Full-stack AI product engineer

Make complex product feel clear.

I build web products that bring together thoughtful product UX, full-stack engineering, and practical AI.

The short version

Full-stack delivery, front-end craft, and AI that earns its place in the product.

My work sits at the intersection of product engineering and product judgment: shaping the interface, the backend, the data model, and the human workflow around an intelligent feature.

Selected work

A few things I have built and explored.

A mix of product development, technical exploration, and small tools—described by the ideas they represent.

AI PRODUCT DEVELOPMENT · 01PRODUCT WORK

End-to-end AI product development.

At Userflow x Beamer, I used AI tools and full-stack engineering to help bring customer-facing ideas from exploration to production-ready product features.

AI-first media and creative workflows.

A personal product exploration into how capture, transcription, voice, video, and AI-assisted workflows can come together.

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.

PERSONAL PRODUCTOPENPDFTOOLS.SABARINATH.DEV

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 seam between engineering and judgment: what the user sees, what the system needs, and what the product should let a person decide.

Across SaaS, AI-enabled products, and industrial applications, I’ve worked across frontend, backend, data, and delivery. Today, that means React and TypeScript craft paired with Java/Spring depth, modern infrastructure, and practical AI implementation.

01
Make the model useful.

Start from the user’s job, then choose the smallest reliable AI loop that helps.

02
Keep the product legible.

New technology should feel understandable, responsive, and grounded in a real need.

03
Ship the whole system.

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