Remarks

Nine years shipping products for banks, agencies, and small teams. Most of that time has been in financial services: pension and fiduciary tools, credit-risk analytics used by Revolut, Izola Bank, and BNF Bank, and an agency finance platform covering cashflow, KPIs, and live accounting sync. I lead frontend, testing, and delivery on small teams, and I pick up backend, integrations, and DevOps when that is what the work needs. Graphic design and UX background. I mentor when I can.

Exposures

  1. Antler Digital

    Lead Software Engineer

    Dec 2022 – PresentLondon, United Kingdom (remote)

    Startup studio. Team of 3–4. I own frontend, testing, and a large share of delivery across client and internal products.

    1. Common Thread

      2026

      Finance operating system for agencies. Turns project, invoice, and accounting data into cashflow, runway, and allocation views.

      • Built the product surface for cashflow forecasting, KPI dashboards, invoicing waterfalls, pipeline, operating expenses, and a weekly resource planner.
      • Shipped a read-only Xero sync (invoices, payments, reports, tax obligations) and a provider-neutral trunk so QuickBooks Online could follow the same ingest path.
      • Added scenario forecasting, FY-aware period controls, P&L workbook export, and an admin app for organisation onboarding.
      • Stack: Next.js, TypeScript, Drizzle, PostgreSQL/Neon, Bun, Xero, QuickBooks.

    2. Wiserfunding

      2023 – Present

      Credit-risk and portfolio analytics for lenders and investors. Clients include Revolut, Izola Bank, and BNF Bank. Lead frontend engineer for 3+ years.

      • Built the home dashboard as a widget board: sector risk heatmap, risk profile over time, macro environment, and recent assessments, with BFF caching for clustered reports.
      • Developed financial report and portfolio visualisations: choropleth maps, Gantt charts, packed bubbles, distribution charts, and AG Grid Enterprise views for comparison, custom charting, and export.
      • Shipped document intake for CSV/Excel and OCR/FX flows, including reporting-currency controls and WiserAI upload types.
      • Added Open Sanctions and legal-event signals to reports and portfolio alerts, plus NUTS regional concentration drill-down.
      • Built a multi-environment, multi-role test suite (Playwright, React Testing Library, Jest). Rewrote about 75% of the suite for Bun (about 6x faster than Jest) and a Playwright ID selector used by the backend team.

    3. PEW

      2024 – Present

      Global cocoa and chocolate brand. Multilingual marketing site plus a gated product portal and a separate assistant service.

      • Leading the move to Next.js App Router with route and SEO parity against the live Gatsby site.
      • Built the portal assistant as its own Mastra service: Contentful GraphQL tools, MCP with a write allowlist, DocumentDB RAG (Voyage embeddings), citation-domain rules, rate limits, and a 36-question golden-set eval in CI.
      • Designed and ran an AWS AgentCore POC behind the portal: CDK, Bedrock Claude and Nova, a private DocumentDB cluster, and an MCP gateway Lambda.
      • Added Payload CMS, browser-bound email OTP, domain-gated access, and approval onboarding for the portal.

    5. One Tribe

      2022 – Present

      Carbon marketplace and event-impact reporting. Marketplace, subscriptions, and a live events calculator used for stand, meal, and flight emissions.

      • Rebuilt the marketplace in about 3 months: 7 UI libraries down to Tailwind, one state system (Recoil), SSR pages, and Auth.js.
      • Replaced a loss-making PayPal setup with Stripe. Peak volume over £100k/month, no customer downtime.
      • Built the BigCommerce client portal (Firebase functions, later Xata) and a Next.js admin so non-Stripe specialists could manage merchants and subscriptions.
      • Helped migrate Firebase to Xata with 1 day of downtime, no revenue loss, and only minor UI bugs.
      • Built the events carbon calculator (stands, meals, flights, PDF submissions) and, in 2026, a Bun monorepo for platform, impact pages, admin, custom stats, and carbon-report email sharing.
      • Added Bun unit tests and Playwright E2E in CI (CircleCI, then GitHub Actions). Financially sensitive code written with TDD.

      • Added sold-quantity tracking, early-setup add-ons, Google Calendar receipts, and Turnstile-protected forms.
      • Shipped Capital Antiques Market as a second branded site on the same MongoDB codebase, with its own emails, settings, seed data, and admin.
