About Me

I'm a Software Engineer with over 5 years of expertise in software development, specializing in UI design, programming, and troubleshooting. I thrive at the intersection of design and engineering — where great UX meets clean, scalable code.

Currently, I'm a Senior Frontend Engineer at Mida Technologies, leading the design and implementation of financial services applications. Previously, I built full-stack web3 and fintech products at Oobla, where I architected core banking applications and designed decentralized systems.

I'm a proven leader with a track record of successfully leading cross-functional teams. A quick learner and collaborative problem-solver, known for providing excellent engineering services in remote and hybrid environments.

Beyond work, I explore micro-frontend architectures, maintain open-source component libraries, and study systems design & ML/AI to become a better engineer every day.

What Intrigues Me

Artificial Intelligence

From neural networks to real-world inference — I'm fascinated by how machines learn, reason, and increasingly augment human capability.

Agentic Workflows

Autonomous agent orchestration, tool-use chains, and multi-step reasoning — the future of software is agents that plan, act, and iterate on their own.

Large Language Models

Training, fine-tuning, RAG pipelines, and prompt engineering — I explore how LLMs can be shaped into domain-specific powerhouses.

Cyber & Network Security

Threat modeling, encryption, zero-trust architectures — building systems that are not just functional but resilient against adversarial actors.
