Minions.AI Voice

AI voice receptionist for trade contractors, built on Retell AI + n8n. Books real appointments end-to-end (Google Calendar + EspoCRM), with a multi-slot conversational intake and an in-memory availability cache that replaced a 1,272ms cold Google Calendar lookup with a <50ms cache hit. Live for a pest-control client (Ironclad Pest Solutions) and a real-estate variant (Horizon Realty).

Average booking call cut from ~3m40s to ~2m18s.

Measured across the 45 most recent live calls on the pest-control booking agent. Each booking writes a linked Calendar event, EspoCRM Contact and Opportunity.

Minions.AI Content Engine

Automated content pipeline for trade-contractor marketing: a 4-stage Qwen (DashScope) workflow drafts, edits, and reformats blog and social copy, gated by a claims-checking step before anything publishes. The gate blocks any unsourced claim outright — including a hardcoded rule against fabricating customer results, since there are no paying clients yet to attribute them to.

Claims gate blocks unsourced stats from auto-publishing.

GenMorphics AI

Full-lifecycle enterprise workforce management platform for GenMorphics AI Solutions. A single system of record replacing spreadsheets — covering domain-expert onboarding, skill-based task routing, a custom-built NDA lifecycle engine, database-driven access control, and automated payroll for a global contractor base.

Replaced spreadsheet-run contractor ops with one system of record.

Client Proof & Impact

Measurable outcomes from the founders we've built with.

“Parvej doesn't just build websites — he genuinely thinks about cost-efficiency from the client's perspective. Two things stand out: he always over-delivers beyond what he commits to, and he delivers ahead of schedule. For non-technical founders looking for someone you can 100% trust with your platform, I highly recommend Parvej.”

“I had the opportunity to work with Parvej and the website team during the development of the CPRBD website. Parvej was professional, responsive, and committed throughout the process. He and the team were receptive to feedback, handled website requirements effectively, and worked collaboratively to turn our ideas into a functional and professional web presence.”

“What I particularly appreciated was their willingness to understand the programme’s needs and make improvements accordingly.
