All Projects

Sole developer, and the subject of my thesis

A full-stack incubator management system built for the Eduardo Mondlane University business incubator, and the subject of my undergraduate thesis. It follows a startup through the entire journey, from application and pre-incubation to incubation and demo day, with startup and mentor registration, configurable performance tracking, statistical reporting and an event calendar.

• Models the incubation lifecycle as explicit phases, so a startup cannot silently skip a stage.
• Configurable performance metrics and milestones, because every incubator measures success differently.
• Role-based access separating incubator managers from the incubated startups themselves.
• An application flow that turns prospective startups into records without manual data entry.

Founding member and technical lead at Kudondza Solutions

A tutoring platform built for Kudondza Solutions, the education technology startup I co-founded, incubated at the Eduardo Mondlane University. Students find and book tutors, subject communities give them somewhere to ask questions, and mobile money handles the payments.

• Mobile money payments through the M-Pesa SDK, which is how money actually moves in Mozambique.
• Push notifications with Firebase Cloud Messaging, so a session request does not depend on someone refreshing a page.
• Real-time chat scoped to active tutor and student pairs, rather than an open messaging free-for-all.
• Subject communities with posts, comments and likes, to capture the questions that do not justify booking a session.

Founding member: built and deployed it

The public site and blog of Kudondza Solutions, the education technology startup I co-founded and which was incubated at the Eduardo Mondlane University. Separate from Explicaki, which was the product: this is the front door for the company itself.

• Astro with MDX, so the blog is writable by someone who is not a developer.
• Static and cheap to run on purpose, which matters when a startup has no revenue yet.
• A useful reminder that a company needs a credible public presence well before its product is finished.

Pro bono: build, deployment, domain and email

The website of ASSOJ (Associação para o Empoderamento Juvenil), a Mozambican non-profit founded in 2020 that trains young people in entrepreneurship and innovation, and incubates the businesses that come out of it. I built and deployed it for free, and the brief I set myself was that it should cost the organisation nothing to keep running.

• Deliberately pro bono. This is the same ecosystem I work in professionally (innovation, incubation, youth skills), so contributing to an organisation doing it from the non-profit side is not charity, it is participation.
• Designed for zero running cost: a static Astro build on a free host, so the only recurring expense is the domain. Money an NGO spends on hosting is money not spent on its programmes.
• Handled the whole delivery, not just the code: domain registration, DNS, and email on the domain configured into the managers' own inboxes so they could actually send and receive.
• Replaced an earlier hand-written holding page with a real site the organisation can grow into.

Full-stack developer

A digital talent marketplace connecting Mozambican students and graduates with employment, entrepreneurial and academic opportunities, built around multiple profile types (talent, companies, institutions, investors) and skills-based matching.

• Four distinct account types sharing one opportunity model.
• Anonymous browsing plus a blacklist, so a candidate can look around without their current employer noticing.
• Skills-based matching with opportunity notifications, instead of a search box and hope.

Sole developer, freelance

A lightweight sales record system for tracking daily meat sales, with automatic weight and value calculations, per-operator tracking, statistics and CSV export. A small project, and the one where I learned that the reporting screen is the feature the client actually cares about.

• Automatic calculation from product and value, because manual arithmetic at a counter produces errors.
• Per-operator sales tracking, which was the real requirement behind a vaguely worded request for statistics.
• CSV export as a backup strategy, since the client trusted a spreadsheet more than my database.

Fork maintainer and operator

A self-hosted fork of big-AGI running on Vercel under my own subdomain, wired to several model providers. It replaced a browser extension I used for querying multiple models side by side, and it is where a lot of my day-to-day model comparison happens.

• Deployed on Vercel with provider keys kept server-side, so the browser never holds a credential.
• Multi-provider setup through OpenRouter, which makes comparing models a configuration change rather than a new subscription.
• The beam feature (querying several models at once and merging the answers) is what made me drop the extension I was using before.

Everything, including the parts I keep meaning to fix

My personal blog and portfolio, built on Astro with the Fuwari theme and deployed to Cloudflare. It is where I write about the engineering decisions I cannot show as code, which turns out to be most of them.

• Astro content collections with Zod-validated frontmatter for posts, and a separate data module driving these project cards.
• A markdown pipeline extended with admonitions, GitHub repo cards, KaTeX math, reading time and excerpts.
• Full-text search at build time with Pagefind, so search costs nothing at runtime.
• Page transitions with Swup, which means every client script has to tolerate being re-run on navigation.

For an audience of one

A personal collection of AutoHotkey v2 scripts for window management, text expansion and the small repetitive actions that add up over a working day. Not impressive, and easily the highest ratio of time saved to lines written of anything I have built.

• AutoHotkey v2, which is a different language from v1 and worth the migration.
• The scripts that survived are the ones fixing things I do dozens of times a day, not the clever ones.

Student developer

A platform connecting homeowners with domestic service professionals, built as a university project. It works, and it is also a museum of things I now know not to do. I keep it here because pretending I started out competent would be a strange thing to claim.

• Passwords hashed with MD5, which was wrong even in 2020, and is the single clearest marker of how much I did not know.
• Almost no component separation: most of the logic lived in a handful of enormous files.
• It did ship, and it did work, which at the time was the only thing I was measuring.

A series of projects completed during my Udacity Full Stack Web Developer nanodegree, including: Fyyur (an artist booking site), Trivia API, Coffee Shop Full Stack, and a containerized Flask app deployed to AWS EKS. This is still my only structured exposure to Docker, Kubernetes and formal testing.

• Fyyur: SQL and data modeling for the web, with Flask and PostgreSQL.
• Trivia API: API development, documentation and unit testing.
• Coffee Shop Full Stack: identity and access management with Auth0.
• Deploying a Flask app to Kubernetes on AWS EKS: containerization and server deployment.

An artist booking platform that connects performers with venues through a scheduling system. Built for the data modeling module of the Udacity nanodegree.

A backend API powering a trivia game, with a RESTful design, thorough documentation and error handling. Built for the API development module of the Udacity nanodegree.
