Built with care —
shipped with speed
m8te.dev builds the backend other teams rely on — APIs, data models, workflows and integrations — plus the web and mobile clients on top, deployed on AWS or Heroku. Senior engineers only. No ramp-up tax.
Companies we have shipped for
Capabilities
One team across the stack, so the architecture, the interface and the infrastructure are decided together.
Backend systems & APIs
The part that has to be right: domain modelling, permissions, state machines, background jobs, exports and a test suite you can deploy on. Mostly Ruby on Rails with PostgreSQL, because it lets a small team move fast without losing the plot.
Interfaces that hold up
React and TypeScript — fast, accessible screens designed alongside the data model, not after it.
AI bots with purpose
Retrieval, triage, drafting and agentic workflows wired into the systems your team already uses, with evals before launch.
AWS & Heroku delivery
Provisioning, CI/CD, zero-downtime releases, observability and cost that stays predictable as you grow.
Payments & third parties
Stripe, MercadoPago, ledgers, webhooks and partner APIs — built to reconcile, survive retries and never double-charge.
Mobile apps
Apps for your own team or your customers — built on the same API and release pipeline as the web product, shipped to both stores.
Takeover & rescue
Inherit a stalled codebase, get it into staging, pay down what blocks shipping and hand back a team that can move.
How we work
Short cycles, working software in staging from week one, direct access to the engineers writing the code.
Scope in a week
We map the domain, the risks and the smallest version that proves the thing works.
Build in short cycles
Weekly releases to staging with the people writing the code in the room.
Harden before launch
Tests, load, observability, runbooks — so launch day is uneventful.
Run or hand over
We keep it running, or train your team and step back on a fixed date.
