Full-stack AI product engineer

I Build Intelligent Products that turn Complexity into Clarity.

I build AI-enabled products from the backend out—shaping services, data flows, and AI integrations, then carrying them through to the frontend and production.

The short version

AI-aware backend engineering, full-stack delivery, and products built to work in the real world.

I work across AI integrations, APIs, services, data models, infrastructure, and React/TypeScript interfaces—owning the path from system architecture to product delivery.

Selected work

A few things I have built and explored.

A mix of shipped AI capabilities, full-stack systems, personal products, and clearly labeled experiments.

AI PRODUCT DEVELOPMENT · 01PRODUCT WORK

AI capabilities, built end to end.

At Userflow x Beamer, I worked across AI integrations, Java/Spring services, React/TypeScript, data, and release workflows to bring customer-facing capabilities from idea to production.

PERSONAL PRODUCTClicknrec

Where intelligence meets the editing experience.

Clicknrec explores how voice, video, transcription, capture, and AI-assisted workflows can work together in one product.

  • Explored how AI can support creative work without hiding the underlying editing experience.
  • Built across interface, backend, media processing, and extension surfaces as a full-stack product experiment.

Exploring the future of AI products.

A proof-of-concept exploration into how agents, context, and tools can help people work with software.

Proof of concept
AI PRODUCT EXPLORATIONPROTOTYPE

Making AI systems easier to understand and use.

I explored agentic product patterns, retrieval, orchestration, tool use, and human review as building blocks for useful software, while keeping the work clearly in the prototype category.

  • Explored how context and tools can connect an AI system to a product workflow.
  • Looked at how human review and clear system boundaries shape trustworthy AI experiences.

OpenPDF Tools: a small, focused browser product.

A personal utility with a simple promise: useful PDF work, performed locally in the browser.

Keep the product promise simple.

OpenPDF Tools explores direct interaction, local processing, and privacy-first product design in a compact browser experience.

  • Designed around a focused workflow with feedback close to the user’s action.
  • Kept the product lightweight and local so files remain on the user’s device.

I care about the whole path: what the system needs, how the intelligence is integrated, how the data moves, and how the product behaves for the person using it.

Across SaaS, AI-enabled products, and industrial applications, I’ve worked across backend services, application and data modeling, AI integrations, frontend delivery, and infrastructure. Today, that means Java/Spring and Node.js backend work paired with React/TypeScript, modern infrastructure, and practical AI implementation.

01
Make AI useful.

Start from the problem, then choose the smallest reliable AI loop that helps.

02
Design clear system boundaries.

Keep model behavior, application logic, data, and human review understandable and controllable.

03
Ship the whole system.

Good product work connects interface, backend, data, infrastructure, and the details in between.
