We build infrastructure that doesn't ask for attention.
Coffeen Tech is a small studio with high standards: we design, build, and operate web platforms, APIs, and infrastructure — then we stay around after launch. Judged by uptime, not slides.
What we do
Web & Product Engineering
End-to-end web applications: design, frontend, backend, deployment. We favor boring stacks we can still maintain in five years.
APIs & Integrations
REST services and gateways with real auth, real rate limits, and documentation people actually use.
Infrastructure & Ops
Cloudflare Workers, D1/R2/KV, tunnels, Docker, VPS, monitoring — and we're the ones on call.
Mail Systems
Disposable inboxes, SMTP gateways, forwarding, and spam control across multiple domains — run in production, not in slide decks.
AI Tooling
LLM gateways, retrieval, agent tooling that ships into real products. AI as part of the system, not a demo.
Ongoing Maintenance
Optional retainer: CVE patches, key rotation, offsite backups, and monthly reports a human can read.
How we work
No quote before we understand the problem. One session + a written summary, free of charge.
Scope, estimate, milestones — scope creep is handled at the start, not billed later.
Weekly demos you can touch. No surprises in week six.
Monitoring, backups, security updates — we hand over the keys when you're ready, or keep maintaining.
