AI solutions, built right.

Agents, integrations and custom systems — built by senior engineers who stay on the work from scope to handover.

Senior only
The engineer on the call is the engineer writing the code.
Production first
Logs, retries, evals, cost per call — baked in from week one.
Fully yours
Source, docs, runbook, keys — transferred at handover.
Small, deliberate
Only as much work as we can ship well. No pipeline to feed.
Delivered for
What we do

Three things, done fully. Nothing else.

I
Lead offering

AI solutions

Custom agents, custom integrations, custom systems. Ticket triage, support deflection, eval pipelines, RAG that actually holds up at volume.

  • Agents that run in your stack, not a vendor dashboard
  • Eval + observability from the first commit
  • Model-agnostic — we pick by latency, cost, and fit
II
Custom development

Custom development

Full-stack builds when off-the-shelf doesn't fit. Internal CRMs, operations consoles, data pipelines — shaped around the actual workflow, not the template.

  • Senior engineers on the keyboard, start to finish
  • Shipped in sprints you can audit, not phases
  • Handover includes runbook, on-call doc, team training
III
Engineering talent

Engineering talent

When you need hands on the keyboard for longer — embedded senior engineers placed on engagements between three and twelve months.

  • Vetted by people who have shipped the same work
  • Embedded in your rituals, not parallel to them
  • Scoped out cleanly — no indefinite rolls
Approach

No discovery phase
that never ends.
Four stages. Each one earns the next.

Every engagement runs the same rhythm. It is not a methodology we are selling — it is just the shape of work that consistently makes it to production without surprises. If a phase cannot earn the next one, we stop. You keep what we made so far.

01 · Scope3–5 days

We name the thing precisely

One call, a written scope back. No generic discovery phase. If it should not be built, we will tell you.

02 · Build4–12 weeks

Senior engineers on the keyboard

Sprints you can audit. Weekly demos of what is running in staging — not mockups, not slides.

03 · Harden2–3 weeks

The third-month test

Evals, observability, retry logic, cost controls. We watch it run under real load before we leave.

04 · Hand over1 week

You keep everything

Source, infra, runbook, on-call doc, team training. When we leave, your team owns it fully.

Hirefel OS — internal platform

The platform we run
every engagement on.

Hirefel OS is the internal system we built for ourselves — sprint tracking, eval dashboards, deploy history, runbooks, and the handover packet. Every client gets read access from day one, so nothing we do is ever off-screen.

Live project board — sprint goals, blockers, demo links
Deploy ledger — every change, timestamped, reversible
Eval gallery — pass / fail rates over time, per agent
Handover packet — fully rendered by the final week
The solutions pack

The Hirefel Line. Four solutions, ready to deploy.
