The football game where you control the ball, not the players: dribble past opponents and shoot. Live since June 2019. The lifetime downloads come from the publisher’s user acquisition, not from me; I have been its sole engineer since mid-2024.
Highlights
- The full live-ops loop on my own: A/B test planning, features, rollout, analytics, go or no-go
- Spotted a build that shipped with ads disabled on the dashboards; partial rollback and a same-day hotfix
- About 400k daily players

A roguelike arcade shooter: deal a lot of damage, knock monsters back and blast them. Released on iOS in January 2019. Its multiplayer demo later became the test bed for a research grant (see Pocket Blaster Multiplayer).

A colour-matching puzzle game for mobile: a wall of coloured bricks sits above a grid of builders, and you tap builders to send them, through a short row of waiting slots, to the bricks of their own colour. Each cleared wall goes into a house, and a finished house unveils the next one to build. Built at Orbital Knight in Unity and published on Google Play by Orbital Knight.

An arcade fishing game for mobile: you steer a small boat around a netted pond, scoop up the fish, and trade the catch for coins by filling the villagers’ orders. Coins go into better gear; a diving mode sends you down a reef shaft for rarer species, and a home aquarium holds what you have found. Built at Orbital Knight in Unity and published on Google Play by Orbital Knight.

An action game for mobile, built at Orbital Knight in Unity as a prototype for the publisher SandSoft, who soft-launched it. Seen from above at an angle, a homeowner with a blaster defends a suburban lawn against UFOs that beam down waves of cartoon alien enemies, with damage numbers and pickups on the grass. The game is no longer on the store; the art here comes from a mirror copy of its old listing.

A mobile game in two halves, built at Orbital Knight in Unity as a prototype for the publisher SandSoft (the store listing names QuickSand Games), who soft-launched it. An astronaut digs through underground rock for resources, then spends them on turrets, shields and a rocket to hold a domed moon base against growing waves of dark monsters. The game is no longer on the store; the art here comes from a mirror copy of its old listing.

A top-down arena game for mobile: you drive a monster truck with a wrecking ball on a chain through a desert full of zombies and score by running them down, racing four rivals on a live leaderboard until the 3-minute round ends. Rounds level the truck up mid-match; between rounds a garage screen holds cars and upgrades bought with the coins and rewards each run pays out. Built at Orbital Knight in Unity as a prototype for the publisher SandSoft, who soft-launched it on Google Play.

A top-down delivery race for mobile: you drive a yellow van around a toy-scale city, pick parcels up from marked bays, stack them on the roof and race three rivals to the glowing Delivery Zone before the round timer runs out; the parcel counter (0 of 50) fills as rounds go on, and the map moves from a suburb to a harbour with cranes and a downtown of glass towers. Built at Orbital Knight in Unity as a prototype for the publisher SandSoft; the ad videos carried the name Cargo Clash and a Google Play badge, and the title is no longer on the store.

Beyond gameplay
Work most gameplay roles never touch, mostly done solo. Dated experience, with measured results from the grant documents.
- E1
A multiplayer backend on AWS, built alone
2 AWS regions with Fargate game servers, 11 Lambdas for geo-routing, matchmaking and autoscaling, DynamoDB fleet state and a build pipeline for four platforms. 2019 to 2022; shipped as a public open-beta demo, not a long-running service.
- E2
Latency, measured
An average round trip of 97.64 ms over 500+ samples, against a 150 ms target, and a record-and-replay test framework that automated every test scenario.
- E3
Anti-cheat by deterministic resimulation
Every planted cheat caught, with 0 false positives, on 25 lab matches (lab conditions).
- E4
Two EU Horizon 2020 research projects
Multiplayer and AR use-cases on EU edge and cloud testbeds: network engine optimisation, a 32-bot load tester, telemetry on AWS. 2020 to 2022.
What games taught me about agents
- 01
Unattended servers became unattended agents
Matchmaking and autoscaling had to work at 3 a.m. without me. So does an overnight agent run, and the same things matter: logs, limits and a way back.
- 02
Frame budgets became context budgets
A mobile frame gets a few milliseconds on a cheap phone. An agent session gets a context window; I measure what's always loaded and cut what doesn't earn its place.
- 03
Release checks became verification
Nothing shipped until it passed QA and review. An agent's task isn't done until a test, a diff or a screenshot says so.
