I am an Experienced Lead Python/Django/FastAPI Web application developer (12+ years exp). I am also a trained in system design, and data analysis. My preference is to work on B2B applications, where there is a greater need to data gathering, manipulation, ELT, and visualization, so a lot closer to a Data Engineer than most Web developers. I've also got a lot of knowledge of data protection policies and how to manage the storing of data in such cases. I am currently working on three different projects. Firstly, a project to analyze Patient data for suitability for observational Medical studies. Secondly a project taking Patient encounters recordings, then converting to text and using NLP and ChatGTP to pull specific information from the encounter to use for billing and formatted notes, that will then be placed back into the EHR. Lastly, I am working on a real estate project to scrape country wide data on property sales, that can then be used for marketing campaigns and other related projects. With these projects I am using Django, FastAPI, Tortoise ORM, ArangoDB, Asyncio, Pika (RabbitMQ), ChatGTP and whisper API's, Spacy, Pandas, Bulma(CSS only framework), and Brython as the main libraries. On the DevOps side, I am using GitLab as a repository, along with its CD/CI capabilities, Ansible for software updates and LXD/LXC containers running on IONOS dedicated servers.

A software specialist with more than 30 years experience developing advanced systems from real-time 3D graphics and animation software, to mobile games and enterprise content management systems. Able to take control of the entire application development process from inception through planning to implementation and delivery. A honed focus on quality and reliability, with a view to ensuring long life and flexibility in all projects undertaken. I practice an engineering/architecture-first approach to software development, focusing on the general software design principles in designing a solution from a conceptual perspective, with no immediate reliance on any particular language or framework. This allows me to rapidly develop high-quality solutions that can be implemented in any suitable language, even languages I've previously not encountered, and ensure the product is of a high standard. Contrary to many software developers, I do not restrict myself by specializing in a particular language or framework, this allows me to think out of the box and be far more reactive to the specific demands of your project.
