Building data-access actors for OSINT, KYC, and lead enrichment teams.

I run checkleaked.cc and whatsapp-proxy.checkleaked.cc — the infrastructure behind the actors on this profile. Actors are thin, fast wrappers over phone-number intelligence pipelines I've been iterating on for several years: WhatsApp Web sessions, Telegram account resolution, and a curated breach-record index covering Facebook, LinkedIn, Adecco, and other large dumps.

• Phone-number lookup actors — WhatsApp presence, profile pictures for normal users (not just businesses), about/status text, Telegram cross-check, Google / TrueCaller intel.
• Leak-intelligence actors — match a phone number or email against indexed breach databases (Dehashed, LeakCheck Pro, HIBP, FB leak).
• Bulk verification — list-in, enriched-list-out, with concurrency control and pay-per-event pricing.

Each actor is cache-first: repeat queries cost a fraction of a live lookup. Not-found and error results are never billed.

• Pay only for successful results. Failed lookups, timeouts, and numbers not on the platform are free.
• Transparent pricing. Every chargeable event is documented in the actor README before you run it.
• No silent upsells. Premium fields (profile pictures, leak records) only appear — and only bill — when you opt in.
• Bulk-friendly. Actors accept up to 100,000 inputs per run and expose concurrency controls.

TypeScript, Node 20, Apify SDK v3, axios. Backends run on hardened Express services with MongoDB-indexed caches, Redis telemetry, Parquet / S3 cold storage for archived records, and long-running WhatsApp Web sessions orchestrated across multiple devices.
