We engineer digital systems through an asymmetric competitive advantage: bridging 25 years of design systems craft and typography with zero-latency edge compute (Cloudflare Workers) and deterministic AI rails. Complete, high-performance architectures from process blueprint to the production interface.
Led by Mariusz Ruski, the MENTENSOR engineering practice unites 25 years of design systems expertise, edge infrastructure, and deterministic AI workflows. We operate as a dedicated engineering unit connecting every layer around a singular business objective.
We translate complex processes into intuitive, high-density working interfaces. User journeys, design systems, and accessible components are engineered alongside application logic and data pipelines. Your team receives a cohesive product built to adapt to evolving requirements.
“Start by understanding the problem.”
We design and connect applications, APIs, object storage, and distribution channels. Edge caching and serverless execution minimize redundant compute and offload core infrastructure. Every architectural decision rigorously balances permissions, latency, and operational expense.
“Measure before you scale.”
We integrate deterministic AI guardrails into classification, document processing, and data extraction. We define strict validation rules, eliminate hallucinations, and engineer precise Human-in-the-Loop checkpoints. Value is measured by hours saved and predictable token unit economics.
“Use only the complexity the task needs.”
We evaluate every AI model, agent workflow, and edge service against concrete operational criteria: answer precision, latency, data governance, and token unit economics. We prototype and stress-test assumptions before any production rollout. The architecture strictly defines the boundaries of AI autonomy, human audit checkpoints, and failover fallbacks.
Explore the problem, scope of work and architecture behind each project. Completed work, pilot programmes and systems under development are identified separately.
A growing publication needed to handle more traffic and distribute content without replacing its editorial CMS. The work connected Cloudflare caching, article delivery to Onet.pl, translation, audio and subscriber notifications into one publishing workflow.
A pilot connecting the patient form, inquiry classification and SMS notifications for clinic staff. The architectural focus is the whole contact workflow: input validation, routing and a clear handoff to a person. Medical decisions remain with the clinical team.
Heavy scripts and media competed with the interface during page load. Changes to script execution, video delivery and fonts reduced Total Blocking Time from 750 to 10 ms in the reported lab comparison. Separate work for The Bay Club moved PDF delivery to Cloudflare.
A platform for infrastructure agreements needed document handling, access control and support for extracting contract obligations. An initial MVP validated the workflow; the next development phase uses a dedicated application, relational data and a separate AI analysis service.
For founders, product teams and engineering agencies that need senior architectural direction alongside implementation. A recurring engagement to develop the system as business priorities change.
For a specific decision or bottleneck: validate an AI workflow, build a critical integration or improve system performance. The scope and delivery target are agreed before the sprint starts.
Thank you. Mariusz Ruski will review your project context and reply with a proposed next step within one business day.
Define who uses the system, what should improve and how success will be measured. Identify constraints and risks before choosing the architecture.
Work directly with Mariusz Ruski on architecture and implementation. Review working increments against agreed criteria and keep important decisions documented.
Receive code, documentation and operating guidance. Scope, ownership and third-party dependencies are defined in the agreement so the system can be maintained and developed further.
