Stefan Hanke

With over five years of hands-on professional experience in the independent planning and execution of web-based applications: taking over or further developing a PHP-based production control system, creating an entry control system with entry processing for conferences, smaller 'real-time' info display systems for conferences/festivals, more complex cross-device frontends for websites and backend integration of (then) LBS APIs, transaction-secure payment processing; these were my major engagements before I returned to university for my Master's degree.

Recently, I have been working more theoretically and conceptually at the university in the field of Management Information Systems: wireframes/paper-based prototyping with initial technical implementation ideas were content of my teaching and my ongoing dissertation.

I can therefore discuss conceptual ideas with you as a developer, implement them in the backend/frontend, or simply implement the tickets assigned to me as a programmer.

Gladly pragmatic in a Kanban-oriented reflective working style, if desired.

Classic (incl. "vanilla") PHP (Laravel; previously ZF1,~ZF2, Symfony)

NodeJS (Next.JS; gladly frameworks; Typescript+DTO if needed)

RDBs: MySQL/Maria incl. Stored Procedures/ACID via InnoDB

nRDB: CouchDB (PouchDB)

(Solr - without major algorithm engineering)

Javascript Frontends (ReactJS, Angular, Knockout, previously jQuery; Sockets)

CSS: plain/vanilla, but preferably embedded depending on the framework (Sass...)

DevOps: Debian, Ubuntu; Nginx preferred over Apache; Docker

Unit Testing: preferably frontend-driven (Selenium), backend: framework-dependent

Build server/Linting etc.: important for ensuring stability.

I am not strictly tied to the locations specified here; especially for conceptual topics or older projects/code, on-site meetings can be more productive.
