Full-Stack & AI Product Engineer

Bring me the idea. I'll help you ship the product.

I'm Harjot, a full-stack engineer and AI engineer. If you have a Figma, a rough brief, or a half-built product, I'll help turn it into something real, live, and maintainable. I built Moonshift, a multi-agent app builder that served 1,200+ users, so I know the gap between a demo and a product people can actually use.

What are you trying to ship?

The best fit is a real product problem with a decision-maker, a useful first milestone, and a willingness to keep scope honest.

You have an ideaYou need a small, useful first version and a technical partner who can help decide what not to build yet.
You have a productYou need an AI feature, integration, reliability pass, or another pair of hands to move the roadmap forward.
Your codebase is stuckThe prototype works in a demo but is slow, fragile, insecure, or difficult to take to production.

Ways I can help

Every engagement starts with a written scope. The right shape and price depend on the product, the deadline, and what already exists.

Idea to live MVP

For founders without a technical co-founder

Scope the smallest useful product, build the core experience, connect the backend, and deploy it with a handover you can own.

AI product sprint

For teams adding AI to an existing product

Turn an LLM, agent, RAG, or automation idea into a working feature with sensible evaluation, observability, and cost decisions.

Product or codebase rescue

For half-built or AI-generated products

Find the highest-risk problems, make the next fixes concrete, and create a path from fragile prototype to shippable product.

Diagnostic first · implementation quoted separately

Fractional product engineering

For small teams that need ownership

Take responsibility for a product area, ship continuously, and give a founder or product team dependable technical momentum without adding a full-time hire immediately.

A straightforward process

Understand the problemA short call or written brief clarifies the user, desired outcome, constraints, urgency, and what success means.
Write the smallest useful scopeYou receive a clear proposal with deliverables, exclusions, milestones, dependencies, and a fixed price or monthly arrangement.
Build in visible incrementsWork is shipped in small steps with a written update each week and decisions recorded when scope changes.
Launch and hand overThe product is deployed to your infrastructure, with documentation, a walkthrough, and an agreed support window.
Decide what comes nextWe close the loop with the next product priorities, a maintenance plan, or a clean handoff to your team.

Before we start

How does remote collaboration work?

I work remotely from New Delhi (IST). We agree on overlap for important decisions, use written updates for the rest, and keep dependencies visible so timezone differences do not become a surprise.

How are scope and payments handled?

The proposal defines what is included, what is not, milestones, payment timing, ownership, and support. Changes are quoted separately instead of being hidden in an open-ended invoice.

What if I am not sure what to build?

That is fine. Share the idea, the customer, and what you have tried. I can help turn it into a smaller first milestone before we commit to a build.

Are you available for contract work and full-time roles?

Yes. I take contract and freelance engagements as a full-stack engineer and AI engineer, and I am open to full-time roles. Client work starts with a written scope on this page. For full-time hiring, email me@harjotrana.com or book a call; the resume has the fuller employment history.

Tell me what you are building.

A few useful details are enough to start: the product, the current stage, the outcome you want, and when it matters. I will reply with a practical next step within one business day.
