Product engineer shipping JS features inside real products.

I build the TypeScript layer that makes products do the thing — Webflow Components, Finsweet Attributes, generators, integrations, interfaces that hold up under real users. Seven years in, the last three at Finsweet.

Policy Generator, Consentpro CMP

Webflow users need GDPR-grade privacy policies and cookie declarations without a lawyer or a developer. I developed the feature that generates them — jurisdiction-aware, scanner-fed, and editable inside the site they already have.

TypeScript Svelte Webflow API Cloudflare Workers LLM assist
Consentpro Policy Generator: Privacy Rights master document covering GDPR, CCPA/CPRA, and US state laws
CON · constraints
Accurate per jurisdiction and locale. When the scan or vendors change, prompt for an update instead of silently rewriting. Reviewable by a marketer in the CMP — no CMS, no developer, no generic content.
DEC · decisions
Static templates with logic baked in — variable hydration, conditional sections, data loops — so one template set covers regimes and locales instead of a document per combination. Data lives on Cloudflare; published copy only moves when the customer accepts an update.
IMP · implementation
Svelte wizard in the CMP dashboard. TypeScript template engine on Cloudflare Workers, with all policy data synced on the edge. Change detection raises the update prompt; the same templates render each locale. LLM assist is confined to phrasing — never to the legal structure.
OUT · outcome
Compliance became a setup step rather than a project. Customers generate, review, and publish in their locales. The same template work then updated Finsweet and Consentpro’s documents.

Sugarologie Cakeculator: pan, flavor, cake type, servings, and frosting inputs through the recipe logic hub to a calculated vanilla bean cake recipe

The Cakeculator

A recipe engine dressed as a calculator: pick cake type, pan geometry, frosting and filling, and it rescales every ingredient, bake time and yield. The hard part was never the UI — it was the ratio model behind it and keeping it correct across pan volumes.

Webflow Product Engineer

Owned the Policy Generator in Consentpro CMP, then the legal compliance review that updated Finsweet and Consentpro policy documents. Designed and maintained Attributes and Components systems that let non-coders build CMS filtering, sliders, tabs and sortable content. Modularised the component library — reusable templates cut front-end build time by 20% — and continued fixing components bugs reducing clients churn ratio.
