This is a part-time, remote, contract role for a Freelance Web Developer. You will build and maintain client websites in Webflow and WordPress, including full site builds, service and industry pages, landing pages, case study templates, and CMS work, supporting our clients' goals across multiple accounts. You will turn designs into responsive, fast-loading pages, wire up integrations and tracking, and collaborate with our creative and marketing teams on builds that connect to real campaign goals. This is a largely async role. You will mostly work on your own schedule, so we want someone serious and capable who shows up reliably, manages their own work, and brings a strong point of view on what makes a site fast, clean, and built to last. We care about work that performs in the real world, not builds that look fine in the preview and fall apart on a phone. This is also not a drag-and-drop, template-and-pray role. We expect you to use AI fluently as a tool, but the build has to be solid, the code clean, and the structure intentional. If your sites are bloated, slow, or held together with workarounds you can't explain, this is not the fit **What you'll do** - Build and maintain Webflow and WordPress sites that are responsive, fast, and structured properly, from full builds to landing pages, service pages, and CMS work. - Turn Figma designs into pixel-accurate, mobile-first pages that look as good on a phone as they do on desktop. - Wire up integrations and tracking, including HubSpot forms, GA4, and Google Tag Manager, so every site captures and measures what it should. - Manage builds across several client accounts at once, switching platform, context, and brand cleanly between them. - Handle the technical housekeeping that keeps a site healthy, including page speed, accessibility, schema, and clean URL structure. - Drop into custom HTML, CSS, and light JavaScript, plus PHP on the WordPress side, when the platform alone won't get it done, and hit deadlines without hand-holding.

This project proposes a Terminal-Bench task focused on financial operations and spreadsheet automation rather than traditional software engineering. The agent is provided with a collection of Excel workbooks containing transaction records, account summaries, and reconciliation reports that contain multiple inconsistencies introduced during data processing. The objective is to identify and repair discrepancies between transaction-level data and account-level summaries using command-line tools and available spreadsheet-processing libraries. The agent must analyze workbook contents, detect missing or duplicated entries, correct formula errors, update derived calculations, and ensure that final balances match across all reports. The task is designed to reflect realistic accounting and finance workflows that organizations routinely perform. Success is verified programmatically through independent tests that validate balance consistency, formula correctness, reconciliation accuracy, and preservation of non-target workbook content. Unlike common coding benchmarks, this task emphasizes data integrity, spreadsheet manipulation, financial reasoning, and careful handling of structured business documents. The challenge requires the agent to inspect existing files, understand relationships between multiple worksheets, apply targeted corrections, and produce a fully reconciled set of outputs without modifying verification artifacts. The environment is fully self-contained and offline, with all required datasets included inside the task package. Automated tests verify that reconciliation rules are satisfied while ensuring that agents cannot bypass validation through hardcoded outputs or direct modification of test files.
