Search visibility research, question analysis, and source review
I assessed how 42 Portugal appears in Portuguese search and AI answers: which candidate questions surface it, which sources models rely on, and where visibility drops.
Publisher and builder
I built an AI publishing product that combines the topics a reader chooses with the LinkedIn profile details they authorize, so each brief can follow their actual interests.
Fractional CTO and Soul Generator co-founder
I joined EVA Online as fractional CTO and co-founded Eva Soul Generator, helping connect its persistent identity system, authored character world, and $EVA launch on Virtuals Protocol.
Full-stack marketplace engineer
I worked with the OrdinalsBot team on Trio’s full-stack marketplace transaction flow, turning listings and purchases into wallet-signable PSBTs that settle on Bitcoin.
Product engineering
I helped build a fully on-chain Bitcoin game where more than 58,000 pets can be fed, evolve through six stages, or die permanently without an off-chain game server.
Technical lead
I led the custom Bitcoin inscription pipeline for the original 1,500-piece collection, then helped build the recursive traits, animation, customization, and games that followed.
Inscription pipeline engineering
I worked on the Bitcoin inscription pipeline that mapped 76,911 Afghan War Diary records into a verifiable archive that could resume safely across many blocks.
Smart contract and mint engineer
Founder Domingo Mattle called with 24 hours left before mint. I delivered the ERC-721 contract, allowlist, sale controls, airdrops, metadata, and three-way payout path in time for launch.
Lead smart contract and launch engineer
I built and launched the contract, allowlist, sale controls, metadata, and payout path behind a seven-figure, 3,223-token Ethereum sell-out.
Pre-launch smart contract auditor
I audited Planetary Property Association’s smart contracts before launch, reviewing the ERC-1155 Shuttle Pass and ERC-721 Surrealestates mint logic before the system went live.
Founding IT & Pedagogy team member and full-stack developer
After working on the student intranet with the 42 Network development team inside the Paris Bocal, I joined the founding 42 Lisboa team and helped turn Portugal’s first 42 campus into a working school.
Full-stack developer · 42 Network
Inside the 42 Paris Bocal, I worked with the 42 Network development team on the student intranet used to follow curriculum progress and skills.
What teams can expect
That usually means owning the difficult integration, planning for failure, and documenting the decisions another engineer will inherit.
I work on the piece that can sink the product, not only the piece that is easiest to present.
Retries, limits, review paths, and operational controls belong in the design from the beginning.
The next engineer should be able to understand what changed, why it changed, and how to keep it running.
Project questions
Clear answers about my role, public evidence, confidentiality, and earlier-stage work.
A case study explains the original problem, the part I owned, the important technical decisions, the result, and the strongest public evidence I can cite.
No. Most products were team efforts. Each case study separates my role from the wider team’s work and names collaborators or organisations when that context is public.
I can discuss public architecture, decisions, delivery constraints, and results. Client data, credentials, private repositories, and confidential operating details stay private.
Yes. I can begin with an unclear workflow, a difficult technical decision, or a first release. Send the current situation, constraints, and who will own the product.
