A competitor-intelligence SaaS that monitors competitor pages on a schedule, diffs content changes via SHA-256 hashing, and uses GPT-4o-mini to classify signals and surface recommended counter-moves.

Engineered a smart scraping fallback: Cheerio handles pages natively while ScrapingAnt fires only on failure, intentionally blocking calls to sites like Facebook/Instagram that reject scrapers to minimise API spend.

Designed CronLock (30-min TTL) + pLimit concurrency to eliminate duplicate pipeline runs, a pre-mark pattern on digest emails to prevent duplicate sends under crash conditions, and a full Stripe billing lifecycle with tier-based feature gating across Free, Solo, and Team plans.

A full-stack pet competition platform with a decoupled Next.js + NestJS architecture - contests, leaderboards, voting packages, and prize withdrawals.

Architected vote processing with BullMQ + Redis, then deliberately stripped Redis from Railway prod and replaced it with sync processing plus opt-in Redis config, keeping the system extensible without mandatory cost overhead.

Integrated Stripe for vote purchases and prize withdrawals, with an admin moderation pipeline for pet approval and withdrawal processing.
