Experience

Blakthumb

A SPA with GraphQL back end is intended for managing processes on a farm, typically a vertical indoor farm. Technology stack includes Vue.js, TypeScript, Apollo GraphQL client and server, Babylon.js in-browser 3D visualization library, Web Speech API, and camera access for barcode and QR code scanning.

Web Application for M&A Due Diligence

A Vue 3, TypeScript web application with TypeScript back end and GraphQL API. I helped the client design, shape, and optimize the solution and then led its implementation. The MVP attracted considerable interest from the top players in the industry.

WithYouWithMe Potential Web App

https://potential.withyouwithme.com/
An HTML5 web and PWA application that I initially developed solo as a POC and evolved into the company's flagship over time. I continued to oversee the development of and contribute in various areas, first as a lead developer, then head of engineering, and CTO.

Automated Packaging Design Application Focusing on Sustainability

http://my.unpac.app
An AI-assisted application for designing packaging to user's requirements. Users enter their requirements into a smart form. Those initial requirements then prompt the AI to converse with the user to clarify their needs and discuss designs. In the end, the AI generates solutions that meet user requirements.

Capability.co | User and Admin Customer Portals

https://portal.capability.co
I developed a Kubernetes-hosted, service-based, highly portable cloud-native application with zero external SaaS dependencies. It featured a federated GraphQL schema and leveraged multiple CNCF open-source components: Keycloak identity server, RabbitMQ, Redis, PostgreSQL, Apache Superset for data visualization, Trino for distributed querying, n8n for no-code workflow automation, and Tilt with Kind for local development in Kubernetes.
