Fitness & workout-tracking platform · 60K+ users

Mobile workout-tracking platform with social feed, progress analytics, and paid subscriptions. I built the entire backend solo.

• ▹Solo Node.js + TypeScript/Express backend: workout logging, custom programs, PR tracking, social feed, Stripe subscriptions, admin panel
• ▹Scaled to 60K+ users with zero downtime and stable latency
• ▹Composite index on user_workouts cut query time from ~4s to ~200ms
• ▹Redis caching for leaderboards; fixed N+1 in the social feed endpoint
• ▹Migrated heavy cron jobs to background services, eliminating overlap issues
• ▹CI/CD via GitHub Actions → AWS Elastic Beanstalk + RDS, fronted by Nginx + Redis

• Node.js
• TypeScript
• Express
• TypeORM
• PostgreSQL
• Redis
• Stripe
• AWS

• ▹Automated background jobs for payouts, reminders, and cleanup
• ▹Still active with hundreds of paying users and ongoing revenue

AI pipeline that turns discovery notes into spec + handoff docs

A CLI tool that reads raw client discovery material and generates client, designer, and dev-handoff documents through a two-stage Claude pipeline — productizing the Spec-Driven Development workflow I drive across my team.

• ▹Two sequential Claude calls: raw input → internal SDD + designer brief → final client/design/dev outputs
• ▹Validates generated docs for structure, feature coverage, and design-to-dev token consistency before writing
• ▹Encodes Spec-Driven Development as repeatable tooling, not just process

• Node.js
• JavaScript
• Claude API
• LLM agents
