Conversation designer, built on 10+ years of writing and research for regulated and consumer software. I find the knowledge buried in complex systems and give it a voice people can trust and act on.

ten years, in brief
Five roles across technical writing, AI content design, UX research, and enterprise documentation, each with the numbers it moved. Select a role to expand it.
A generator-and-reviewer conversation system for a GitHub pull-request documentation agent. A conservative grounding engine, designed under ISO/IEC 42001, ties generated claims to their source in the pull request, at 95% traceability; across two moderated sessions, human-in-the-loop governance cut manual corrections by 25% and time from trigger to publish by 30%, both small-n and directional. Built on five context-adaptive tone modes, seven conversation flows, and a three-tier delegation model that auto-applies above 0.85 confidence, suggests between 0.65 and 0.84, and hands to full review below.
A scripted guide in the corner of every page, designed end to end as an independent project. No model runs when a visitor asks, so each of its 139 intents answers with a reply I wrote in advance. It follows an act, confirm, hand off pattern, with pacing specified in milliseconds, and an automated suite checks readability, length and style before every deploy. The rules behind its voice are in the conversation style guide, and the build is in case 02.
In-product content and structured DITA documentation for Clinical One and Empirica, two regulated clinical-trial platforms whose users include the FDA and Merck. Every action in Clinical One is audited, and the content ships under ISO 13485 and ISO 82079. On the content I redesigned, progressive disclosure and in-app guidance raised task success by 40% and cut support tickets by 30%; clearer microcopy lowered interaction cost by 50%; a single-source DITA pipeline reduced documentation bugs by 70% across 40+ publications at 95% reuse consistency. Core contributor to the Redwood design system, recognised with the 2024 Indigo Design Gold Award.
Cross-border user research for an Interreg programme worth €201M: 100+ stakeholders, a baseline covering 12.4M citizens, and 255 coded findings that each traced back to source. A national needs study of Romania’s public administration, an institution serving 19M+ citizens, drew 1,782 open-question responses and shaped a training redesign, tested for usability before and after.
End-to-end editorial process across 400+ scientific assets, with turnaround cut by 20%. Single-source XML (JATS), convert-once-publish-many across HTML, PDF, and XML, and terminology standardised across every channel.
Onboarding and microcopy for consumer products, including a construction platform that reached 2 million people and lowered interaction cost by 50%. Copy grounded in 60 interviews across three rounds, run with the Berlin research team, and validated three times over, by card sort, A/B test, and an observational study. 2017 Innovation Award.

My hands are on the design layer: flows, intent maps, prompts, and the QA that keeps an agent grounded. Visual and UI design sit with the product designers I work beside, in Figma. I do not ship production application code. Platform consoles like Dialogflow and Lex have not been my daily tools, and contact-centre operations are outside my track.
