A one-person venture studio from Johannesburg — building privacy-first software and bold creative brands that respect the people who use them.
Chevza builds things that move the world one product, one frame, one file at a time.
Everything the studio is building, in one place — shipped products, brands in build, and one very large idea. Each card opens the full story.
AI-native file organisation for the command line. Your AI can suggest — FileMayor can act. Local-first, privacy-first, six-layer security (The Chevza Doctrine).
A Johannesburg photography studio — portraits, brand & commercial, weddings, and fine-art prints. Home of the bold black-and-white Iconoclast portrait series.
The sound side of the studio. Debut single “Mingo” — out now on every major platform. Press play without leaving the page.
A self-powered subterranean megacity — SMR thermal core, autonomous maglev, tokenised commercial tunnels, agritech & IP exports. A $100B concept taken from whitepaper → 3D model → film.
Enter the city ↗South Africa's one-stop events platform — discover, book, and run events in one place. Web + mobile, built on FastAPI & Supabase.
See the poster ↗A whole-farm operations platform for African farmers — husbandry and cultivation in one system: herds, fields, feed, yields, and the money behind them.
Follow the build ↗A tufting studio, and more — building quietly under the Chevza umbrella.

The city we build downward.
A self-powered subterranean megacity — one reactor heart, autonomous maglev arteries, tokenised tunnels, and a sci-fi feature built from the same blueprint. Explore the interactive 3D cross-section, read the whitepaper, watch the story take shape.
I'm Lehlohonolo Goodwill Nchefu, an independent founder working as Chevza. From Johannesburg, I design and engineer things with global ambition, local-first foundations, and a refusal to trade trust for convenience.
FileMayor began with a sharper question: what if AI could do more than describe the work? Two years later, the answer is a CLI, desktop, and PWA ecosystem — secured by its own six-layer doctrine and installed more than 25,000 times. The same hands shoot the Iconoclast portrait series, released "Mingo", and are quietly building the rest of the roster.
The work sits where systems thinking, product instinct, and visual culture meet. Fewer compromises. Better software. A point of view you can feel before you read the changelog.
Notes from building all of this solo — what worked, what didn't, with receipts.
Open to interesting projects, partnerships, and collaborations. Based in Johannesburg — works everywhere.
