AI Agents

AI WhatsApp Lead Capture

Business cards and voice memos → structured CRM leads, in seconds

Trade show lead collection via WhatsApp. Business-card photos processed by GPT-4o Vision; voice memos transcribed by Whisper and parsed for sales context. AI duplicate detection handles OCR noise, confidence scoring flags uncertain records, and plain-English error replies guide the sender at every step.

AI Agents

Multi-Channel Campaign Generator

One brief → on-brand copy and visuals for 7 channels, simultaneously

A campaign brief generates content for every channel at once: web hero, push notifications, email, social carousels, and video reels. Channel tone and formatting rules live in a database, editable without a redeploy. Human approval step before anything goes live.

Embeddable RAG Support Chatbot

One line of HTML → knowledge-base chatbot with live rollout control

Support chatbot with RAG retrieval over a custom knowledge base. Conversation logging, low-confidence escalation to human agents, a kill switch, and gradual percentage rollout. All controlled remotely without touching the codebase.

Workflow Automation Suite

Four connected automations replacing manual ops across an entire business

End-to-end n8n automation for an online education provider: AI coursework marking (submission → GPT assessment → Slack delivery with per-format routing), a document conversion microservice on Cloud Run with magic-byte file detection, cross-platform payment-failure handling with deduplication and idempotency, and a coaching call replay pipeline.

Auditable Product Selector

Every product recommendation traces to a signal score. Zero gut-feel picks.

Replaces manual product curation for email campaigns with a scored, traceable shortlist. Each recommendation links to a signal value: sales velocity, margin, recency, seasonality, stock level. Weights are hot-editable. An LLM only writes the 'why' sentence; a human approves or swaps before send.

Distributor Performance Dashboard

150 global distributors tracked with ERP sync that never overwrites human judgment

Web app for a B2B sales team managing a global distributor network. Live sales figures sync read-only from ERP; ratings, notes, and focus priorities are stored separately so a data refresh never overwrites human input. Computed growth targets, traffic-light signals, and a print-ready export.
