under load.

• —Built a dedicated Elasticsearch thread index to replace query-time field collapsing, cutting inbox API latency and eliminating O(N) scans across 95+ rollover indices.
• —Designed Lead-Finder: a cost-optimized waterfall across multiple email-finding providers with idempotent webhook verification, cutting cost per verified lead 30–40%.
• —Shipped a real-time visitor identity pipeline (tracking script, Kafka, BullMQ) turning 50K+ daily events into enriched B2B profiles with live intent scoring.
• —Led full product revamps of ReachInbox and Zapmail — UI, core workflows and platform architecture.

• —Built Ant-Affiliate, a full-stack platform where users sell financial services and earn commissions.
• —Wrote the commission ledger APIs — admin credit/debit flows on Laravel 12 with JWT authentication.
• —REST services with strict validation, error handling and full transaction history.

A terminal-native SQL client for Postgres, MySQL and SQLite built in React (Ink). Queries run against each native engine with no intermediate planner — 75MB resident against 1GB for Electron and JVM clients. Real cancellation via AbortController driving driver-level cancel, AES-256-GCM encryption for saved credentials, and a hand-rolled multi-tab editor with cursor tracking and live schema validation.

A microservices pipeline for upload, transcoding and adaptive streaming. Chunked uploads land in S3 and emit Kafka events; a transcode service converts to HLS with FFmpeg for adaptive playback.
