Twofold is a two-person studio in Sofia. We replace PDF price lists, spreadsheet catalogues and 2012 websites with software people can use.
Buyers pick a building from its facade, a floor from the plan or a 3D model, and an apartment with its price and room areas.

A 2012 website and a spreadsheet download became a searchable catalogue of 3,646 remedies, with a price for every form.

A merchant checkout that walks through EMV 3-D Secure 2: frictionless approval for low-risk carts, an OTP challenge for risky ones.
HTML · CSS · JavaScript
Smaller builds, coursework and experiments. Not client work, but the same habits: sign-in done properly, data that stays consistent, and code you can read.
Plamen

Core developer at CarrierX, where he moved a decade-old customer portal from Ember to React and is rewriting the Rails backend in TypeScript. Writes Rust on the desktop and runs his own servers, including Gitadel, the Git forge this studio's code lives on.
Fullstack · security
Builds Next.js applications on Prisma and PostgreSQL, and wrote his thesis on secure sign-in: email confirmation, account lockout, two-factor and magic links. His earlier work in Java and C covers sockets, threads and inter-process messaging.
The two of us. There is no account manager in between: the people on the call are the people writing the code, and you can see both of us on this page.
Yes, that is usually the point. Helios's staff keep 3,600 products, prices and opening hours current in Sanity Studio; Arkada's apartments, prices and availability live in Payload CMS. You get an editor, not a ticket queue.
Yes. Helios is in Bulgarian, Arkada in Bulgarian and English, and Bukinistika in Bulgarian, English and Russian. Translations live next to each other in the CMS, so a new language is content work rather than a rebuild.
Good. We import it. Helios's old WordPress pages and its remedy spreadsheets went straight into the new CMS, and Bukinistika's catalogue is kept in sync by a scraper.
We can host the site on our own servers and keep it updated, or hand it over to you with the code and the deploy setup. Either way you own the code.
Email us what you have today: the website, the spreadsheet, the PDF, whatever customers see now. We will reply with what we would build first and roughly what it takes.
