Most companies I work with are running on Excel sheets, email threads, and CRMs stretched to do things they weren’t built for. I replace that with real internal systems. Ops portals, dashboards, workflow automation, and then layer AI on top where it actually earns its keep. I’ve done this end to end for a Canadian telecom operator. Activations, port ins, moves, DID inventory, all moved off spreadsheets into a central operations system with role based access, audit logs, escalation flows, and CRM integration. Before that, across a university covering HR ERP, archive, publishing, media. Writing FRDs, designing workflows, delivering systems. On AI, I build automations that take work off people’s desks. LLM pipelines using OpenAI GPT and Claude, RAG, n8n workflows and custom AI agents. Lead gen pipelines that search, scrape, qualify, and draft personalized outreach. Content generation with multi platform publishing. Voice to text using Whisper. GPT powered analysis inside shipped products. When a mobile or web app is the right answer, I ship that too. Senior Flutter engineer on ScreenCoach, running on five platforms from one codebase across Android, iOS, Web, macOS, Windows for an Australian startup. CarbonVoice with complex real time animation for a US startup. Matchark in the UK. Also AI native products like Voice Journal AI using Whisper, GPT, and RevenueCat. Top Rated Plus on Upwork. 100% Job Success. 70K+ earned. 2,100+ hours. What I lead on: • Digital transformation of operations. Replacing manual workflows with internal systems. Admin portals, approvals, dashboards, audit logs, role based access, and integrations with your CRM, ERP, and other tools. • AI automation and AI agents. LLM, RAG, OpenAI, Claude. Lead generation, content, qualification, document processing, internal workflows. If someone is doing the same thing twice, I take it off their desk. • Workflow automation. Approvals, notifications, escalation flows, cross system sync. If the process lives across tools, I connect it. • Mobile apps. Flutter across Android, iOS, Web, macOS, Windows. Firebase, REST APIs, RevenueCat, Stripe, real time sync, push notifications. • Web systems. Node.js, React, TypeScript, PostgreSQL, Firebase. Admin dashboards, internal portals, SaaS MVPs, offline capable systems, real time backends with WebSockets. • Requirements and system design. FRDs, acceptance criteria, workflows, low fidelity wireframes. Useful when the client is not fully clear on what they need yet. If you are running operations on spreadsheets and inboxes, or you have a team doing the same work again and again, we should talk.
