We build software that works.
From idea to product. From product to scale.
An independent studio founded by an engineer who has gone the full distance — from zero to exit. We build our own products and help teams scale what matters.
What we're building
Focused products, shipped and maintained by the studio. Each one earns its place.
Turn any YouTube video into clean, timestamped text you can search, copy and export. Built for students and researchers.
A personal & family finance assistant on WhatsApp and Telegram. Track spending, get answers, stay on budget — powered by AI.
An AI tutor that adapts to how you learn — one real conversation at a time. Currently in definition.
Work with us
Not an agency. Not a freelancer. A founder-engineer who has lived the full cycle — from first commit to exit — and now takes on only a handful of projects at a time, with the judgment of someone who has actually built one.
Consulting
Architecture, technical direction and the hard calls. Senior judgment when the decision actually matters.
Engineering outsourcing
An embedded, senior pair of hands for lean teams. Ship real product, not tickets.
Custom development
From idea to working product — built end-to-end with a modern, pragmatic stack.
Yves Siqueira
Full-stack engineer with 16 years of experience. Co-founder and CTO of Conpass, a product-onboarding SaaS acquired in 2022 after reaching 3M+ users across 1,000+ companies.
Now building YAS Labs — applying everything learned, from zero to exit, to its own products and a few selected projects.
Spec-driven, AI-assisted development. Spec → plan → ship, with Cursor, Claude and the modern toolchain in the loop — speed without losing the senior judgment behind every decision.
