We own systems. We build systems with partners. We stay after they ship.
An eight-person remote engineering and product team. We build and operate our own systems, engineer commissioned systems with partners, and keep them running after they ship.
Three ways a system reaches production.
Products
Systems we own and operate.
Commissioned Systems
Systems we build with partners.
Production Engineering
Systems we keep running after they ship.
Services
What we can take responsibility for.
A whole product from the idea, or one engineering area inside a product somebody else is building. We own the outcome, not a seat on your team.
Custom Software Development
Red Sentra builds software to a requirement rather than assembling it from a template. The same engineers scope the work, write it and stay with it once it is live.
Application Maintenance & Support
Red Sentra takes over running applications and keeps them running: incidents, production defects, upgrades, deployment and the ongoing engineering a live system needs.
Web Application Development
Red Sentra builds web applications as systems: the architecture, the services behind the interface, the data, the deployment and what happens once real traffic arrives.
Mobile App Development
Red Sentra builds mobile applications together with the services behind them, ships them to a store, and keeps operating them once real devices are involved.
API Development & Integration
Red Sentra designs and builds APIs, and connects systems to the ones that already exist — including the protocols that are hostile, stateful or badly documented.
DevOps & Infrastructure
Red Sentra takes responsibility for the infrastructure and the delivery path a system runs through — how it is shaped, how a change reaches production, and what happens when it should not have.
AI Development
Red Sentra builds AI capabilities into software that has to keep working: the inference path, the services around it, and the rules that decide when the feature is allowed to speak at all.

One sentence in. Sixty nutrients out.
Most trackers stop at calories. NutriSense reads a meal in plain language and records the full picture, then keeps what a watch measured separate from what was eaten.

Four decoders. One socket.
- Decoders
- GigaAM
- Parakeet
- Qwen3-ASR
- Whisper
Pure Rust on Candle with no Python interpreter in the running service. Memory-mapped weights, partial transcripts while the stream is open, and one frame shape out.
- IngestSession state, isolated
- RetrievalGrounded in group history
- AssistantBudget-capped answers
- AuditEvery answer traceable
Commissioned system
The protocol never reaches the product.
Four Rust services behind an isolated protocol layer, so a failure at the boundary stays at the boundary. Answers come from the group’s own history and cite the message they stood on.
Commissioned work, built with and for a partner. Red Sentra keeps an ongoing support role. The partner and the commercial terms stay private.
Commissioned system · Pre-release
A scanner that holds itself back.
Almost every tool in this category is sold on reach. Cortex is designed around three limits that can each stop it on their own — a token budget, a ceiling on work in flight, and a cap per host — so a scan is something a network can absorb.
StatusPre-release. No binary has been published.
We stay after
they ship.
Shipping is the easy half. The ones we have shipped are still running, and they are still ours to keep running.

8 engineers. Remote by default.
Flat, with no sales layer. The person who answers your first message is the person who would build the system.
Founded and led by Viktor Marymorych, Founder & Systems Engineer.
What the team builds
- Backend & distributed systems
- Real-time & streaming
- Infrastructure & edge
- AI systems & agents
- Security engineering
- Mobile & client
Security engineering is one of these, and a historical strength. It is not the category the company sits in.
How we work
- Remote by default.
- Flat, with no sales layer.
- You talk to the engineers building the system.
Tell us what you are building.
Describe the system, the constraint you are up against, and where it currently hurts. Specifics get a better answer than a brief.
