Full-Stack & Cloud Engineer

Own the cloud platform behind an AI-powered creator/social product — AWS infrastructure, PostgreSQL/Supabase backends, Next.js frontend features.
Built an event-driven media-processing backbone in AWS CDK: SQS → Step Functions → ECS Fargate pipelines with compute tiers routed dynamically by file size.
Shipped adaptive video streaming end to end — HLS/DASH via MediaConvert, delivered through CloudFront.
Designed a custom OAuth2 auth system minting ES256 JWTs through Supabase JWKS, letting external apps query the database directly with no auth proxy.
Wrote an in-database recommender in PL/pgSQL (freshness decay, co-visitation, creator similarity) powering the For-You and Discover feeds.
Built a priority-tiered async AI media-generation pipeline integrating Gemini and xAI Grok with automatic failover.
Implemented the coin economy (wallets, histories, expiry), referral system and web-push notifications, plus admin dashboards and creator tooling.
