Senior engineering for scale-ups that cannot afford architecture mistakes

Dedicated senior squad for scale-ups. Real technical seniority, without the overhead of hiring.

Do any of these sound familiar?

If so, you're in the right place.

Stalled roadmap. Overloaded team.

Every sprint, new features compete with MVP-era tech debt. Nobody wins.

Agency code nobody on your team can maintain.

Shipped on time — but turned into technical debt your team will carry for years.

4–6 months to hire in-house. The roadmap won't wait.

Interviews, onboarding, culture — while the product needs to be in production next week.

Seniority for architecture, not more junior execution.

The difference between someone who writes code and someone who decides architecture you'll live with for years.

Tried a freelancer. Became a microcontract manager.

Instead of moving faster, you coordinated — and ended up with no docs, no process, no continuity.

Technical capabilities

What we know how to do — and how it fits your product.

Product Engineering

React · Next.js · Node.js · TypeScript

The core of the product. Interfaces that convert, APIs that scale, code the next engineer can understand and evolve without scheduling a meeting.

AI Engineering

LLMs · RAG · Agents · OpenAI · Anthropic · Vector Stores

Real AI integration in product — not a ChatGPT script pasted on an interface. We architect pipelines with cost control, observability, and fallbacks designed for production.

Mobile

React Native · iOS · Android

Native-grade app experience. One codebase, real performance on both systems, architecture built for the product's long-term roadmap.

Backend, Data & Cloud

Node.js · Python · PostgreSQL · AWS · GCP · CI/CD

Infrastructure that supports real growth. Well-designed APIs, reliable pipelines, automated deployments, and alerts that arrive before your customer complains.

How we work

Process, not promises. Every phase has a concrete deliverable and a timeline.

011 week

Technical assessment

Architecture audit, risk mapping, justified technical proposal. Before any line of code.

Deliverable:

Written assessment + proposed architecture + estimates

021–2 weeks

Solution design

ADRs, system diagrams, scope contract. You approve everything before execution starts.

Deliverable:

ADRs + architecture diagram + signed scope

03Agreed duration

Squad execution

Sprints, senior code review, observability from day 1. Weekly report and real-time repo access.

Deliverable:

Reviewed PRs + production releases + weekly report

04No lock-in

Handoff or continuity

The code is yours, the docs are yours. If you want to internalize, you'll manage.

Deliverable:

Technical docs + knowledge transfer + transition support

The engineering behind Devtrue

Who you're actually hiring.

Devtrue was built from 15 years of building real systems — from products in Fintech, FoodTech, HealthTech, and Logistics to high-responsibility infrastructure.

We've led technical teams, held the CTO seat, and failed in production. We learned the difference between writing software and building product. When you hire Devtrue, you hire accumulated technical judgment.

Good code is code that someone who hasn't been hired yet can understand. Good architecture is what doesn't go viral on Slack at 3am. And a good engineering partner is the one who tells you what you don't want to hear before you spend the budget.

Engagement models

Choose the model that fits your product's current moment.

Project-based

Defined scope, agreed timeline, clear deliverable.

The project ends when the code is in production — documented, tested, and ready for your team to evolve.


Ideal for:

Critical feature, MVP, module rewrite, integration.

Investment:

USD 10,000 – 50,000 / R$ 30,000 – 150,000

Dedicated Squad

Dedicated senior team, monthly retainer.

Senior technical capacity available without the overhead of hiring, onboarding, and culture management.


Ideal for:

Scale-ups in continuous growth that need cadence and predictability.

Investment:

Monthly retainer — defined at assessment

Technical Advisory

Technical decisions, ADRs, senior code review.

Lower entry ticket. We open the technical relationship; you decide the next step with clarity.


Ideal for:

Those who need seniority to decide — without full-time execution right now.

Investment:

Lower monthly investment — defined at assessment

Qual as vantagens e desvantagens de utilizar o Firebase para desenvolver um MPV?

Qual as vantagens e desvantagens de utilizar o Firebase para desenvolver um MPV?

Neste post, vamos explorar as vantagens e desvantagens de utilizar o Firebase como plataforma de desenvolvimento para um MVP (Minimum Viable Product). O Firebase é uma plataforma de desenvolvimento móvel e web que oferece serviços para desenvolvedores, como armazenamento em nuvem, autenticação, banco de dados em tempo real e muito mais. Discutiremos como a facilidade de uso, velocidade de desenvolvimento, escalabilidade e custos acessíveis são vantagens do Firebase, mas também abordaremos limitações no controle de infraestrutura, restrições de personalização e possíveis custos adicionais. Ao final deste post, você terá uma compreensão melhor de como o Firebase pode ser usado no desenvolvimento de um MVP e saberá se é a melhor escolha para o seu projeto.

Questions CTOs ask before hiring

Senior code review on 100% of pull requests — no line goes to main without review. We apply static analysis, automated testing, and security checklists from day one, not as a final step.
The code is yours from the first commit. We work in your repository, with inline documentation and ADRs that explain the reasoning behind each architectural decision. At the end, we run structured knowledge transfer sessions so your team can evolve without us.
Yes. During the assessment phase, you meet who will work on the project and evaluate technical reasoning in practice. We don't send CVs for approval — we have a real technical conversation where you decide if it makes sense.
No abusive lock-in. Fixed-scope projects have contractual timelines. Squad models require 30 days notice. You'll never be held hostage by a contract to access your own code.
Yes, on all projects. Before any technical conversation about your architecture, product, or sensitive data.
AI doesn't write autonomous production code in our process. We use it as a support tool — boilerplate generation, code analysis, documentation. Critical code always goes through senior human review. Technical responsibility is ours, not the model's.
Yes. Contracts in English, payment via international wire transfer, Wise, or Stripe. We've structured our model for US and Latam clients. The assessment conversation can also be conducted in English.

Ready for a real technical conversation?

Book a 30-minute assessment. No sales pitch, no generic proposal.

What you get — whether you hire us or not:

  • An external perspective on your product's current technical state
  • 2–3 practical recommendations for your specific situation
  • Clarity on whether working together makes sense

Free conversation. 30 minutes. No obligation.
