Clay Expert needed for Consultancy
We hired Sonny as we needed expert consultancy on how to harness Clay and n8n to automate some key recruitment processes within our client's business. He was very hands on, helping us set up new automation flows and tools to save our client time, money and frustration while driving growth in key metrics. It opened our eyes to many possibilities and we are sure this will become an invaluable part of our client's candidate and client acquisition strategy going forward. Sonny is down to earth, easy to get on with and communicates clearly and effectively. I would have no hesitation in hiring him again.

Cardiff, United Kingdom - 8:43 pm local time
Certified Attio Expert Implementation Partner!
Your GTM strategy is only as good as the data that drives it. As a GTM Engineer, I build the production-grade data infrastructure and AI-powered workflows that turn disconnected revenue teams into predictable growth engines.
I architect and implement data-first solutions for high-growth B2B and enterprise teams. Recent results:
• A £750M+ turnover international recruitment group. I built a candidate sourcing and outreach engine that turns a single job description into hundreds of good-fit candidates in minutes, then automatically reaches out to the hiring manager with the strongest matches.
• A $50M ARR SaaS business. I lifted CRM data accuracy past 95%, built automated research reporting that cut 10+ hours of BDR work down to minutes, and created a system that generates personalised landing pages at scale.
+ What makes my approach different
Most RevOps consultants manage the systems you already have. I build new ones. With 10+ years of real technical depth, I use Python, SQL and data science libraries (pandas, scikit-learn) to build custom data pipelines, advanced CRM enrichment workflows, and lead-scoring models from the ground up. I design and build the centralised databases (PostgreSQL, MySQL) that GTM and RevOps teams need to operate at scale. When no-code tools like Clay and n8n hit their limits, I write the code that pushes things over the line.
+ What I build
Attio implementation and migration. I set up Attio properly from day one, or migrate you off Salesforce, HubSpot or Pipedrive without losing history or breaking your pipeline. Clean data model, the right attributes, automations that match how you actually sell.
CRM enrichment and data engineering. Multi-step, cascading pipelines that validate, clean and enrich your CRM data from dozens of sources. This goes well beyond basic enrichment. I design systems that hold 95%+ data accuracy at scale, so your sales team can act on every record with confidence.
GTM and RevOps infrastructure. The full technical stack for your go-to-market motion: automated lead scoring, territory management, attribution tracking, pipeline analytics and forecasting dashboards. Every system builds toward a single source of truth for your revenue data.
AI-powered workflow automation. I design and deploy AI agents and custom workflows using Python, n8n and Claude and other LLM APIs, automating lead qualification, personalised outreach, intent-data analysis and CRM maintenance.
Data pipelines and database architecture. ETL and Reverse ETL pipelines that connect your GTM tools into one unified ecosystem, with custom databases as a single source of truth, staging environments for CRM data, and reporting layers for executive dashboards.
+ Background
• 10+ years in data and technology roles with organisations including BT, GE Oil & Gas, InnovateUK and Confused dot com
• Computer Science degree from Cardiff Metropolitan University, including a data science secondment at Fontys University of Applied Sciences in the Netherlands
• Accredited in Data Science and E-commerce Development
• Expert-Vetted: Top 1% of talent on Upwork
+ How I work
Every engagement starts with a focused consultation to define your goals and the outcomes you want. You get clear communication, regular updates and full documentation. My work is tested, scalable and built to run long-term, not a quick fix.
If you are a revenue leader who needs to move beyond off-the-shelf tools and build a scalable, data-driven GTM machine, send me a message. I will come back to you promptly with ideas on how we can solve your specific challenge.
