I'm am currently employed, but can spare some time for side projects. I can take short term projects or work weekly on a long term project for about 12 to 20 hours per week This is what I can offer you: I can work as a Front End, Backend or a Full Stack developer. I can organize new, or evaluate existing projects. I can provide counseling about technologies, development and best practices About my experience: I'm working professionally as a software developer since 2014 I generally work on Web Applications I have a good deal of experience with hybrid applications including: progressive web apps, React Native and Expo I stay up to date and try to learn a new technology every year Product Engineer: As a product engineer I excel in turning requirements into code. I make decision about the necessary frontend and backend work. Database Design. Organize tasks, sprints and milestones. Do code reviews. All in the interest of making a flexible and maintainable app. Full Stack: I'm a full stack developer. I work with backend and front end (including mobile) technologies and languages. Abstraction: Setting up and maintaining core application architecture, state management, modularization and component interaction. Keeping an app easily maintainable requires a solid foundation. Too little abstraction makes the project less flexible, while too much makes it too complicated. I don't just do work - I'm committed to quality and have a professional attitude

I'm mainly a Web Developer, but one with the experience of working with nearly everything inside and outside of his field. All of my external ventures have had the pleasant effect of allowing me to make connections where most people don't even think to look, and make use of all of my skills to the best of my abilities. I absolutely love thinking outside of the box, and most of my personal projects are just a touch crazy in general; I call them creative. I mainly tend to use Python - Flask, Django, and Tornado - for most of my projects, although I also quite enjoy using Golang these days. I've been using Python for about 5 years now and Golang for around 3. I'm also extremely comfortable with Javascript - Vanilla, Vue, React and Angular, and I have quite a bit of fun working on frontends. That said, I'm not going to say that I'm amazing at coming up with Web Designs since it takes me forever to come up with a design I'm satisfied with; I much prefer to be handed a design to work with. I've never failed a project that I've taken on and I've never taken on a project I'm not sure about finishing successfully. I tend to be extremely straight forward about what I can do and how long it might take me to do it. I know my limits, and I try to break past them every single day. So yeah, let's have fun.
