of its own: the interface needs a design system shared by several apps, or the backend needs data or integration work that cannot fit between features. Teams then usually keep full-stack developers on product features and add a frontend or backend specialist for that side.

Often, because TypeScript on both ends lets the screen and the server share types: React or Next.js in the browser, Node.js on the server and PostgreSQL underneath. It is not the only pairing. Our engineers have shipped Next.js in front of Python and FastAPI, and React in front of .NET. The developer works in what your product already runs.

For a small product on managed hosting, yes: one pipeline to production, error alerts and a rollback the developer has already practised. Once you run your own cluster, several environments or an on-call rota, that becomes DevOps work, and we would rather add a DevOps engineer than stretch one person across both.

Often, if the scope is cut to the path your first users take. One developer can carry sign-in, the core records, the screens and deploys for a first release, and our engineers have joined client teams to get MVPs out within a fixed timeframe. If the plan also needs a mobile app, heavy data work or a design system, we will say it needs more than one person.

Making it runnable and traceable. The developer first gets it building from a fresh clone, then maps which endpoint and table sit behind each screen and writes that map into the repository. Feature work continues meanwhile: each change starts with the part of the map it touches, so knowledge grows where the roadmap goes.

The risk is real with one person, so the work is set up to survive it. Decisions are written into the repository as they are made, every change has tests and a description, and nothing lives only on the developer's machine or personal accounts. If a developer does leave, the contract's notice period leaves time for a handover to whoever comes next.

Feature by feature rather than layer by layer. Each finished change is shown working, from its screen to its data, instead of separate frontend and backend tickets closed on different days. Every pull request carries its migration, endpoint and screen together, so the history of your repository reads as a list of features.

Yes. Many clients start with one senior engineer to cover a specific capability or capacity gap, then add specialists only when the roadmap requires them.

Yes. Adding an engineer follows the same route as the first, and you interview them. Reducing the team follows the notice period agreed in the contract, and the work is handed over in your repository before anyone leaves.

Yes. You manage priorities and day-to-day work directly, in your own channels and delivery process.

Yes. You interview every candidate using your own process and make the final decision about who joins the team.

Our engineers are ImproveIT employees and long-term contractors working through our teams in Poland and Ukraine. We are not a freelance marketplace and do not resell developers from other vendors.

Replacement terms are defined in the contract upfront, so it does not become a negotiation.

You do. IP assignment is included in the contract, and we can sign an NDA before discussing the project.

We sign an NDA before discussing the project, and confidentiality and IP assignment are part of the contract. Engineers work in your repositories, cloud accounts and tools with the access your team grants, so you can narrow or revoke it at any time.

Yes. Our engineers work with teams across Europe and the US. We agree the required working-hour overlap before matching candidates.

Our developers work in English with international product and engineering teams every day. English level is included in the candidate information you receive before the interview.

Rates depend on the role, seniority, experience, and engagement model. You receive the rate, availability, and candidate profile in writing before making any commitment.

Both are agreed before the engagement starts and included in the proposal and contract. We are flexible in that and usually agree on the terms suitable for a client.
