Available for Principal Unity UI-based App/Game Development, Gaming Backends, and UI/UX Design Opportunities – One-Man Army from Concept to Launch
I’m currently available for on-site/remote roles worldwide, as well as remote opportunities in Unity UI (uGUI, UI Toolkit) based App/Game Development, including gaming backends and UI/UX design. As a one-man army, I have a proven track record of taking projects from concept to launch across desktop, mobile, and web.
Here’s a summary of what I’ve been working on over the past 5 years: www.linkedin.com/posts/manofspirit_opentowork-activity-7237722209241214977-U3ZG
As a versatile designer and developer, I’ve created UI-based 2D games and applications with multiplayer features, ranging from XR-based Metaverse app WeDream to the NASBA-accredited educational app Earmark CPE, to Scrabble-inspired UGC-based Word Game, and even Ludo and Bonza-inspired puzzle games across various platforms.
Starting with GameSparks (RIP) in 2014, I’ve since worked with BrainCloud, PlayFab with Azure Scripting, Epic Online Services, and most recently started exploring Xsolla Backend (AcceleratXR). I’ve built fully integrated BAAS games and apps that often include async multiplayer, user-generated content (UGC), social integration (friends, messaging, etc.), tournaments, achievements, leaderboards, and monetization strategies (in-app purchases, subscriptions, virtual currencies, sales, ad mediation, etc.). Additionally, I’ve developed Unity-based admin tools for seamless management of users, content, and reporting.
On the UI/UX side, I started with Adobe Photoshop 8 and CorelDraw 9 almost 20 years ago; today I design beautiful applications and 2D games while utilizing my development skills to automate design tools for bulk art generation, variations, and solving repetitive tasks. I also leverage AI tools like MidJourney to push beyond creative limits.
Even though my focus is on the design and development of backend-driven Unity-based apps/games, my diverse skill set and ability to wear multiple hats allow me to seamlessly contribute to every stage of a project—from initial concept and UX design to backend integration, multiplayer systems, and final launch. This versatility enables me to adapt to different roles and challenges, delivering comprehensive solutions that align with the project’s goals.
If you have any openings that align with these diverse skills, I’d love to connect and explore how I can contribute.
I am a Senior QA Automation Engineer with 12+ years of experience in Software Testing in an Agile environment. I have hands-on experience in all software testing life cycle stages, including both Manual and Automation testing.
I am seeking part-time or full-time contract work as a QA Automation Engineer. I prefer long-term commitments, but I am also available for smaller projects.

I can provide the following for you:
- 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.
- 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.

Unicorn. I do branding [1], design, and full-stack JavaScript development. I built the Joystick JavaScript framework (full-stack [2]) and Push deployment service [3]. Recently shipped Parrot [4].
Looking to work with entrepreneurs and small teams (or VCs who need a sharp shooter who can deliver) who need help shipping product and features that work from day one, fast. 17+ years of experience running a small business/shipping software, so I don't need to be babysat—just set loose with a clear idea of what needs to be built and open lines of communication if/when I have questions. The catch: using freelance work to finance product ideas and have freedom to do work on my terms (i.e., I can be available to consult long-term but not looking to transition to a full-time position).
Average time to brand, design, and ship a full-stack app is 3-6 months but I can move faster if you're willing/able to delegate 100%.

Like this Ask HN: Recommend employers with positive social impact [https://news.ycombinator.com/item?id=31518945], I am looking for similar work. I am a European software developer who has lived and worked on four continents. Now it's time to move on and so I am in the process to relocate to Africa.
While I could find a job elsewhere I believe that the experience living in an area where my work is going to have an impact gives me a better understanding of the needs of the location I am serving. Whether it is through direct contact with clients and users or just by being part of a local community and learning about the reality of living there.
I have more than a decade of experience running a company, doing software development, support and training and mentoring adults and students, as well as working on educational projects, and I am willing to take on a mixture of roles as needed to support a project.
I am also open to work for companies anywhere as long as the work can be done fully remote from Africa.
In addition, my plan to use some of my income to hire local interns and junior developers and train them in order to pass on my experience. If you want to support this, I would love to work with you. Also if you are interested in hiring African developers yourself. I can help you build up your team.

SEEKING WORK - Data scientist, remote worldwide, email in profile.
All I want for Christmas is a good problem to noodle on over the holiday (and beyond).
I'm a data scientist and I've been absolutely slaughtered by this recession. I lost a big project in July and haven't picked anything up since. Everything is "on hold until new year". So I'm looking for a project or it's coal for Christmas.
I love avant garde problems, and have a pretty unique toolset (LLMs+KB, OR+ML, etc). I've worked with names you know in automotive, tech, and other spaces.
I've worked on projects including large language models, knowledge extraction, automotive part failure prediction, translation, maintenance optimization, automated sports highlights, and more. I've also done some more interesting work including vehicle route planning in constrained environments.
My calendar is currently empty this holiday, I'm willing to do what it takes to fill that up. Get in touch. Even if you're unsure, get in touch. Referals welcome. Email in profile.
While I'm familiar with various technologies, my passion lies in programming with Rust. Whether it's backend development, blockchain, compilers, DevOps, embedded systems or mobile applications, I am totally onboard as long as there is a little bit of Rust involved.
For more information, take a look at my CV (https://c410-f3r.github.io/curriculum.pdf) or my GitHub account (https://github.com/c410-f3r).
I'm a software engineer and designer with 2 decades of experience across a wide range of industries, from B2B factory-floor logistics to language design to cute consumer web apps. I specialize in helping small teams solve tricky technical and process problems, quickly. Is your team not delivering as fast as you expect? Are you dealing with more bugs or more setbacks than you think you should? Is there some tricky architectural or design problem you can't crack on your own? I can help push your codebase and your team to improve, so that you'll be running on greased rails even after our contract is done.
For people using text search, here are some of the technologies I'm comfortable using:
AngularJS, Angular, AWS (S3, Lambda, RDS, &c.), C, CSS, Creative Cloud, Flask, git, mercurial, svn, darcs, Glamor, GCS, HTML, Javascript/ECMAscript, Lisps of many varieties, Next.js, Photoshop, Python, Ruby on Rails, React, Ruby, SASS, SCSS, Svelte, Swift, Typescript, Vue Check out me, my projects, and my writing at https://sambleckley.com, or reach out to sam@sambleckley.com
