Featured Projects
Work I'm proud of
Analytics Dashboard
Comprehensive dashboard featuring fraud detection systems, ML model management interfaces, campaign management tools, and real-time analytics. Built with TypeScript and MUI DataGrid for performance-optimized data visualization.
TECHNOLOGIES
tapkanconsulting.com
Production Phoenix/LiveView application serving this consulting portfolio and contact pipeline, deployed on Fly.io with PostgreSQL. Includes an Nx/Axon-backed semantic project search built directly into the site.
TECHNOLOGIES
LocaliQ Advertising Reporting Platform
Owned the React/Redux dashboard layer of LocaliQ's multi-tenant advertising reporting platform, serving roughly 12,000 advertisers across North America, Europe, Latin America, and Asia-Pacific. Worked across three successive backends for the same product - the original Rails application, an Elixir/Phoenix OTP umbrella, and the current Node/Fastify service. Delivered a multi-tenant benchmarking sandbox, multi-location reporting access control, and geofencing/walk-in attribution reporting, and cut typical dashboard response times from roughly five seconds to under one.
TECHNOLOGIES
Self hosted Legacy Stack Showcase
ASP.NET MVC with Angular 10 framework.
TECHNOLOGIES
Self-hosted IoT / Session / Strava Integration
Integration of IoT weather station data with Strava for fitness tracking and analysis.
TECHNOLOGIES
Real-time Collaboration App
Elixir/Phoenix application with LiveView for real-time data synchronization and presence tracking. Demonstrates fault-tolerant concurrent architecture.
TECHNOLOGIES
Personal Blog & Portfolio
Next.js-based blog with MDX support, custom photo gallery components, and responsive design. Documents travel experiences and technical musings with high-quality image galleries.
