Tacelo designs clear, maintainable web systems directly tailored to real-world needs. Each project is conceived as a reliable tool, fully controlled end-to-end, without fragile dependencies or imposed generic solutions.
No bloated CMS, no third-party plugins to maintain. The code is written to be read, understood and extended — by any developer, at any time.
This website is built on a fully custom backend architecture with folder-based routing, modular template system and PDO data layer. Zero framework dependencies — every line of code is intentional.
The real estate estimator integrates a calculation engine based on 79 multiplicative coefficients, a price-per-sqm database covering 122 municipalities and 333 localities across Valais, and an automatic scoring system to qualify leads.
