Ask HN: Freelancer? Seeking freelancer? (July 2025)
Please only post if you are personally looking to hire a freelancer or work as one. Agencies, recruiters, job boards, and so on, are off topic here.
Looking for computer vision work. Multi-view stereo, camera calibration, SfM, scene reconstruction, 3D object triangulation, 3D multi-object tracking. Object detection, tracking, video processing. I mostly work in Python and C++, but the stack is not super important to me. I have 14 years of experience as a software engineer. Self-directed, and I do not require a lot of management. I go the extra mile producing technical notes, reports, visualizations, etc. to help communicate my results. References available upon request. Willing to travel.

I have almost 10 years experience with Python/Django and worked with many tools/technologies/libraries related to it (Vue, pytest, various CI/CD tools, docker, htmx, alpine, websockets etc). I especially love to dive into odd bugs and optimize slow queries/functions. I am a big fan of testing and documenting.
I maintain a few applications for clients (as the sole developer), but can also work well within a team.
My Github profile with some open source work: https://github.com/GDay. I maintain a fairly popular background worker for Django and have open sourced one of my SaaS applications.

Hi! I've been a software engineer for around 7 years. I have experience with both front-end (mostly React), as well as back-end (mainly Python) and I'd be happy to work on either side of the stack (or both) as well as learning new things. The most important thing to me is to create a positive experience for my users.
I also like contributing to free & open-source software. Most of it is available in my GitHub profile: https://github.com/MarcAbonce
I can provide the following for you:
- Product Design — Whether you need a design from scratch, a redesign, or you're having issues with a small part of your product, I can design it.
- Front-end Development — I can build the design into a pixel perfect product. This is rare among us designers and has proven to be extremely powerful for the result since there is less wasted effort. I've worked with a wide range of frontend and backend technologies and can hit the ground running on new projects. I pick up new tech quickly, which makes it easy for me to adapt to different environments.
- Analysis — Your users, know everything that's wrong with your product but have difficulty communicating it. Often it comes out in anger and frustration. That's where my usability analysis comes in. I'll review your app from an outsider and expert point of view, and give you actionable feedback.
- Free advice — You might not be sure if I am the right fit, and I very well might not be. I can help you figure out the best direction to go for free.
I take my work very seriously and put a lot of work into excellent communication, proper planning, and, last but not least, properly understanding your product so that we can produce great results.
