BSysDev9 applications in production right nowAWS us-east-1
We don't build demos. We build the platforms real people open every day to work, get paid and decide — on the docks in hard sunlight, in the clinic, in a yard with no signal. Every project below is live, and every number is one you can check.
Figures measured from the repositories and the live applications — none of them estimated.
Commits come from git rev-list --count; file counts cover each repository's own source, excluding dependencies and build output. When a project grows, this panel grows with it.
Every sector below has our software running inside it. Hover one and see exactly which products serve it.
Hover a sector to see the projects behind it.
Each card opens the project from the inside: the real screens, the architecture holding it up, the stack, and the measured size of the repository.
In productionOperationsLife at the port under control — with every cent accounted for.

Every frame below is the live application, not a mock. It is where the illustration, the video and the data meet, at the moment someone needs them.
Porto na Tela
Overview, by role, by operator and by job type — one dataset cut four ways, with the whole screen tinted by the source the figures came from. Drag to reorder, collapse what you do not use.
Porto na Tela
Today, port history, my history and worker history. Offers, queue and qualification on one screen: 59 vacancies across 8 ships, every category in its own colour, with the berth and gang of each.
Porto na Tela
Wind, gusts, direction, swell, temperature and rainfall hour by hour, at PRO level, on the same screen where the worker checks whether they are qualified.
Porto na Tela
Ship, berth, job type, gang and role for every job in the month, each marked with where the entry came from. The amounts are there and they reconcile with the statement; they are simply not shown here.
Porto na Tela
Gross, net, holiday, 13th salary and severance fund on one side; income tax, social security and levies on the other. Year after year, with the number of jobs worked in each month.
Porto na Tela
Stevedores, handlers and checkers: how many workers, how many engagements, who leads each category. Names protected, numbers on show.
ImpExp
The catalogue matches the cargo-plan text to the model image automatically — Caterpillar, Scania, John Deere, Mercedes, pallet. The inspector recognises the unit before getting near it.
ImpExp
Counts by type and stage: ship, yard and loading, across item, inspection, aboard, stored and finished. Columns are tinted by stage, rows by the vehicle type.
CONFEPAR
Counting by gang, hold and lot happens on the phone, at the quay, with or without signal. One balance per read: the number the foreman sees on the panel is the one the operator sees at the desk — and the hourly pace says when the ship will be done.
CONFEPAR
Every ship that ever gave the category work enters the catalogue on its own, from the rosters: hull record, voyages, how many posts it created and for whom. The ship comes back two years later and the app remembers.
CONFEPAR
The Tally Note is only issued behind Face ID, Touch ID or a PIN, and ConferIA answers by voice, gloves on, what the collective agreement says about the job, the shift and the stoppage — with knowledge generated from the app's own code, never invented.
PRVisor
The engine reproduces the real call-up rules — ordering by job number, ship name, port operator and the priority of registered workers — and shows berth, operator, ship and role. Registration numbers stay protected.
PersonalLife
Each of the 1,322 exercises in the library has its own execution video, plus the two key positions and the muscle groups it recruits. The student opens it mid-set and knows exactly what to do.
PersonalLife
The user picks by sight, adjusts the weight, and the macros compute themselves. 205 foods, each with its own photograph in the same light and framing.
PersonalLife
Search, muscle group and equipment — CrossFit, barbell, dumbbell, machine, cable, kettlebell, band. The professional builds the session without leaving the screen.
PersonalLife
Heart rate, HRV, saturation, steps, active energy, sleep. One layer accepts samples from Health Connect, HealthKit, Garmin, Wear OS and Zepp, and hands back a normalised series.
PersonalLife
Fuel, workshop, parts, services, insurance, fines and taxes — every cost lands in the finances and every due date in the calendar. Car, motorbike and pickup, each with its own odometer and average.
PersonalLife
Partner, children, mother and even the dog: vaccines, allergies, chronic conditions, health plan, and who counts as a dependant at tax time. Birthdays and renewals land in the same calendar.
PersonalLife
Itinerary, places, budget and packing list, with the fare kept under watch. Four trips between planned and done, each counting down to departure.
Destino Estiva
The quiz built like a TV game show: 16 questions a round, 3,083 checked against the exam notice, classic lifelines and its own soundtrack. Played for the house XP, with the ranking on the line.
Destino Estiva
Find the rat the examiner hid in the text of the law. One word swapped per round — a deadline, a subject, a verb — and the student learns to spot the trap before it appears in the real exam.
Destino Estiva
An X-ray of the survey: 20 real exams analysed, ~935 questions in the corpus, 310 dissected, spanning 2019 to 2026. What the board never asks, what always comes up, and where the trap sits.
Destino Estiva
Original content with purpose-made illustration of cargo, equipment and port operations, formulas rendered in KaTeX, and a mini-quiz closing every block.
Destino Estiva
The student revisits what they got wrong, in the format memory responds to best — carrying the same visual identity as the rest of the course.
VidIA Maker
Multi-track, a WebGL2 compositor, the effects inspector and the script side by side. All 45 MCP tools act on this same store, and everything undoes with Ctrl+Z.
ECOlive RG
Real CSS three-dimensional transforms, a catalogue the client administers, and the saving stated without hedging: zero emissions, about R$30 a month, 60 km of range.
This is not a reference diagram: it is the topology serving the products on this page. Hover any service to see which applications run on it.
Hover a service to see what runs on it.
Serverless where traffic is bursty, an always-warm container where latency matters, a dedicated instance where a headless browser lives. The choice follows the workload, never the trend.
Each practice below names the projects where it runs in production and the concrete artefact it produces. None of it is aspirational.
Zod → OpenAPI → OrvalZod route schemas validate, serialise and generate the OpenAPI document. The typed client with React Query hooks comes straight out of it. Change a route, run codegen — the frontend never drifts in silence.
single-table + GSI1/GSI2One primary index and GSIs designed from the queries the screen actually makes. No joins, no N+1, predictable cost and millisecond latency.
Dexie + outbox + Service WorkerSignal drops in the yard. The app keeps the work in IndexedDB, holds an outbox and syncs when it returns. The user never loses what they typed.
tokens + DESIGN.mdTokens, type and palette written as a contract: calm chrome, colour reserved for data. Never a loose hex in a component, never a card nested in a card.
WebAuthn · RBAC · CSPFIDO2 passkeys, multi-tenant RBAC with mandatory company scoping, a locked-down CSP and paid-content protection. Every query is filtered by whoever owns the data.
WCAG 2.1 AA · 44px · reduced-motionWCAG 2.1 AA as a requirement, contrast built for dockside sunlight, 44px touch targets, and an alternative for every animation when the system asks for less motion.
LLM · MCP · RAGA photographed cargo plan becoming a checkable record, local transcription via whisper.cpp, and a video editor an agent can drive. AI where it saves work, not as decoration.
pnpm workspaces + Turborepopnpm workspaces and Turborepo, a domain that knows nothing about frameworks, types shared between API and web. One command builds everything; one package changes without dragging the rest.
Playwright · Vitest · domain testsPlaywright on the user flow, Vitest on business rules, and domain tests that pin ordering, labels and calculations. What would break in production breaks first, in CI.
Every item on this list is running in at least one production project. It is an inventory, not a shop window.

Six fronts that combine into one deliverable: the system your operation opens every day.
The same path that produced the ten products above — with no decorative stage.
We sit with the people who use it and map the process as it is today, side spreadsheet nobody admits to included.
Data model and API contract before the first screen. That is where the documentation and the typed frontend client come from.
Tokens, type and rules written before the components, so the tenth screen comes out like the first.
We deliver end to end, one capability at a time, always with something usable live rather than a prototype standing still.
We test where the system will live: weak signal, hard sunlight, an old phone. What breaks there breaks first, in CI.
Deploy on every push, error monitoring, and evolution with the team already using it. Delivery is not the end — it is where the operation starts.
The questions that come up in every first conversation.
It depends on the size of the operation, not on the number of screens. An institutional site with a CMS is ready in weeks; a platform like ImpExp, covering the ship → yard → loading chain, took months to reach its first production version — and keeps evolving. We deliver in vertical slices, so you get something usable long before the full scope is done.
Data model and API contract first; then one capability at a time, end to end, always with something live. Deploys go out on every push to the main branch, with build, typecheck and tests running first. You follow what is in production, not a status report.
Delivery is where the operation starts. We stay on for fixes, evolution and production error monitoring — the ten projects on this site are all still receiving commits. The shape of that engagement is agreed case by case, matching the rhythm of your operation.
TypeScript end to end: Next.js and React on the frontend, Fastify on the backend, Zod as the single schema that validates and generates the documentation. Data sits in DynamoDB, PostgreSQL or Supabase depending on the case. Infrastructure is AWS — Lambda, App Runner, DynamoDB, S3 — with the interface on Vercel. The full list is in the Stack section.
Every business query is scoped by whoever owns the data, without exception. FIDO2 passkeys where they make sense, a locked-down content security policy, secrets out of the code and paid-content protection. On screens showing personal data we apply blurring and a traceable watermark — including in the captures on this site.
Yes. The first conversation is there to understand the operation and tell you honestly whether it is worth building, buying off the shelf, or leaving alone for now. If we are not the right fit for your case, we will say so on the spot.
