For teams who need a senior dataviz engineer
Dataviz Engineering
Production-ready dataviz, built to last
- You get a production feature that passes accessibility and performance review
- Your in-house team can extend and maintain the code after handover
- You avoid the eighteen-month rewrite that follows most generalist-built dataviz
Who this is for
Your frontend team can ship UI. They cannot, or should not, ship complex dataviz. The skills do not overlap as much as recruiters think they do — D3, visual encoding, accessible chart semantics, and interaction patterns all need dedicated practice.
Typical scenarios:
- A Series A–C SaaS company shipping an analytics view, explorer, or chart-heavy dashboard and needing senior dataviz capacity for 6–12 weeks
- An ML or AI product company building model output, attribution, or uncertainty views that their users need to trust
- A design-system team that wants a chart component library built properly once, rather than grown accidentally over years
- A research group or NGO with a publication or campaign deadline and a need for visualisation that clears editorial-standard review
If you are reaching for Recharts and hitting its limits, or considering a D3 build but nobody on your team has shipped one, this is the right service.
What happens, step by step
Discovery or handover
- Either you book a separate Discovery & Scoping Workshop first, or you provide an existing brief and we start from there.
The engagement starts with an agreed scope, a fixed price, and a written definition of done.
Design and architecture
- I produce visual designs and a technical architecture covering data flow, component structure, and state management.
- Both get reviewed with your team before any feature code is written.
Your engineering leads sign off on the approach before any substantial code is committed.
Build in sprints
- Work ships to a staging environment in weekly increments.
- You see something real every week. No month-long silence, no big reveal.
Your team can check progress at any time. Nobody is guessing whether things are on track.
Accessibility, testing, and documentation
- WCAG 2.2 accessibility review and performance check on real devices.
- Unit tests on chart components and written documentation for extension.
Your in-house team can extend this code without calling me.
Handover walkthrough
- A 90-minute walkthrough with your engineering team covering architecture, decisions, and limitations.
Your team leaves knowing why the code is the shape it is, not just what it does.
Typical engagement
A clickable prototype of a single chart, explorer, or interaction, built to validate a concept. Observable, Svelte, or plain HTML, wired to your real or sample data.
What's Included:
- One chart or one explorer scope
- Real or sample data integration
- Clickable interaction model
- Best for: proving concept to investors/stakeholders
