Full-stack developer, data scientist, engineering manager and gamer. I build software, find out what the data is saying, run the teams and operations that keep both going, and play the games I end up building tools for.
What I do
Build
Full-stack development
Web applications from the database to the last pixel: typed APIs, data models that survive change, and interfaces people can use without a manual. I care about tests that catch real regressions and pages that load fast on a phone.
Measure
Data science
Turning messy sources into numbers you can trust: extraction pipelines, clean datasets, models and simulations. The goal is always a decision someone can make with more confidence than before.
Run
Engineering management & operations
Leading engineering teams and the operations around them: setting priorities, removing blockers, building processes that scale, and keeping delivery predictable without burning people out.

Project
Slayer Legends Analyzer
A free build planner for the mobile idle RPG Slayer Legends, made by a player. Enter your character, skills, equipment and companions, and the analyzer adds up every stat source the way the game does, so you can see which upgrade moves your power the most before you spend a single resource.
It is also where all three kinds of work meet. A Python pipeline extracts and tests the game data, a typed calculation library reproduces the formulas, and a Next.js interface keeps your profile in your own browser.
Guides
- How to use the Slayer Legends AnalyzerA tab-by-tab walkthrough: entering your profile and resources, reading the Stats Summary, playing a promotion fight, and following its upgrade plan.
- How character stats are calculatedWhy some upgrades multiply your ATK while others barely move it: the grouped formulas behind ATK, HP, spirits, crit, gold, EXP and element damage.
- Enhance, Growth, Promotion and ClassesHow the core character systems scale, with the level thresholds, promotion multipliers, class numbers, Memory Tree and Constellation of Light that matter.
- Skills: power, Mastery, Refinement and ProficiencyHow skill power grows with level, how Mastery, Refinement, Proficiency, Skill Stones and Familiars add to it, and how skills play in a fight.
- Weapons, accessories, relics and spiritsEquip versus owned effects, awakening, relic level bands, spirit levels and partners, soul weapon completion, the Sealed Shrine and the Black Orb, with worked numbers.
- Companions and beastsEllie, Zeke, Miho and Luna's passives, advancement and promotion rolls, how owned and mounted beasts add to your stats, and what beast skills do in a fight.
- Promotion fights: how the simulator worksHow the analyzer estimates a promotion boss, plays the fight with your skills, familiar, beast and spirits, reads the result, and plans the upgrades that win it.
