    Hi, I’m Daniel Spruill: a Unity developer with 8 years of experience, an eye for polish, and a knack for turning side quests into fully developed storylines. I’ve had the privilege of working on some pretty awesome things, most recently Rogue Piñatas: VRmageddon: a physics-fueled VR bash-fest where I was one of the core developers. From building dynamic objectives and VR interactables to implementing boss fights and squashing bugs, I had my hands in nearly every system. Before that, I worked on Pokémon GO, contributing to major features and refactoring legacy systems. I even got to implement some cool features that I unfortunately cannot give further detail about (NDA) Whether it’s games, tools, or interactive experiences, I bring strong communication skills, collaborative energy, and a passion for great player experiences. I’m also an avid board gamer, so balancing systems and designing for fun is second nature. And fun, like really fun. If you're looking for a Unity dev who can jump in fast, ship clean code, and maybe even drop a Hades or Divinity Original Sin II reference in a stand-up meeting, let's chat.

    Since 2016, I’ve been working in Go codebases. In college, I would draft assignments in Go before completing them in a required language. By the time I was applying for jobs, I focused on companies that used Go in production. I was thrilled to work for Pivotal Software. At Pivotal, I stayed on the R&D side of the business for over six years building and shipping Cloud Foundry. I regularly paired with engineers rotating in from the Pivotal Labs side of the business. From veteran consultants, I learned formal TDD, considerate pairing, precision refactoring, and how differing engineering cultures affect technical execution. Over time, I became known as a Go subject matter expert and was often consulted by sister teams for tricky upgrades and performance issues. Outside of full-time roles, I’ve published dozens of open source projects on GitHub and built an investment portfolio analytics website. I also made a YouTube video on deploying Go that has over 6,000 views. I enjoy working with Go publicly and sharing what I learn. While I’ve never held a full-time consulting role, I’ve spent years practicing extreme programming and working closely with expert consultants. I bring deep knowledge of Go and insight into how teams adopt it, where they get stuck, and how they succeed.

I have various projects based around Unreal Engine and Blender for 3D design and Game Development using C++ and Blueprints. I have other projects based around C# and I am currently learning HTML5. My every day work life is constructing quality grade cable assemblies for Aviation, Military, and Medical; I cannot share the contents in specific detail however it involves building assemblies that require extensive knowledge in Cable Design and Soldering to IPC regulations. For more extensive contracts I do have personal work stations for basic soldering and cable assembly/repair provided I am sent the materials and process expected. I am also very happy and willing to try other creators work and help or learn from them given the chance and am experienced in trying betas and helping legal private servers find bugs during production as well as other Unreal Engine Devs with their projects.

    Slow platform? Fragile infra? I help teams fix scaling problems—from broken delivery pipelines to slow, bloated admin systems. You’ve got a platform that’s growing—but your backend is sluggish, your deployments break under pressure, or your analytics just don’t add up. That’s where I come in. I’m Igor—a systems architect and technical consultant with 12+ years of experience helping teams stabilize infrastructure, refactor legacy platforms, and streamline delivery so they can move faster without chaos. ✅ Admin panel lagging or timing out? ✅ Deployments unreliable or rollback-prone? ✅ Hosting migration looming but the codebase is a mess? ✅ GA4 or tracking tools giving bad data—or no data at all? I’ve helped: • Refactor high-traffic WooCommerce and WordPress platforms riddled with years of quick fixes • Migrate legacy infrastructure with zero downtime—even under shaky code conditions • Rebuild analytics systems (GA4, GTM, BigQuery) to give teams real visibility • Cut support and ops workloads by up to 90% through better tools and system automation I work best when things are already messy—whether it’s brittle code, tangled infra, or toolchains slowing everything down. If your platform is blocking growth—or your tech stack is one crash away from a meltdown—let’s fix it.
