- AI and Machine Learning — Agentic AI, computer vision, NLP, vector databases, and custom ML models
- Fractional CTO — Senior technical leadership at 30-40% the cost of a full-time hire
- Digital Health — DICOM, HL7, FHIR, telemedicine, medical imaging, and EHR integration
- Product Development — Strategy, architecture, and shipping with Shape Up and OKR methodologies
- Infrastructure — PostgreSQL, Docker, AWS, Azure, bare metal servers, and monitoring
Why Teams Choose Us
According to Gartner, by 2028, 33% of enterprise software will include agentic AI. We help teams adopt this technology with production-ready systems, not proof-of-concept demos. Our founder has co-founded two digital health companies and shipped telemedicine systems connecting healthcare facilities across 5 continents, including a project linking Antarctica with the International Space Station.
We choose technology pragmatically based on the problem. Our primary stack includes Python, Elixir, and Ruby, supported by PostgreSQL, Docker, and modern AI frameworks. We follow a weekly shipping cadence — something goes live every Friday. This approach combines the discipline of Shape Up with the focus of YAGNI: build only what is needed, ship it, and iterate.
Frequently Asked Questions
What is a fractional CTO?
A fractional CTO provides senior technical leadership on a part-time basis, typically 2-3 days per week. This gives startups and SMEs access to 20+ years of CTO-level experience at 30-40% the cost of a full-time executive hire. We set technical direction, mentor engineering teams, make architecture decisions, and manage technical debt.
What AI services do you offer?
We build production AI systems including agentic workflows with LangChain and LangGraph, computer vision pipelines with MediaPipe and PyTorch, NLP and embedding systems with vector databases, and custom ML models. We focus on practical AI that solves real business problems in digital health, lab automation, and enterprise operations.
Do you work with healthcare projects?
Yes, digital health is a core specialization. Our founder has co-founded two digital health companies and has deep experience with DICOM medical imaging, HL7 and FHIR interoperability, telemedicine platforms, EHR integration, and clinical workflow automation.
