Your software developer in Tübingen

Yes, TFLIT really is based in Tübingen, at Gölzstraße 12. Behind TFLIT is me, Tillmann Lang, a solo software developer: you always talk directly to the person who actually builds your project. That sets the collaboration apart from agencies, where sales and development are often separated by several layers. The proximity has practical benefits: workshops, coordination meetings or a quick look at an interim version can be arranged spontaneously, without long journeys. At the same time I know the Tübingen environment from first-hand experience, from the university and the university hospital to the startups around Cyber Valley, and I know which requirements are typical there. I reply to enquiries within two working days. If you like, we can simply meet for a coffee in the old town and look at your project together.

Yes, university and research projects are one of my core areas. With Esslingen University, for example, I built PraktiMatch, a matching platform for internships. From projects like this I know the specifics of public and academic clients: formal procurement routes, documentation, data protection under the GDPR and accessibility, which the German BFSG has made binding for many digital services. Technically I work with a modern, open stack of Next.js, Payload and Flutter, so results can be operated and handed over without vendor lock-in: often an important criterion for universities. Smaller formats are possible too, such as a prototype for a funding application or a tool for a single research group. In Tübingen the university is practically on my doorstep: if your institute or working group is planning a software project, let's talk about it without obligation.

The cost depends primarily on scope, complexity and interfaces, which is why I do not quote flat prices without knowing your project. Typical cost drivers are the number of user roles, connections to existing systems, individual design requirements and the question of whether a web app is enough or native apps are needed as well. My approach keeps the budget predictable: after the first conversation you receive a written estimate with clearly separated stages. We start with an MVP that covers the most important function, and after each stage you decide whether and how to continue. That way you never spend more than the current benefit justifies, and there are no hidden costs. Just send me a short description of your idea: within two working days you get a first honest assessment, happily also over a coffee in Tübingen.

Both work, and in practice a mix of in-person meetings and remote work has proven most effective. Kickoff, requirements workshops and important milestone reviews ideally happen at your place or with me in Tübingen, because requirements are clarified faster in direct conversation. The actual development then runs remotely, with regular video updates and a test environment where you can try every interim version yourself. I record decisions and open points in writing, so what was agreed always stays traceable. This model combines the commitment of personal meetings with the efficiency of focused development time. Within Tübingen and the surrounding area I can be with you at short notice, and if your team works fully remotely, I simply adapt to your tools and routines.

A first usable result, the MVP, is often ready after a few weeks, depending on scope; more complex projects take correspondingly longer. What matters is less the total duration than the rhythm: I work in clearly separated stages, each of which ends with something working that you can test. A simple website is finished faster than a platform with multiple user roles, interfaces to existing systems or a mobile app for iOS and Android. Your side influences the pace too, for example how quickly feedback and content arrive and how many review rounds are needed. In the first conversation you get a realistic assessment with milestones instead of vague promises. Since I am based in Tübingen, coordination meetings can be scheduled at short notice, which noticeably speeds up projects.
