Product leadership for platform, API, and connected systems - turning system capability into buildable products. I work with growing businesses and operational teams, turning ambiguous platform or workflow challenges into clear scope, UX flows, and buildable direction. Often in API-heavy or integration-heavy products where the challenge is making systems usable across UI, integrations, and teams. Much of this work involves tracking an asset, approval, or item through a lifecycle - making operational processes visible at each stage. I'm typically brought in when a small core team is already in place, but key product decisions aren't explicit. Scope shifts, priorities blur, and delivery slows because intent isn't clearly defined. I close that gap by making product decisions deliberate and buildable - so teams stop guessing and start shipping. Recent work: NFC-connected mobile app: ideation → MVP scope → pilot launch Health IoT SDK/API portal: aligned hardware, firmware, and software delivery Sentiment-data API: integration UX and developer-facing flows Construction IoT platform: discovery through delivery Push notifications and API microservice: discovery → launch → scale in 22+ countries What I do – Define MVP scope (and what not to build) – Map UX flows and edge cases – Create clear, developer-ready requirements – Set up lightweight delivery systems (Notion, Linear, GitHub) – Align hardware, firmware, and software tracks Best fit – Early-stage founders building real products (pre-seed to Series A) – Teams building connected devices, wearables, or API-led platforms – Technical founders stretched thin on product decisions I work with a small number of teams at a time, building durable product foundations from discovery through delivery. Engagements typically run over multiple months, supporting both initial delivery and product expansion.
