João Roberto is a chemical engineer and FCT‑funded PhD researcher in Coimbra with 10 years of experience bridging applied research, teaching and community leadership to accelerate Portugal’s energy transition. He designs optimisation models and techno‑economic assessments for decentralised e‑fuel production from biogenic CO₂, linking biomass valorisation, carbon capture and hydrogen-to‑fuel synthesis. Equally at home in the lab and in code, he contributes to open‑source projects—improving tests, UI and file‑upload UX in a popular Rails SaaS template and adding coverage for C→Go transpilation—bringing a pragmatic, test‑first approach to research software. His track record includes developing cryogenic CO₂ capture concepts for forest residues, teaching heat‑transfer to undergraduates, and stewarding financial governance as a long‑standing association officer. João pairs rigorous experimental and modelling skills with hands‑on software work and a knack for turning community initiatives into measurable impact.

⚖️ A tool for transpiling C to Go.

Role in this project:

Full-stack Developer

Contributions:10 commits, 5 PRs, 11 comments in 1 month

Contributions summary:João primarily contributed to the `c2go` project, which is a transpiler from C to Go. Their work involved adding and modifying test cases, demonstrating a focus on ensuring the correct translation of C code constructs like `puts`, `switch`, `math.h` and `ctype.h`. These changes involved creating new tests and modifying existing test cases to cover a wide range of C standard library functions. Additionally, they worked on the transpiler itself.
