Forward Deployed Engineer

I build productsfrom messy ideasto working systems.

Full-stack · AI · Automation — turning complicated workflows into software people can actually use.

I don't just write code.
I figure out what the code should do.

I turn messy business workflows into RAG and agent prototypes, then ship them as production full-stack systems.

How the systems actually fit together.

Hover or select a node. This is the shape of the stacks I ship — product UI, APIs, data, and AI automation in one loop.

Talks to

Thinking

The problems I like solving.

Not skill percentages. The kinds of systems I want to own end to end.

Complex product workflows

Multi-role apps, admin systems, permissions, and state-heavy operational flows.

AI automation

Agents, RAG, MCP tool calling, prompt systems, and intelligent tooling that ships.

Backend architecture

API design, data models, integrations, and the failure modes between them.

Performance

Cutting redundant requests, frontend drag, and bottlenecks that waste operator time.

Multi-tenancy

Isolation, permissions, organization boundaries, and privacy that holds under load.

Prototype → production

Taking a working AI demo and hardening it into something operations can trust.

Fast interfaces

Not just pretty interfaces.

Predictable systems

Not just working happy paths.

Secure defaults

Not security as an afterthought.

Simple architecture

Until complexity is actually justified.

About

Yuvraj Singh

I like taking complicated systems apart, understanding why they fail, and rebuilding them into something people can actually use.

I work across product, frontend, backend, automation, and infrastructure. The part I enjoy most isn't writing code — it's figuring out what the code should do.
