// selected workSystems shipped and still running.
Six production builds. Each one solves a failure mode that breaks naive automation: the retries, the races, the duplicate that calls the same lead twice, the outage nobody notices for 22 hours, the estate of hundreds of workflows that just has to keep running.

Self-Hosted Rebuild for a Dubai Real-Estate Firm
A DACH-focused Dubai property firm ran about 800 Zapier zaps, with 300 to 400 on sales alone, failing roughly 80% of the time. Retry loops burned through task quota, forced four plan upgrades, and triggered a $9,989 surprise charge. I rebuilt the stack on self-hosted n8n with PostgreSQL and Redis, using queue-mode workers and database-level dedup locks, and consolidated hundreds of brittle zaps into 23 reliable production workflows.

Close CRM · OpenAI Whisper · Claude
AI Sales-Call Quality Analyser
Setters were graded by gut feel, so coaching didn't scale. I built a pipeline that takes every completed call, transcribes it with Whisper, then runs a two-agent Claude system that scores it against a 6-phase sales script and extracts every investor objection. It drops a short and long verdict into Slack and logs it for coaching.

Webhook Fan-Out Collapse: 62% → 0% Failures
Multiple CRM subscriptions to the same event fanned out 7 ways and timed out about 62% of the time, silently dropping leads. I replaced 13 trigger workflows with a single router that dispatches to sub-workflows behind an atomic Postgres lock, killing the fan-out at the source.

"NEVER Twice": Race-Safe Lead Dedup
A single referral once spawned 196 duplicate leads under concurrent load. I designed a 3-layer dedup pattern: a submit-only filter, a pre-create check, and a post-create race resolver that picks a deterministic winner. The same lead can never be created twice now, even under simultaneous fire.
196 duplicates → zero
concurrency-safe across every CRM pipeline

End-to-End KYC & Onboarding Pipeline
Client onboarding meant hours of manual doc creation, signature chasing, and status updates across three tools. I wired it end to end: a CRM trigger fires document generation, a signed-doc webhook updates the CRM and project board automatically, and every stage is deduplicated with a full audit trail.

Lead Routing & Follow-Up Rebuild for a US SaaS Company
A US SaaS company was losing deals to slow, inconsistent follow-up, and leads were landing with the wrong rep. I rebuilt their lead-routing and follow-up engine: instant qualification, territory and source-based assignment, and automated multi-touch sequences that never let a lead go cold.
