Founder & Engineer at MessengerFlow

July 1, 2023 - Present

Designed and shipped a multi-tenant SaaS for Facebook Messenger outreach across three services (Nuxt 3 app, Python+Celery worker, Node MCP server), 40+ Postgres tables, and 155 API endpoints. Built a distributed browser automation engine running 15 concurrent stealth Chrome sessions per host with runtime-generated anti-fingerprinting extensions, human-behavior simulation, and a 10-attempt Facebook login state machine handling TOTP, captchas, and identity checkpoints. Created Nexus, an AI-driven account-warming pool managing 150+ accounts on randomized schedules to build credibility before live outreach. Implemented a Postgres-backed job queue with per-account daily limits, multi-level distributed locking, and self-healing recovery; coexists with Celery for 6 task queues. Introduced a distributed circuit breaker with global and per-account thresholds and a webhook delivery system with HMAC, exponential backoff, and automatic endpoint disabling on persistent failure.

Founder & Engineer at ScrapeSpace

January 1, 2025 - Present

Designed and shipped a multi-tenant AI-driven web scraping SaaS where users describe what they want in plain English and an AI agent navigates a real browser to extract structured data (Nuxt 3, FastAPI, PostgreSQL 16, Redis 7, Selenoid, Docker Compose). Built AI agent control loop on Claude Sonnet 4 with automatic escalation to Opus 4 on consecutive failures: vision-first page perception, tool-use loop, loop detection, message-history auto-trimming, and rate-limit retry with exponential backoff. Implemented two-tier Claude API token budgeting for global + per-user rate limits with atomic Redis ops. Generated replayable Playwright Python scripts from successful runs to reduce AI cost. Implemented two-tier self-healing: Claude Haiku for small selector fixes and Claude Sonnet for full-flow rewrites; included full audit log with diffs and tokens. Hardened against prompt injection with system-prompt isolation, HTML sanitizer, and sandboxed JS/Python execution environments. Added Stripe mete
