What we deliver

01

IoT and Telematics

Server-side infrastructure for connected vehicles and IoT devices. Designed and load-tested telemetry platforms handling 100,000+ devices transmitting in real time. Shipped on T-Mobile networks in the US and Czech Republic, reaching 100,000 connected vehicles. Deep experience with MQTT, Azure Event Hubs, and distributed telemetry pipelines from ingestion through analysis.

02

AI Enablement

Prototyping and integrating AI capabilities into real products. Built MCP-based agent interfaces over live telemetry data, enabling conversational vehicle commands, state-of-health queries, and automated customer summaries. Evaluated local and cloud model approaches, embedding-based retrieval, and workflow prototyping for production readiness.

03

Architecture and Design

Solution and enterprise architecture across healthcare, automotive, e-commerce, and digital print. From approved $2M re-architecture programs to startup-grade SaaS platforms, we define technical direction that balances scale, cost, and business goals. SOLID, DDD, CQRS, and event sourcing applied where they earn their complexity.

04

Platform Modernization

Reduced order and accounting data flow from roughly 3 days to a few seconds for 400 clinics while maintaining 99.99% uptime. Standardized onboarding of thousands of containerized applications into Kubernetes, cutting delivery timelines by 6 to 8 months. Shipped 15 releases across three product editions, raising customer satisfaction from 3.0 to 4.7 out of 5.

05

Delivery and Leadership

Greenfield to production, with the discipline to get there. Scaled teams from 1 to 7 and guided groups of 3 to 20 through release cadence, engineering standards, and SaaS architecture direction. Hands-on through every stage: technical design, implementation, deployment, and operational monitoring.

06

Cross-Platform and Connected Clients

Cross-platform SDKs and applications for Mac, Linux, Android, iOS, and Windows. Delivered connected-car APIs with early external adoption. Built customer-facing mobile applications with Xamarin for four platforms and contributed directly to a .NET MAUI client application for connected vehicles.

07

Executive Leadership

VP-level technical leadership with a hands-on style. Built SaaS centers of excellence, established architectural governance, and directed engineering teams of up to 25. We lead from the keyboard, not just the whiteboard. Experience presenting to boards, negotiating build-vs-buy trade-offs with executive stakeholders, and hiring teams from scratch through scale. Microsoft MVP for 6 years and founding ASPInsiders member.

08

Cloud-Native Infrastructure

Kubernetes-first platform architecture, Azure and AWS ready. Designed next-generation systems targeting 1,000,000 connected devices. Standardized onboarding of thousands of Docker images into Kubernetes deployment pipelines, cutting delivery timelines by 6 to 8 months. Helm, Docker, Cosmos DB, Service Fabric, and the operational patterns that keep distributed systems running.

09

Observability and Reliability

Instrumenting production systems so they become legible. OpenTelemetry, InfluxDB, and Grafana dashboards that turn telemetry into decisions. Designed and load-tested platforms verified at 100,000+ concurrent devices. 99.99% uptime is not a target; it is a delivered outcome.
