Businesses don't struggle because they lack software. They struggle because the software they already use doesn't work together.
I build AI workflow automation that connects your existing tools, eliminates repetitive work, and turns manual business processes into reliable systems your team can trust. Whether it's lead management, internal operations, reporting, CRM workflows, or AI-powered decision making, my focus is always the same: build automations that continue working long after deployment.
Every system is designed with clear business logic, error handling, documentation, and safeguards for edge case, not just a workflow that works during a demo.
Recent Projects
AI Lead Response System – Dental Clinic
The clinic's team was responding to new enquiries in 1–3 hours. I built an AI workflow that qualifies every lead, sends a personalised response within 15 minutes, notifies the team with a structured summary, and supports appointment booking.
Result:
Response time reduced from hours to under 15 minutes
Booking rate increased by 25%
Approximately 15 hours of manual follow-up eliminated each week
AI Voice Agent – HVAC Company
Built an AI voice agent that calls every new lead within two minutes of form submission, collects job details, qualifies the enquiry, and sends the owner a complete summary before they're available to return the call.
The owner starts every conversation already knowing exactly what the customer needs.
Business Workflow Automation
I build workflows that coordinate multiple business systems including CRM platforms, email, calendars, databases, AI models, and third-party APIs.
Typical automations include:
Lead qualification and routing
CRM and database synchronisation
AI-powered document processing
Customer follow-up sequences
Internal approval workflows
Reporting automation
Email and communication workflows
API integrations between existing business tools
Technologies
n8n • Make • Claude API • OpenAI • Google Workspace • Airtable • Notion • GoHighLevel • HubSpot • Twilio • Vapi • Gmail API • Shopify • REST APIs • Webhooks
How I Work
Every project begins with understanding your existing workflow before writing a single automation.
I deliver in clearly defined milestones so each stage is reviewed, tested, and approved before moving to the next. Every workflow is built with reliability, maintainability, and future expansion in mind.
You'll receive clean documentation and a system that your business can confidently operate after handof, not an automation that only works while I'm watching it.
If you'd like to see examples of similar systems, I'm happy to walk you through a live demonstration and explain the architecture behind each solution.

Most AI freelancers stop at the model. I build the entire product around it backend, dashboard, authentication, billing, permissions, logging, human review, and deployment so what you get is a system your team can actually run, not a prototype that dies after the demo.
𝐖𝐡𝐚𝐭 𝐈 𝐁𝐮𝐢𝐥𝐝:
AI Agents & Multi-Agent Systems: Autonomous and multi-agent workflows using LangChain, LangGraph, CrewAI, AutoGen, Semantic Kernel, and OpenAI Swarm/Assistants API, integrated with MCP for tool-connected agents that automate customer service, data processing, and internal operations.

Inference optimization with vLLM, TGI, TensorRT-LLM, Ollama, llama.cpp, and Groq, plus quantization (AWQ, GPTQ, GGUF, GGML, bitsandbytes) for cost-efficient deployment.
Workflow Automation: End-to-end automation of follow-ups, data entry, reporting, and document handling, connecting disparate systems via API integrations and no-code/low-code tools like n8n, Make, Zapier AI, Flowise, LangFlow, and StackAI.
AI SaaS & MVP Development: Full product builds from idea to deployed system authentication, billing, dashboards, and the AI layer fully integrated and ready to hand off. I also take on rescue projects: refactoring, hardening, and shipping half-built MVPs that stalled with a previous developer.

Built to scale and to last: every deliverable is designed with security, reliability, and enterprise-grade workloads in mind from day one.
Clear scoping: I scope the first milestone realistically, build it without overengineering, and ship something you can actually use and iterate on.
If you need AI added to an existing product, a workflow automated end-to-end, a voice agent handling your calls, or an MVP taken from idea to deployment, I'm ready to scope the project and get started.

I help growing businesses turn scattered tools and manual workflows into structured, automated systems that scale with their operations.
My work focuses on designing reliable data infrastructures and workflow automations that eliminate repetitive tasks, improve data accuracy, and give teams clear visibility into their operations.
I specialize in building systems using Airtable, Make (Integromat), Zapier, APIs, and modern no-code/low-code tools, combined with traditional database architecture principles. The result is a system that is not only functional today but maintainable and scalable for long-term growth.
Whether you need to restructure an existing database, automate complex workflows, or build a complete operational system from scratch, I design solutions that are clean, reliable, and production-ready.
⸻
What I Do
I design end-to-end operational systems that connect data, processes, and people.
Database Architecture & Optimization
Designing structured relational databases using Airtable, PostgreSQL, and SQL/NoSQL systems with a focus on performance, scalability, and maintainability. I specialize in cleaning up messy databases and building clear relational data models.
Workflow Automation & Integrations
Building powerful automations using Make (Integromat), Zapier, Google Apps Script, and APIs to connect your tools and automate processes. This reduces manual work, prevents human errors, and ensures data flows smoothly between platforms.
Internal Tools & Client Portals
Creating internal dashboards, admin tools, and client portals using Softr + Airtable, enabling teams and clients to interact with data through simple, secure interfaces.
Data Collection & System Inputs
Implementing structured input systems using Typeform, Jotform, Tally, and custom forms that feed validated and organized data directly into centralized databases.
AI-Enabled Automation
Integrating AI-powered workflows (including ChatGPT and AI APIs) to automate data processing, generate insights, and support smarter decision-making across your systems.
⸻
How I Work
Every project begins by understanding your business logic, workflows, and data dependencies.
From there I design systems that are:
• Simple for teams to use
• Reliable in real-world operations
• Automated wherever possible
• Flexible enough to grow with your business
My goal is not just to deliver a setup, but to build well-architected systems that quietly run in the background, saving time, reducing operational risk, and creating long-term efficiency.
⸻
If you’re looking for someone who can design databases, automate workflows, integrate tools, and future-proof your systems, I’d be happy to collaborate.
