You tell yourself one more issue before bed. Somehow it's 4am and you're 20 commits deep, solving bugs you didn't know existed.

I am a software developer who enjoys bringing ideas to life. I like taking something that starts as a concept and shaping it into an interactive experience that people can use and enjoy.

I care about building software with intention, where design, functionality, and user experience come together. To me, quality comes from creating clear and intuitive experiences, avoiding unnecessary complexity, and making sure every part of an application serves a purpose.

const developmentPrinciples = {  create:   'bring ideas to life through code',  design:   'make software feel natural to use',  simplify: 'less noise, more value',  craft:    'polish the details that shape the experience',  build:    'solve real problems with thoughtful solutions',  balance:  'functionality and aesthetics work together',  iterate:  'good products are refined, not rushed',  mindset:  'quality over quantity',}

The work
I’ve done.

02 — Selected work

01 / 03

Gestal.gg

A community site for Raid: Shadow Legends. It holds the records for over a thousand champions with deep filtering, alongside tools for tracking in-game events. Content creators can upload their teams with the full detail of how the stats were reached. The goal is a single hub of information for the Raid community.

The Gestal.gg champion index in a browser: faction crests, affinity and role filters, and a grid of champion cards.
01 — Sidebar navigation A persistent rail holds champions, teams, fusion, calculators and the desktop build, so no tool is a separate site.
02 — Responsive design Built with responsiveness in mind, so the site works on every screen size, from phone to desktop.
03 — In-game cards recreated Rebuilt as they look in game, so you recognise rarity, affinity and aura immediately.
04 — Loads as you go The first champions load with the page and the rest arrive as you scroll.

Gestal Desktop

A desktop application that talks directly to the Raid: Shadow Legends process running on your PC. That means it can read the data for your own account and call in-game functions. The main features are the gear optimizer, team presets and the armory. We support this application on Windows and macOS.

Uses either CPU or GPU to solve an optimization problem, going through the gear on your in-game account and searching for the best build it can find based on your goals and priorities.

Gestal · Optimizer
Gestal Desktop gear optimizer: stat goals and mode on the left, the top build on the right with its nine pieces, set bonuses and the gain over the current gear.
01 — The best build found The highest scoring build the search found, with every stat compared to the gear currently equipped.
02 — Stat goals A priority, minimum and maximum per stat. The priority sets what the build focuses on, and only builds that meet the limits are returned.
03 — Equip in game Equips the chosen build in the game directly, without swapping the pieces by hand.
04 — Optimisation mode Three modes to optimise for: priority, damage or survivability.

Save presets of your champions. This saves what gear you have equipped on them, allowing you to easily put the exact gear back on.

Gestal · Team Presets
Gestal Desktop team presets: a General category holding a Main PVE preset of three champions and a PVP preset of one, each card carrying equip, edit and delete actions.
01 — Import from game Creates a preset from the team currently equipped in the game.
02 — Categories Presets are grouped into categories you create and name.
03 — Champions and gear A preset stores the champions together with their gear.
04 — Already equipped A preset that is currently equipped in the game is highlighted green.

An overview of all the gear on your account. Through the armory you can upgrade and sell your gear. It provides a customizable scoring system.

Gestal · Armory
Gestal Desktop armory: 3,473 artifacts grouped by set, every piece scored, with slot, rank, rarity, level, score and state filters down the left.
01 — Sell filters and scoring Both the sell filters and the scoring system are fully customizable.
02 — Filters Narrows the pool down to the gear you are looking for.
03 — Score Every piece carries a score. Gear that is not levelled shows only its potential score.

Raidle.today

A daily champion-guessing game for Raid: Shadow Legends, with six modes and one puzzle a day. It runs on the same champion data as Gestal.gg. The puzzle is derived from the date, so every player gets the same champion on the same day.

raidle.today
Raidle in classic mode: a grid of guessed champions with every attribute column marked correct or incorrect.
01 — Daily game countdown Everyone plays the same game. Every 24 hours a new champion is picked at random for each game.
02 — Game types Six different games to play. Classic guesses on attributes, and the others start from the description, skill, emoji, silhouette or splash art.
03 — Clues Clues unlock after a number of tries. Each one shows how many guesses are left before it becomes available.
04 — Green and red Green marks an attribute you guessed correctly and red one you did not. You use them to work out the correct champion.
Raidle on a phone: the mode switcher and daily countdown above the clue cards, with the attribute grid scrolling sideways below.
