Building the next generation of AI-driven mobile and web experiences.
For me, development isn't just about writing code it’s about velocity and impact. In today’s landscape, that means combining deep engineering expertise with the latest in AI to build products that are smarter, faster, and more intuitive than ever before.
I am a Full Stack Engineer specializing in React Native and AI-Native development. I don't just integrate APIs; I build "Agentic" systems that leverage LLMs for complex reasoning, multi-modal search, and personalized user experiences. By utilizing advanced AI tools (Cursor, Claude, and custom MCP servers), I deliver production-ready code significantly faster than traditional workflows.
Core Technical Arsenal:
- Mobile: Expert-level React Native (iOS/Android), Native modules (Swift/Kotlin), and Expo SDK 50+.
- AI & Intelligence: Deep experience with OpenAI, Claude (Anthropic), and LangChain. Specialist in RAG (Retrieval-Augmented Generation), vector databases (pgvector/Pinecone), and local LLM optimization.
- Full Stack & Cloud: Node.js, Next.js, and Python backends. Expert in AWS/Azure/GCP and automated CI/CD pipelines.
Legacy Strength: Years of experience in Swift, Objective-C, Kotlin, and Java for high-performance native bridges.
Since 2018, I’ve taken projects from a blank page to thousands of active users. I take full ownership of the product lifecycle from architecting scalable backends to polishing the "premium" feel of the UI.
What I bring to your project:
- AI Strategy: I’ll help you figure out where AI adds real value and where it’s just noise.
- Scalable Engineering: Code that doesn’t just work today, but scales to a million users tomorrow.
- Transparency: No jargon. Just clear updates, honest timelines, and a focus on your ROI.
Outside of work, I love to travel, explore new places.
