Explained properly.

The diagrams are only the surface. These case studies show the architecture, data paths, production concerns, and ownership behind each build.

Remote Pulse project illustration: telemetry moves from ingestion through services to a live dashboard.

01 — Distributed platformArchitecture + full-stack build

Remote Pulse System

A production-minded telemetry platform that moves live data from ingestion to a browser dashboard. I owned the service design, processing pipeline, interface, observability, and local orchestration.

System design

.NET Aspire coordinates the API, workers, persistence, and frontend with explicit service boundaries.

Data path

gRPC ingestion feeds background processing; SignalR streams updates into a Blazor WebAssembly dashboard.

Production readiness

OpenTelemetry, structured logging, health checks, cancellation-aware workers, PostgreSQL, and SQLite.

02 — Full-stack commerceProduct + platform ownership

Northstar Market

A complete commerce product spanning the customer experience, operational workflows, API, and data model. The work demonstrates product thinking alongside full-stack implementation.

Product surface

Catalog browsing, favorites, cart, checkout, order history, and the admin workflows behind them.

Application design

A typed React client connects to a Node and Express API backed by Sequelize-managed persistence.

Engineering ownership

Frontend and backend structure, API contracts, state and data flows, testing, and deployment-ready setup.

React / TypeScript / Vite / Node.js / Express / Sequelize

Review the product and source

Conceptual ERP dashboard showing orders, POS activity, tables, kitchen workflow, delivery tracking, payments, and reporting.

Private project

03 — ERP platformPrivate product delivery

ERP System (Private project)

A multi-tenant ERP system for restaurant operations, bringing POS sessions, order lifecycle, tables, stations, kitchen workflows, delivery coordination, cash control, and reporting into one operational platform.

Operational scope

POS sessions, cash and card settlement, table and station management, order workflows, delivery operations, and daily reporting.

Backend design

Strict server-side validation, DTO-driven APIs, multi-tenant boundaries, concurrency handling, idempotency, and dependable business rules.

Reporting

Operational reports covering orders, payments, items, tables, drivers, user settlements, and detailed cash drops to safe.

Ringo PBX / CRM

Senior backend engineering for a communications platform where APIs, messaging, payments, and live operations meet.

Designed and extended .NET services for lead management and operational CRM workflows.
Built Twilio messaging and webhook integrations plus Stripe payment flows.
Supported API contracts, production issues, and AI automation across roughly 100 client environments.

The longer version — my CV

My background is in .NET. My work has taken me well beyond the backend.

I started building business applications in 2014. Since then, I’ve worked on enterprise systems, led development teams, and built products that connect APIs, real-time data, and user interfaces.

These days, I move between architecture and implementation: a React checkout, a distributed .NET service, or a voice agent connected to a business workflow. I stay involved through testing, deployment setup, and production support.

I care about what happens after release: how a system is monitored, how it fails, and how the next developer will work on it.
