Measurable Results
Quantifiable business outcomes demonstrating the tangible value of our automation solutions
Instant balanced team generation from player nicknames — zero manual stat lookup or spreadsheet work required
Strategic Impact
Eliminating manual stat lookup and spreadsheet balancing saves 10-15 minutes per match setup, which for regular community events (2-3 times per week) translates to hours of saved organizational effort monthly.
Business Value
Instant team generation removes the organizational friction that discourages community match organizers, increasing event frequency and player engagement.
Challenge & Solution
Real business challenges and our targeted automation solutions
Business Bottleneck
Manual team balancing based on subjective skill estimates resulted in consistently lopsided matches No tool combined real-time Elo data with recent performance metrics for accurate player assessment
Solution Points
Built React 19 + Vite web application with multi-step wizard flow: landing → team count selection → player nickname input → loading → results
Integrated FACEIT Data API v4 for real-time player data: profile lookup, Elo rating, skill level, lifetime stats, and last 30 match history
Developed Bayesian-weighted scoring algorithm combining Elo (50%) with adjusted K/D ratio (50%), using Bayesian prior (weight=10, prior K/D=1.0) to normalize players with few recent matches
Implemented snake draft distribution algorithm that sorts players by composite score and alternates pick direction each round for optimal balance
Built serverless API endpoint on Vercel with batch processing (5 players per batch) and rate limiting (100ms delay) to respect FACEIT API constraints
Created bilingual interface (English/Russian) with React Context-based i18n system and language toggle
Developed results display with color-coded K/D ratios, skill level indicators, team average stats, and balance spread percentage
Implemented responsive design optimized for both desktop and mobile use during LAN events
Added support for 2-10 teams with dynamic player count validation (5 players per team)
“I'm genuinely speechless — this thing is insane. The tool works exactly as needed and completely eliminates the headache we had organizing local and online tournaments. I'm honestly blown away.”
