# Benjamin Tietz — Founder of BTECH SOLUTIONS ## About Benjamin Tietz is the founder of BTECH SOLUTIONS, based in Hückeswagen, NRW, Germany. In his own words: "I build and operate software that stays in production — from the Angular frontend through the Django API to the server it runs on." ## Contact - Email: mail@benjamin-tietz.com - LinkedIn: https://linkedin.com/in/benjamin-tietz - GitHub: https://github.com/BenjaminTietz - Website: https://benjamin-tietz.com ## Skills - Frontend: Angular, TypeScript, SCSS, RxJS, Signals - Backend: Django, Django REST Framework, Python, PostgreSQL - DevSecOps: Docker, Docker Compose, CI/CD, Nginx, Linux, OWASP ## How projects are labelled Every project carries exactly one classification: - Own product — built and operated by Benjamin Tietz, at his own risk. - Concept study — built to demonstrate something. NOT a real offer, no real customer behind it. - Training / early practice — learning projects, dated by year. - Client project — paid or contractually agreed, named only with the client's approval. None is listed publicly at the moment. Team projects are named as team projects, but collaborators are NOT named: publishing a person's name requires their consent, and none is on file. "Team project" carries the statement; a name list would add nothing to it. All demo URLs below were checked with curl.exe on 2026-08-10, ThaiKickStarter on 2026-08-11 (HTTP 200, with a negative probe per domain). Contribution and origin: in the training projects the visual design was supplied by the Developer Akademie, which holds the rights to it; it is shown here as a reference only. For Coderr the entire frontend was supplied as well — the task there was the backend. Where the design or the frontend was not his own work, the entry says so. ## Projects — in operation - Thailand Vloggers — own product, live since 2026. A live Thailand platform with a high-performance Angular frontend, creator discovery, local favourites and public community areas; cron jobs and a Django backend keep the data current. Further community features are expanded step by step.

Bilingual Angular SSG showcase with simulated booking and voucher flows. https://hoehenwerk.btech-solutions.eu/ - Luxus Loft Köln — CONCEPT STUDY, not a real offer. The apartment is fictional: the demo's own imprint states that it is not a real accommodation offer, and btech-solutions.eu lists the same reference as a "Konzeptbeispiel" (concept example). Angular, TypeScript, SSR/SSG, SCSS. https://luxusloftkoeln.btech-solutions.eu/ - Lease Loop — CONCEPT STUDY, not a real offer. A guesthouse and rental system in three parts: an SSG booking site, a client-side PMS application for the operator, and a Django backend. Built as a team project, not solo work. Angular, TypeScript, SSG, Python, Django, REST APIs, Docker. https://lease-loop.com/ — repository: https://github.com/BenjaminTietz/LeaseLoop_Frontend ## Projects — where I learned it (chronological) - El Pollo Loco (2023) — solo, practice project predating the curriculum. 2D jump-and-run game.
