Services
I work with teams on existing IoT and connected systems — the kind where devices are already deployed, data is already flowing, and the problems are specific to your architecture.
Most engagements start as focused technical work and expand as complexity surfaces. I operate across the full stack: PCB-level constraints through cloud infrastructure.
Architecture Review
Project-based
Deep review of your IoT or embedded system architecture. I look at device firmware structure, network topology, data ingestion pipelines, and the boundaries where components interact. You get a written report with specific recommendations — not a deck of generalities.
IoT System Integration
Project-based
Multi-network device deployments, protocol bridging (MQTT, CoAP, LoRaWAN, LTE-M), cloud ingestion pipelines, and device lifecycle management. Particularly experienced with heterogeneous fleets where no two device types behave the same.
Production Debugging & Optimization
Retainer or project-based
When something is broken in production and nobody can figure out why. Field-deployed devices dropping data, ingestion pipelines silently losing events, firmware crashes that only happen under load. I find the root cause and fix it.
Embedded Firmware Development
Project-based
Custom firmware for STM32, ESP32, and similar MCUs. Sensor integration, communication stacks, power management, OTA update systems. I write firmware that survives deployment — not just firmware that compiles.
Selected Work
Turnkey IoT connectivity for industrial and utility clients in Peru. Full vertical: device provisioning, multi-network management (LoRaWAN, LTE-M, satellite), cloud data platform, and customer dashboards.
Hardware product line (DataEdge) and cloud platform (DataOS) for industrial monitoring. PCB design through Kubernetes deployment. Real-time data ingestion from heterogeneous sensor fleets.
Compliance-grade appointment and billing platform with full audit trails. Multi-tenant architecture handling sensitive patient data under strict regulatory requirements.
