code you cancount on.
4CS is a software studio, covering different corners of computer science. We design, build and run software products end to end.
The studio
01 / 04
Most agencies deliver code. We deliver reliability.
Every 4CS project gets the dedication of our core engineering team. We don't do department hand-offs, and there are no account managers acting as middlemen. The people you talk to are the ones actively writing, deploying, and monitoring your code.
We keep the surface area small on purpose: a tight crew, a proven stack, and full ownership from the first whiteboard sketch to the server it runs on. Small by design. Precise by habit.
Capabilities
02 / 04
Web platforms
Multi-tenant SaaS, dashboards, APIs and integrations. Built on .NET and modern React / Next.js, engineered for the long run.
Mobile
Native-quality apps for iOS and Android from a single codebase, shipped and maintained through both stores.
Cloud & DevOps
Docker, CI/CD pipelines, cloud and VPS infrastructure, monitoring and zero-downtime deploys. Your product, actually running.
Data & AI
Data pipelines, reporting and LLM-powered features — embedded where they earn their keep, not bolted on for show.
How we work
03 / 04
Discover
We map the problem before touching a keyboard: goals, constraints, data, and the one metric the project must move.
Design
Architecture and interface take shape together — a system diagram and a clickable surface you can react to early.
Build
Short cycles, working software every week, and a staging environment you can open from day one.
Run
Deploys, monitoring, backups and iteration. We stay on after launch, because launch is the starting line.
