Founder and consultant building software where data, sync, privacy, integrations, and constrained runtimes get difficult.
local-first software / embedded applications / hard product work
I build and rescue software where the hard parts are data, sync, privacy, integrations, constrained runtimes, and keeping the thing alive after the first demo.
$ ls hard-parts
Selected work where the interesting part was not just shipping screens, but making data, devices, workflows, integrations, and operational edges hold together.
Privacy-first time tracking product
Privacy-first team time tracking for sensitive work, with desktop capture, portal review, encrypted task content, hosted sync, and self-hosted deployment paths.
Role: Founder and product builder, working full-time across product definition, local-first architecture, privacy model, sync/storage design, implementation, and operations.
Open-source local-first database infrastructure
Open-source Dart package for CRDT-aware Drift databases, extracted from Trackself infrastructure and generalized for other Flutter/Dart applications.
Role: Authored the package as Trackself infrastructure, then put in the extra work to make it general and useful outside the product.
Embedded display product systems
Long-running E Ink product work with Visionect, from Wemar Nautipad and Geoffrey to later Joan and CMS display-unit applications.
Role: Early application engineer and recurring consultant across E Ink product applications, embedded display runtimes, device content, protocol integrations, and product-platform continuity.
Enterprise document management systems
Lotus Domino consulting for internal HETA enterprise document management systems.
Role: Worked on and maintained internal enterprise document management systems where reliability, workflow continuity, and business operations mattered more than novelty.
IoT automation platform
IoT and smart-device automation platform with integrations, a rule engine, and a user interface for controlling devices from one place.
Role: Joined an in-flight beta effort, shipped Stripe integration across frontend and backend, and built the beta launch marketing website.
Offline-first messaging prototype
Web application packaged as a desktop app, expected to run online and offline with email, instant messaging, and proprietary API synchronization.
Role: Architected and implemented the browser-independent data layer, including metadata, text-message, and binary-object synchronization.
Competitive intelligence SaaS
Competitive intelligence application for monitoring complete market landscapes, gap analysis, and share-of-voice trend reporting.
Role: Built frontend features and improved the application architecture by introducing Marionette, reducing callback-heavy flows, and adding gettext localization infrastructure.
Fashion house website
Website for a haute couture fashion house, launched in summer 2014.
Role: Implemented the single-page application portion and integrated a WordPress CMS with a Marionette-based frontend.
Removal marketplace
Marketplace for removal companies and consumers seeking removal services.
Role: Improved fidelity and UX for the Backbone-based booking flow, introduced better Backbone practices, and refactored key UI areas.
Web application
Online marketplace with a clean workflow, strong mobile support, and marketplace payments.
Role: Helped with backend development, SDLC, i18n/l10n know-how, REST API services, and PayPal Adaptive Payments integration.
$ cat about.md
I am a hands-on software engineer and product builder focused on systems that have to survive real use: local-first desktop apps, sync and storage infrastructure, embedded display applications, enterprise workflows, and data-heavy product interfaces.
My best work usually sits where product judgment and implementation details meet. I care about clear domain models, operational edges, privacy boundaries, and code that remains understandable after the first release.
