Software Development Services
alien-dev is the studio name of Elmaz Nikšić, a software engineer with over nine years of production experience. These are the engagements we take on, each backed by work that has already shipped.
AI Integration & LLM Development
AI features that survive contact with production.
We add AI to products that already work. That means model integration wired into a codebase somebody is already depending on — prompt and tool-calling pipelines, endpoints kept behind one swappable interface, and evaluation that tells you whether the feature got better or only got newer. The interesting part of an AI feature is rarely the model. It is everything around it.
Explore this service →Dedicated Engineer & Team Extension
An engineer who joins your team, not a stranger an agency sent.
Sometimes the thing you need is not a project with a scope document. It is one more engineer in standup, reviewing pull requests, holding context across quarters. This is that: long-term embedded work inside your team, your board and your release process — contracted directly, with no account manager in between.
Explore this service →React & Next.js Development
React frontends that stay fast as the product grows.
We build and rebuild React frontends for products that have outgrown their first version. That means Next.js applications rendered on the server, component libraries a whole team can share, and interfaces that hold up under real traffic instead of only on a designer's machine.
Explore this service →Node.js Backend & API Development
APIs that hold their shape under load.
We design and build Node.js backends: the REST APIs your frontend depends on, the data models underneath them, and the boring reliability work — validation, rate limiting, error handling — that decides whether a service survives its first busy week.
Explore this service →Full-Stack Web Application Development
One engineer accountable from the database to the button.
Some products do not need a frontend team and a backend team and a coordination overhead between them. They need one engineer who can model the data, build the API, build the interface, and take responsibility for the seam where those meet — which is where most projects actually go wrong.
Explore this service →React Native Mobile Development
One codebase, both stores, no second team.
We build cross-platform mobile applications in React Native — a single TypeScript codebase that ships to both the App Store and Google Play, with the backend and real-time infrastructure behind it built to match.
Explore this service →Web Performance Optimisation
Measured before, measured after, or it did not happen.
Performance work only counts when the numbers move. We profile the application as it actually runs, fix what the measurements point at rather than what feels slow, and re-measure — on the frontend, the backend, and the queries underneath both.
