Engineer | Research | GenAI | MLOps | Embedded Systems

I am an engineer focused on building complete systems.

Not isolated models.
Not standalone code.
Not one-off hardware prototypes.

I work across hardware, firmware, software, AI/ML, and infrastructure, and take ideas from concept to production with an emphasis on correctness, scalability, and long-term maintainability.

My foundation started at the lowest levels of systems: registers, signals, timing, and constraints.

Over time, that understanding expanded upward:

• from firmware to embedded systems
• from systems to software
• from software to machine learning
• and into production-grade AI systems

Today, my focus is on building systems that not only work,
but continue to operate reliably as complexity and scale increase.

• Machine Learning and AI model development
• Production ML using MLOps practices
• Backend system design and implementation
• Embedded systems and firmware development
• Technical leadership and team mentorship

I prioritize engineering fundamentals, clear abstractions, and system-level thinking.

My current work is centered on:

• Generative AI systems
• Production-grade backend architectures
• End-to-end ML systems
  (training → deployment → monitoring → iteration)

Models are experiments.
Systems are responsibilities.

I treat machine learning models as long-lived products, not notebooks.

• Experiment tracking and model lifecycle management
• Data, model, and code versioning
• CI/CD for ML workflows
• API-based model serving
• Monitoring, drift detection, and observability

The objective is consistent:
predictable behavior in unpredictable environments.

My embedded work spans:

• Arduino, ESP32, Raspberry Pi
• STM32 microcontrollers
• Register-level programming
• RTOS and Embedded Linux

I am particularly interested in systems where hardware, software, and intelligence intersect.

Engineering impact extends beyond code.

• Lead GenAI and Embedded Systems teams
• Mentor and train engineering students and professionals
• Active in the engineering community in Coimbatore, Tamil Nadu
• Develop structured learning roadmaps for hardware and software engineers

I value building environments where engineers grow in both skill and judgment.

• Maintain repositories with engineering roadmaps and reference implementations
• Contribute to and support open-source projects
• Emphasize clarity, reproducibility, and real-world applicability

If something helped me understand a system deeply,
I document it so others can build on it.

• End-to-end ownership
• Strong fundamentals
• Thoughtful mentorship
• Systems that work beyond demos

Good engineering is quiet.
It fails less, surprises less, and lasts longer.

📫 Open to collaboration and engineering discussions.
