You will get a working web app or SaaS MVP built fast with Next.js + Supabase
Project details
I design, build and ship production web apps solo. Not unreviewed AI output: I build AI-first with Claude Code to move fast, then review every line so what you get is real, working, secure software.
My own shipped proof: CVBetter, a live UK SaaS on Next.js, Supabase and Stripe, and two apps live on Google Play. So I am not learning this stack on your budget. I have shipped it.
What I build: marketing and landing pages, full SaaS MVPs with user accounts, databases, Stripe billing and dashboards, all deployed and handed over with the code in your own GitHub. Clean commits, row-level security, no leaked keys, no lock-in.
I tell you honestly what is realistic in the package timeframe before we start. Three fixed-price packages below, or message me for a custom quote or a Flutter mobile build.

Lead Generation for the Embroidery Industry.
Leon was great to work with. He handled lead generation for the embroidery industry professionally and delivered exactly what was needed. Communication was excellent throughout the project: clear, consistent, and proactive, which made the whole process smooth and stress-free.
This was a fixed-price contract, and Leon met expectations on both quality and reliability. I’d definitely recommend him and would be happy to work with him again.

Job Success
Albrighton, United Kingdom - 9:15 am local time
My background is in data intelligence. I built my own infrastructure processing millions of UK company records across Companies House, the ICO register, Land Registry and the PSC register. The same methods I use on that scale, systematic cleaning, enrichment, trend analysis, anomaly detection, are what I bring to client work.
What I do:
- Data analysis and reporting: explore a dataset, surface the patterns, write up the findings in plain English with charts. Suitable for one-off questions or ongoing tracking.
- Data cleaning and structuring: deduplicate, normalise, fix types and formats, output a file ready to import into a CRM or analyse in Excel. Same logic I apply to millions of rows.
- Lead data and B2B intelligence: UK company lists with verified contacts, sourced from public registers and SMTP-verified. No Apollo exports.
- Custom Python pipelines: scrapers, enrichment workflows, data joins across multiple sources.
I work in Python (Pandas, Matplotlib, requests, BeautifulSoup), SQL, and Excel. I deliver in whatever format you need: CSV, Excel workbook, PDF report, SQLite, or a Python script you can rerun.
If you have data that needs thinking, not just clicking, message me and I can scope it in five minutes.
