Software architecture, DevOps, and infrastructure consulting for growing businesses.
We design, build, and deploy modern web applications, containerized infrastructure, and IoT data pipelines — from database schema to production.
01 — Services
Modern web applications from database to UI. Production-ready backends, responsive frontends, and the integrations that tie them together.
Containerized deployments, automated CI/CD, and Linux server management. Repeatable infrastructure that ships reliably across environments.
Device data pipelines, building management integrations, and edge infrastructure. Reliable ingest from industrial protocols through to backend services and operator tooling.
Local LLM deployment, vector search, agent frameworks, and speech pipelines. Production-grade AI infrastructure with privacy, persistence, and control.
02 — Case Studies
Architected and deployed a containerized IoT data pipeline processing live industrial device data at a major enterprise facility. Replaced manual deployment with a fully automated Docker Swarm stack, reducing setup time from hours to minutes.
Built a full customer portal from scratch — account management, license generation with Ed25519 cryptographic signing, tiered pricing, download distribution with SHA256 integrity verification, and a private Docker registry with JWT-based authentication.
Architected and delivered internal tools for county-wide capital project management, replacing manual Word/email workflows with a secure database-driven application serving 200+ users across 20 departments.
Built a real-time management console for monitoring IoT device health, alert management, and network topology visualization. Includes license status banners, device management with endpoint cap enforcement, and automated deployment tooling.
03 — Work
IoT Platform Startup
Own deployment infrastructure, frontend modernization, customer portal, licensing, and production reliability for an IoT platform processing live industrial device data across enterprise network infrastructure.
Contra Costa County Public Works
Architected and delivered internal tools for county-wide capital project management, replacing manual Word/email workflows with a secure database-driven application serving 200+ users across 20 departments.
Martinsen Technologies
Operated an independent contracting business serving residential and commercial clients across the San Francisco Bay Area.
04 — Projects
Self-directed build-out of a local LLM stack — inference, embeddings, reranking, STT/TTS, and agent frameworks — alongside persistent memory experiments using PostgreSQL, vector search, and graph-based retrieval.
Self-hosted infrastructure running multiple services across Docker, with Linux networking, Cloudflare Tunnel, Tailscale VPN, and continuous integration for open-source tooling.
05 — About
Martinsen Technologies is led by Nicholai Martinsen — a full-stack engineer with production experience designing, building, and deploying modern web applications, internal tools, and containerized infrastructure from the ground up. Skilled across backend systems, database architecture, React/TypeScript frontends, Dockerized deployments, and CI/CD.
Before software, Nicholai spent five years as his own general contractor — running a solo business across the San Francisco Bay Area handling home renovations, remodels, custom metal fabrication, welding, and handyman work. Projects ranged from one-hour emergency repairs to month-long full renovations.
That contractor background is what shapes the company: figure out what's actually needed, build it right, and ship it. The same pragmatism that delivered a custom gate on-site shows up in how backend systems and deployment pipelines get designed.
Based in Reno/Tahoe, NV, with regular availability in the SF Bay Area. Available for remote contract work worldwide.
