03 What I bring

Unity, end to end.

  • 01

    The whole engine

    Gameplay, systems, UI, animation, shaders, tooling, addressables, and the unglamorous work that makes a build ship. Fifteen years. I do not specialise away from the hard parts.

  • 02

    C# that ships

    Clear gameplay code, editor tools, and the wiring between live features. Written to be changed next week, not admired in a vacuum.

  • 03

    Mobile performance

    Hyper-casual lives on low-end devices. Draw calls, fill rate, memory, load times, and the feel of the first ten seconds.

  • 04

    Juice and haptics

    The difference between a prototype and a hit is often the hit-stop, the spray, and the phone buzzing in the hand. I treat feel as a system.

  • 05

    Prototype to live ops

    Fast first playable, then IAP, ads, economy hooks, and the small loops that keep a free-to-play title in market.

  • 06

    Multi-store shipping

    iOS, Android, and Nintendo Switch. Cert, store assets, and the last mile that most portfolios skip.

04 About

Paul Blower

I was the main developer on the games above, not a feature contractor on the edges of someone else's build.

I am 42, from the UK, and I have spent fifteen years inside Unity.

The work is hyper-casual and commercial: games that had to feel good on day one, survive store algorithms, and keep running after launch. Lion Studios, Kwalee, and Playember published them. I built them.

I am available for freelance, contract, or a permanent Unity seat. If you need someone who can open an empty project and come back with a live game, start a conversation.
