What we do
Next to each service, the projects where we have already done it.
Custom web systems
SaaS
Platforms that serve many customers on one codebase, with plans, subscriptions and an admin panel.
Mobile apps
Windows software
Programs for Windows 10 and 11, from an app that tunes the system for gaming to a file manager you run with a controller.
APIs and payments
Checkout, Pix, subscriptions and webhooks that grant access as soon as the payment is approved.
High-traffic portals
Official portals for mass events. We build the platform, and the client’s team publishes schedules, traffic updates and news.
Maintenance and upgrades
We keep shipping versions after launch. ControlFS has a public changelog of more than 80 KB.
Before launch, we try to break in.
We run our own pentest server. All the software we deliver goes through security testing on it before release.
How we handle securitySafeguards already in the projects’ code
Row Level Security in the database
Supabase enforces Row Level Security, with owner, admin, member and reader roles in each workspace.
AES-256-GCM link and signed updates
A QR code turns the phone into a controller, over a link encrypted with AES-256-GCM and paired by code. Each automatic update is checked against a signed manifest and SHA-256.
Idempotent webhooks
Webhooks have automatic retry and idempotency: if the same event arrives twice, it is processed only once.
Data anonymized before AI
Análise IA receives the clinic’s data already anonymized, in line with LGPD (Brazil’s data protection law), and the audit log shows records by entity and by user.
How we work
Assessment
We talk to the people who run the process today and map where the operation gets stuck.
You getFirst-version scope, risks and a proposal.
Architecture
We define data, integrations, stack and hosting based on what the project has to support.
You getTechnical design and a delivery plan.
Build in short cycles
Each cycle ends with a delivery you can open and test, with no waiting for the end of the project.
You getA working version every cycle.
Testing and pentest
We test the main flows and run the software through our pentest server before release.
You getFixes made before launch.
Release and upgrades
We publish, follow how it gets used and keep improving what we delivered.
You getSoftware live, with the next versions planned.
