    I have worked as a Freelance python developer for 10+ years, plus as a Database manager and application developer prior to that. I have worked mostly in Web based applications, using Django, FastAPI, Springbook, DRF etc, but have worked a lot with Data driven applications using realtime messaging with RabbitMQ, AysncIO coding, distributed applications and of course with deployment of applications across multiple instances/containers. I am trained and experienced in system design as well, using UML and documentation to go through both system and business requirements. I have unique still when it comes to understanding the business needs for a project, along side the system needs. This includes having good communication skills when it comes to dealing with customers and clients. Don't be afraid to place me in a meeting with potential customers. I can provide valuable insights. On the documentation side, I have a nice collection of articles on medium.com, dealing with some technical and non technical issues. My articles on using Pydantic and HTMX seem particularly popular. I am, at heart a backend and data specialist. I don't specialize in javascript frameworks and have no plans to do so. I am an expert with data,being able to see how to use, store, transform and manipulate it. When it comes to AI, I am experienced in many aspects of Machine Learning, but this is a very large area of study. One concept that I like to stick with is watching the error rates of such systems. I have worked in many large corporations, and I know that error rates are critical. LLM's such as Chat-GTP have errors rates of 10% or more. This is not acceptable. While they are amazing, as a Business analyst I know they cannot be used at the core of a business as they stand for critical data. That said other ML and NN models can and should be used. For AI and programming, I use LLM's in a limited fashion. when it comes to bleeding and cutting edge tech, they are next to useless. My Article of Pydantic can be used as an example as Chat-GTP and Gemini, both give useless advice when it comes to coding the dataclasses. For DevOps, I have worked with AWS and Azure, but found that both work out rather expensive in the long run. I personally use and rented Dedicated server and use LXC containers to run multiple instances. For deployments, I an well versed in using Ansible and developing Functional testing via the Robot Framework. When it comes to most webapps, True Unit tests are not that useful, while functional tests are much better. I also use GitLab as my primary repository system and I will create and share a repository with a client at the start of a project. That said, I have github and bitbucket accounts. I've also used their AWS git repository, but the security and features of that system are annoying and limited. When it comes to project management, I am well versed in agile project management, but since I usually work alone, its not something that comes into everyday use. I am well versed in project management applications, kanban boards, and group chats like Slack. I do use Linux however and Microsoft teams does not play well with my system. This also bring in that fact that I work almost 100% with Linux/Ubuntu machines. I can use Windows, and have no issue running such in VirtualBox, but I do not have a high level of experience when it comes with Windows DevOps. Instead I use Nginx, Gunicorn, Uvicorn, SystemD, LXC etc. With Documentation, I do enjoy writing articles and system documentation using MkDocs etc. I do stick to using Markdown though. Word processors are somewhat limited and PDF's are just annoying. When it comes to dealing with clients, I have a simple policy, if you pay me for work, the work is yours. I always keep the work in Repositories and give you access. I will not claim or withhold work unless no payments have been made. I am also happy to work on consultations and give advice on the best technical stack. I am NeuroDivergent and I can often see potential roadblocks long before others

    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.
