PROJECT OVERVIEW I’m building a financial stock news screener focused initially on UK (AIM & Main Market) and then later US small-cap stocks.

I’m looking for one capable individual developer (not an agency) who can own the technical implementation and iterate with me as the logic evolves. Where necessary, I want the option to work side-by-side in person for short periods, so UK or Europe location matters.

NICE TO HAVE (NOT ESSENTIAL) - Experience with financial markets, trading, RNS or SEC filings - AI / LLM-based text classification - Elasticsearch or similar search tools - AWS or cloud deployment - Previous SaaS or data-platform builds LOCATION REQUIREMENT (IMPORTANT) You must be based in or near one of the following: - UK - Spain - Western or Southern Europe (easy travel to UK or Spain) Due to the likely evolving nature of the project I want the option to meet in person and potentially work together for short, focused periods if required. Please clearly state your location when applying. ENGAGEMENT TYPE - Individual freelancer only (no agencies) - Long-term potential if the fit is right - Paid hourly or milestone-based (open to discussion) HOW TO APPLY (VERY IMPORTANT) To avoid generic applications, please include: 1. A short description of a similar data-driven or API-heavy project you’ve worked on 2. Your primary tech stack 3. Your current location 4. Your hourly rate 5. Confirmation that you are open to occasional in-person collaboration Applications that ignore this will not be considered. WORKING STYLE I’m an equities/indices trader with 30 years experience, reasonably technical but not a developer. I value clear thinking, no nonsense honest communication, and someone who challenges bad ideas rather than blindly coding them.

Engagement model - Several hours per week. - Ongoing during core development - Paid hourly or retainer What I expect from you - Direct, honest feedback - Willingness to push back on bad implementations - Comfort enforcing specs over opinions When applying Please include: - Your background in code review / technical leadership - An example of a project where you prevented a costly mistake - Your availability (hours per week)
