We are a software engineering company that designs, builds and supports custom systems — firmware on embedded boards, the platforms that control them, and the web and mobile apps people use every day.
TTARSCI is an independent software engineering team. We work across the whole stack: C and C++ on embedded Linux and RTOS targets, Python and .NET services, and React / Next.js front ends. We take a product from a written requirement to a running, tested, documented system — and we stay to support it.
Our mission: To build software that is safe to rely on: traceable from requirement to code, tested before it ships, and clear enough that our clients can own it after we hand it over.
TTARSCI started with embedded and broadcast software — code that has to run for years on a fixed piece of hardware without anyone watching it. That discipline shaped how we build everything else. Today the same team delivers embedded control platforms, construction and engineering tools, finance and analytics software, and consumer web and mobile apps, using one consistent way of working: staged delivery, requirements traceability and automated testing.
We decide on evidence — measurements, tests and specs — not on fashion.
Hardware, money and personal data are guarded by clear boundaries, audit trails and least privilege.
Short demos, honest status and written decisions. No surprises at the end of a sprint.
Every project ships with documentation, tests and a runbook, so you are never locked in.
Founder & CEO
Denis founded TTARSCI in 2010. He studied Computing for Real-Time Systems at the University of the West of England, covering both computer hardware and software, and began his career in 2008 as a field test engineer at Digital TV Labs in Bristol, testing digital TV technology in real-world conditions. He then moved into software quality and testing in the R&D teams of Broadcom and Ericsson, and since 2015 he has worked as a technical consultant. More than 18 years of testing, R&D and consulting work is why TTARSCI treats testing, traceability and real hardware as part of the build, not an afterthought.
From a single driver to a complete platform — we can take on one layer or the whole system.
Bespoke platforms built around your process, not the other way round.
Firmware, board support and on-device agents for ARM targets running Linux or an RTOS.
Fast, accessible React and Next.js sites, PWAs and Android apps.
Software for set-top boxes, head-ends and broadcast workflows.
Architecture reviews, technology choices and delivery plans you can act on.
Test strategy and automation that catch problems before your users do.
We keep systems patched, monitored and improving after launch.
We pick the tool that fits the problem — and we are fluent from bare-metal C to cloud deployment.
A selection of systems we have built. Each case study has an interactive demo that shows the core idea in your browser, using sample data.
Six clear stages. You see working software at the end of every one.
We learn your goals, users and constraints and turn them into written, testable requirements.
Architecture, data model and interface design — reviewed with you before code is written.
Short, numbered stages. Each one ends with a working demo and a commit you can inspect.
Automated unit, integration and end-to-end tests, plus simulators for hardware we cannot reach.
Containerised, documented releases with a runbook and a clean hand-over.
Monitoring, security updates and continuous improvement once you are live.
One team covers firmware, back end and front end, so nothing is lost between layers.
Every feature is linked back to a requirement and forward to a test.
Least-privilege design, audit logs, MFA and dependency scanning are part of the first release, not an extra.
Staged plans with clear exit criteria — you always know what is done and what is next.
Send a short description and we will get back to you, usually within one working day.
