skylab is the agency built for the new era. A senior-led two-person team, modern tooling, and a process that ships at the pace of a department — with every line of code reviewed before it reaches you.

Software teams got faster. Most got sloppier. We took the speed and kept the bar.
/01YOU
You bring the problem
A feature, a bug list, an AI automation, a vague idea. We read your codebase and send back a written brief inside 24 hours.

/02WORK
Wide and deep at the same time
Several features advance in parallel, or one hard problem gets sustained focus. Tooling scales the throughput — the judgment stays ours.

You get human-paced delivery
Commits in chunks you can actually review. Daily async updates. One contact, one team.

Nothing reaches you that has not been reviewed by a human.
The AI never talks to the client. That separation of concerns is not a limitation — it is the whole point.
Built a production-scale pipeline for influencer-driven e-commerce with thousands of products that needed intelligent metadata and categorization. Deployed a custom vision LLM pipeline that classifies content at scale, with human review gates on every low-confidence result.

Specialized APIs· Indie → growth
Audio production tooling
Built a suite of music and audio tools: deep integrations with streaming APIs, generative audio testing for creator workflows, and a dedicated sales surface. Three repositories, one team, one vision. Domain-specific engineering in a vertical most agencies cannot touch.

Integrated commerce· Custom
Retail commerce + POS sync
Custom e-commerce storefront for a European retail market with real-time inventory sync from a legacy accounting system. Two-way communication, compliant payments, purpose-built infrastructure. Not a template, not a plugin — the right thing for a specific market.

Agency infrastructure· Product
Internal operations hub
The multi-client operations platform we built for ourselves. Task aggregation, live agenda dashboards, AI briefing, human review, deployment orchestration. We eat our own cooking — every process we learned from clients, we automated for ourselves. This is what you get when you hire us.

Consumer product build
End-to-end consumer product from vision to live application. Frontend, backend, infrastructure, monitoring, the whole chain. Novel UX patterns. Careful performance tuning. Live today, users engaging, the team owns every layer. We focus on products that stay live, not features that get abandoned.

Full-stack. One team. Same standard.
Full-stack web
Next.js, React, Node, Python. Postgres, Supabase, Turso. Real apps with real users in production — e-commerce, SaaS dashboards, content platforms, internal tools. Production standards from day one.
Mobile — iOS + cross-platform
Native Swift for iOS, React Native and Expo for cross-platform. Standalone apps or native layers grafted onto existing web platforms. App Store, Play Store, TestFlight — we handle the whole chain.
DevOps + infrastructure
AWS, Cloudflare, Vercel, NixOS, PM2. CI/CD on every commit, observability that catches problems before users do, zero-downtime deploys and migrations. Deployment is built in from the first commit.
Architecture
Systems sized to the users you have, not a theoretical peak. Multi-tenant by design, event-driven where it matters, AI-native where it genuinely helps users — not for the pitch deck.
AI integration
Claude, OpenAI, Gemini, Perplexity. RAG on private data, autonomous agents, evaluation frameworks that measure output quality. Production LLMs in our stack from the start — we know the seams where they fail and the patterns that work.
Custom solutions
When no existing tool fits, we build the right thing from scratch. Internal dashboards that become an advantage, integrations your competitors do not touch, tools built for one team only — and better for it.
It speaks to the next engineer who reads it, not just the machine. We write for humans first. Clarity over cleverness.
/02
AI is a tool, not a shortcut.
We use AI only where it is reliable; everything else stays deterministic. The model writes code for a structure already decided — it does not decide the structure. A human always reviews. A human always decides.
/03
Process should be invisible.
You should not see the machinery — just one team, one channel, one interface. The complexity stays on our side of the wall.
/04
Scale without compromise.
More code, more features, more load should never mean lower quality. We scale the team, not the standard — senior-engineer judgment on every commit.
/05
Your constraints are features.
A small team, a tight budget, legacy code, weird infrastructure — not obstacles. They shape the solution. The best systems are the constrained ones.
/06
Done means live.
We do not hand off and vanish. We deploy it, monitor it, and respond when it breaks. While we are engaged, the product is not done until it stays live.
FAQ
A freelancer is one person working on a task. We are a senior engineer and a technical project manager backed by a fleet of AI agents, working on an outcome. A senior engineer sits between every output and you. You get the judgment of a CTO with the throughput of a department. Also: no context loss. Our tooling is built for continuity across months, not days.
We start with a short diagnostic sprint — typically one to two weeks. We read your codebase, produce a written architectural assessment, and deliver real working code. If we are a fit, the engagement begins on a monthly retainer. If not, you keep everything we delivered. There is no long-term contract lock-in.
Humans review before anything reaches you. Every PR, every commit, every decision — a senior engineer reads the diff line by line. The AI drafts fast. The human catches the hallucinations, the missing edge cases, the subtle shortcuts. The AI never talks to you. You only ever see the output we approved.
Both. We have done platform migrations, legacy refactors, feature grafts onto existing systems, and greenfield builds. Your codebase conventions become our conventions. By week one, our output looks like it came from your existing team.
Yes. We can be your entire engineering team, or we can augment an existing one. If you have senior engineers already, we pair with them — your team reviews our code, our team reviews theirs. The bar stays high either way.
You can scale down or pause at any time. End of month, you step back. Code is always yours, always committed, always deployable. If we are a fit, great. If you need to pause, that is fine too. No penalties, no lock-in.
Shipping velocity, code review metrics, uptime, and user feedback. The product either works or it does not. You get access to our live agenda dashboard: every PR, every commit, every deployment, visible in real time. You can review on your own calendar.
We fix it. If we shipped it, we own it. Our bar is code that stays live — if it does not, it is not done. Every PR ships with a rollback plan. One message and we roll it back. We design for reversibility from the first commit.
We are based in Lisbon and São Paulo and work with clients across US and EU time zones. Async-first communication means you never wait for our morning. Updates land before your day starts.
You do. All code is yours — always committed to your repositories, on your infrastructure. IP is assigned on contract signature. We sign NDAs as standard, and we agree on data-handling terms — including AI tooling policies — before we touch anything.
