Hands-on experience with microcontrollers (ESP32, Arduino), C/C++, MQTT, robotics kinematics & motion control, hardware sensor integration, and real-time telemetry streaming into cloud backends.

AI & Data Engineering

Building intelligent workflows, LLM agents, automated data extraction pipelines, and analytics infrastructure that convert data into actionable outcomes.

Product Leadership & UI Craft

As CTO of DreamGen Labs and OpenCorex founder, I connect user experience and technical depth, delivering shippable products with clean design and steady execution.

IoT specialization

A clear strength in connected-device platforms

IoT is not just a line item in my stack. I work across embedded hardware, communication protocols, device-facing applications, and the cloud-supported management layer around them.

Embedded and device layer

Hands-on work with Arduino, ESP32, sensor integration, and device-oriented application logic that connects hardware behavior to software workflows.

Real-time communication

MQTT-based communication patterns, connected-device messaging, secure configuration flows, and visibility across active device states.

Management experiences

React Native mobile apps and React-based admin portals for monitoring, configuration, alerting, and device management at the application level.

Cloud-backed reliability

AWS-backed support for reliable device operations, scalable backend services, and production-minded rollout for real-world connected systems.

Open-source specialization

Open source is part of the engineering identity

I treat open-source work as serious engineering: reusable systems, contributor-ready structure, maintainable architecture, and tools with long-term value.

OpenCorex leadership

Founded and lead OpenCorex as an open-source organization focused on practical developer tools, clean architecture, and community-driven engineering.

Reusable engineering work

I enjoy building frameworks, packages, and project foundations that other developers can adopt, extend, and maintain with confidence.

Contributor-friendly structure

I value documentation clarity, understandable architecture, and implementation choices that make collaboration easier for future contributors.

Long-term maintainability

My open-source approach is shaped by release discipline, readable code, scalable structure, and practical decisions that keep projects healthy over time.

Applied systems

Domains and systems I have worked across.

This is the practical footprint behind the profile: IoT, backend tooling, ERP-style operations software, university systems, and open-source engineering work.

Connected IoT Fleet Telematics & Monitoring

Cross-platform mobile and web consoles delivering real-time telemetry, cryptographic device authentication, and cloud fleet synchronization on AWS.

Enterprise Backend Framework & Tooling

Engineered modular TypeScript architectural frameworks featuring declarative decorators, dependency injection, CLI engines, and automated SSR metadata handling.

Industrial & Marine Enterprise ERP

Mission-critical operations platform automating multi-currency invoicing, crew payroll, role-based access control (RBAC), and real-time operational notifications.

Academic & Community Distributed Platforms

High-concurrency community web portals, clinical tele-appointment systems, and supply-chain logistics engines built for resilience and ease of scale.
