What we build

Four things we do end-to-end.

We take responsibility for the whole thing: architecture, code, deployment, and the day after launch.

01

AI Agents & Automation

Workflow automation, LLM agents, and business logic wired directly into your real systems: CRMs, databases, messaging, spreadsheets.

02

Custom SaaS & Product Engineering

Multi-tenant SaaS, internal tools, dashboards and admin panels. Designed properly the first time and built to be maintained.

03

Voice & Messaging AI

WhatsApp, voice bots and conversational systems for support, lead handling and operational workflows. Connected to your CRM and stack.

04

Integrations & Infrastructure

REST and GraphQL APIs, third-party integrations, cloud infrastructure and production DevOps. The plumbing that keeps everything reliable.

Why HINTX

You work directly with the engineers writing your code.

No account managers between you and the build. That is how projects stay on scope and problems get solved fast.

  • Senior engineers only

    Everyone on your project has 8+ years shipping production software.

  • Built to be maintained

    Clean code, real documentation, and standard tooling so anyone can pick it up later.

  • AI-native workflow

    We use LLM tooling to move faster without cutting corners on review or testing.

  • Integration-first thinking

    Most work involves systems that already exist. We plan around your stack, not against it.

  • You own everything

    Repository, deploy pipeline, credentials, documentation. Nothing locked to us.

  • Support after launch

    A retained arrangement with a defined response time, or a clean handover to your team.

Process

From first call to production.

  1. 01
    Discovery

    We map goals, constraints and existing systems. No jargon.

  2. 02
    Architecture

    System design, tech choices, cost and delivery plan agreed before we build.

  3. 03
    Build

    Weekly demos, clear progress, code you own from day one.

  4. 04
    QA & Launch

    Automated tests, staging validation, production rollout with a rollback plan.

  5. 05
    Support

    Monitoring, iterations, and support if you want it.

Tech we build with

A pragmatic, boring-when-it-needs-to-be stack.

FAQ

Common questions.

Don't see yours? Ask directly.

What kind of projects do you take on?

AI automation, custom SaaS platforms, internal tools, integrations, voice and messaging AI, and full-stack product engineering.

Can you improve an existing system instead of rebuilding it?

Yes. A lot of our work is targeted improvements: new integrations, automation layers, performance work, or extending something that already mostly works.

Do you build AI agents and automations?

Yes. We build LLM agents, n8n workflows, and custom orchestration wired to your real systems.

Can you handle both frontend and backend?

Yes. Architecture, backend, APIs, frontend, mobile where needed, and DevOps.

How does a project start?

A short discovery call, then a written scope with milestones, cost and timeline.

Do you support projects after launch?

Yes. Either a retained support arrangement with a defined response time, or a clean handover to your team with documentation.
