Build a verified list of 300 UK B2B companies

I need a meticulous researcher to build a verified list of 300 UK B2B companies for a supplier-sourcing project. This is precision research against a written specification — quality matters far more than speed. A complete step-by-step guide exists for this project: the sectors to cover with exact targets for each, recommended sources and a checklist. The thinking is done — the job is careful execution. The guide is shared only with the freelancer I select. In brief: every company must pass a short set of verification checks every entry needs a defined set of data fields plus proof links, and certain types of company are automatically rejected under our screening rules. Full details are in the guide. Quality control: entries are audited at random against their proof links. Entries that fail will be questioned further. Scraped or AI-generated lists will not pass audit. PRICING: $300 fixed for the full 300 companies, released in stages — a small paid trial batch first, then the remainder as each stage passes audit. TO APPLY: start your proposal with the word LEDGER and briefly describe a similar list-building project you've completed.

Scraping of hungarian insurance data

I have a Hungarian database that's open to the public without any login that I'd like scraped. Unfortunately, this database is extremely slow, tedious, and has "I'm not a robot" checks all the time. This makes it extremely difficult to even scrape it with Claude or any LLM. I'm looking for a creative individual that can pull this data for me and turn it into an Excel spreadsheet. There are going to be hundreds of thousands of data points in here. Please check out the website, and I have a comprehensive list of fields, basically every field that you can have to be scraped. This requires clicking through to the items and, in the majority of the cases, downloading a PDF and parsing that PDF as well. I am open to very creative ideas. Website: https://knyr.mkik.hu/kivreg/nyilvantarto/kereses# I'm also adding a screenshot that is going to help you add a few data points so that you don't have to wait an eternity until it returns the results. Do that because it's going to massively speed up your finding results, but the main project is for every single data point in here. Also, I'm adding a Word document (sorry, but it's in Hungarian), and that carries all the fields that are exposed on this website. I still haven't decided how many of those I will need, and I will work with you to make sure that we can scrape as many as possible.

Supabase Engineer to Review Live Intelligence Platform

We are building a private commercial intelligence platform for the UK logistics and fleet sector. We have already brought together a substantial amount of public, regulatory, financial, property, fleet, licence and operational information covering approximately 64,000 UK fleet operators. The core data is now held in a structured PostgreSQL database in Supabase, with separate records for operators, legal entities, licences, operating locations, fleets, financial history and events. We also have a private GitHub repository and a secure Next.js application deployed through Vercel. We are now looking for an experienced Supabase and data engineer to review what has been built, confirm that the structure, security and source controls are suitable, and identify anything that should be strengthened before the next phase. The next stage is to create a controlled, ongoing enrichment system using APIs, scheduled datasets, regulatory publications, RSS feeds and relevant company or sector news. We are looking for someone with strong experience in Supabase, PostgreSQL, data engineering, API integration, scheduled ingestion, entity resolution, historical change detection and data provenance.

Mobile App Foundation Build: Flutter or React Native

I’m building a mobile platform for a specific industry vertical and need an experienced developer to build the foundational architecture it will run on. This is phase one of a larger, well-documented build, a full specification is available and will be shared with the successful candidate. The foundation covers: - User authentication and account creation - A multi-tenant data layer with strict isolation between accounts, enforced at the data layer, not just the interface - An offline-first sync skeleton: the app must work fully for data entry while offline, queuing actions locally and syncing once connectivity returns - An append-only event log as the core data model, every action recorded as an immutable event rather than overwriting existing records - A finance module (income, expenses, customers, suppliers, debtors, creditors, cash flow) and a staff/HR module (staff records, performance, salary), both built as reusable capabilities available to every part of the app, not tied to one feature - Two initial screens built on top of the above, to prove the foundation holds real functionality, not just plumbing This phase does not include: UI/UX design (a separate design pass is planned later), any operation-specific features beyond the two initial screens, or third-party integrations. Target platform: cross-platform mobile (Flutter or React Native, open to your recommendation with reasoning). Please quote your hourly rate and estimated hours for this scope specifically, rather than a fixed total, given some of this (particularly multi-tenancy and offline sync) needs to be scoped properly once you’ve reviewed the full specification. Prior experience with offline-first mobile apps and multi-tenant SaaS architecture is more important here than industry-specific experience.

Create a structured LinkedIn content plan. Write approximately 2 high-quality LinkedIn posts per week. Develop a consistent writing style and tone that sounds like me. Suggest strong hooks and angles for posts. Balance educational content, opinions, founder experiences and commercial insight.

There may also be opportunities later to help with: LinkedIn carousels Simple post graphics Case-study content Newsletter/article content Profile optimisation Content scheduling Comment / engagement strategy Writing style I am not looking for overly polished corporate marketing copy. The content should feel: Human Experienced Credible Conversational Practical Commercially aware Occasionally opinionated Easy to understand I want the content to demonstrate expertise without constantly selling.

Here are 7 trends you need to know.” The best content will come from real experiences, real projects, observations and strong points of view. Ideal freelancer You will ideally have experience working with: B2B founders Consultants Technology executives SaaS companies Data / AI companies Professional services firms MSPs or IT services companies Previous experience ghostwriting for founders or executives on LinkedIn is highly desirable.

I will provide a short voice note, call transcript or explanation of a topic. I would then like you to turn that into 2 different LinkedIn posts with different angles. The objective of the test is not just to assess writing quality. I want to see whether you can identify the interesting idea behind what I am saying and turn it into content that sounds natural and credible. Ongoing engagement If we work well together, I am looking for an ongoing relationship rather than a one-off project.
