Available for work

I build AI features that survive real users.

And the products and websites around them. Nine years building software in-house, most recently leading engineering at VMock. Now independent, working with founders and teams who need it done properly.

Services

Usually two to four weeks, architecture through to a deployed feature.

Put an AI feature in front of real users

Teams whose AI feature has to answer to a real customer, an auditor, or both.

You have a feature that needs a model behind it, and a demo is not the same as a thing customers use. I build the agent and the parts that make it accountable: what it can see, which tool ran, where a person signs off.

  • Agent architecture and orchestration (LangGraph, LangChain)
  • Streaming interfaces over WebSockets
  • Tool and API integration
  • Evaluation, tracing and diagnostics (Langfuse)
  • FastAPI services and deployment
Usually two to three weeks, design through to launch.

Ship a site that loads fast and stays fast

Founders and small teams who want to stop ringing a developer to change a price.

A site you can change yourself, that loads fast on a phone in a regional town and scores 100 for accessibility because it was built that way, not audited afterwards.

  • Design and front-end build (Next.js, React, TypeScript)
  • Design systems and reusable components
  • Performance work — Core Web Vitals, bundle size, build times
  • Accessibility to WCAG AA
  • Deployment and CI
Usually a four-week module, scoped before it starts.

Turn a vague idea into a shipped scope

Teams who know the problem, have a date, and need one person accountable from the scoping to the handover.

Someone has to turn “we need something like this” into a thing that ships, and then still make sense to the next person who opens it. Usually that means deciding what not to build.

  • Requirement refinement and scoping
  • Configuration-driven architecture for multi-client products
  • Cross-functional delivery with design and QA
  • Technical leadership and code review
  • Launch and handover
Usually a one-week audit, then fixes scoped from what it finds.

Make the site legible to search engines

Teams whose site is slow, badly rendered, or invisible to search.

The engineering side of search: rendering, speed, structured data and crawlability. The parts that are actually code, measured rather than promised.

  • Rendering strategy (SSR, SSG, ISR) for indexability
  • Core Web Vitals and page speed
  • Crawl, indexation and site structure
  • Structured data and metadata
  • Migrations planned to protect rankings

I kept no analytics for the SEO work I have shipped, so I make no traffic, ranking or revenue claims here. What I can show is the engineering: two client sites scoring 100 for Lighthouse SEO and accessibility, with structured data and four-locale hreflang. Judge the work by that, not by a number I cannot substantiate.

PL 04

How I work

  1. Scope

    Before any code, a written scope that names the non-goals as plainly as the goals. Most projects do not fail on what was built. They fail on what nobody agreed to leave out.

    You get: A scope document and a fixed estimate

  2. Build in the open

    There is a deploy in the first week and something working to look at every week after. Not a slide showing what it will do, but a URL you can open, use, and forward to someone whose opinion you need.

    You get: A staging URL from week one

  3. Harden

    Error states, cost caps, evaluations and monitoring, before anyone calls it done. This is the part that separates a feature from a demo, and it is the part that gets cut when the build was not scoped to include it.

    You get: A load and failure report

  4. Hand over

    Documentation, a runbook and a recorded walkthrough, so the thing keeps working when I am no longer on it. The measure of a good handover is that nobody has to call me to change a value.

    You get: A repository your team can actually run

What I turn down

Fixed-price work with undefined scope, and anything where the honest answer is that it does not need a model. If a cron job and three queries would do it, I will tell you that before you have paid me to find out.

About

Lovepreet Singh, photographed at dusk
Gurugram, India

I have spent nine years building software that other people depend on, most of it at VMock, where I led engineering on a career platform used by 20,000+ students and 5,000+ employers. I left in August 2026 to work independently.

The work I care about most sits where AI meets a real product. Not demos: an orchestrator agent I built in eight weeks and put in front of a client, with routing, memory, streaming and a human in the loop, because the interesting problems only show up once something is actually in production.

Before the AI work I spent years on the unglamorous parts that make a product good: build times, bundle size, the four hundredth UI bug, the design system nobody notices when it works. That is still how I build.

These days I build for clients directly. A motel and a takeaway in regional New South Wales, both shipping in four languages, both scoring 100 for accessibility and SEO.

Small clients deserve the same engineering as large ones, and they rarely get it.

Experience

    (2 mo)

    Independent Software Consultant · Freelance

    Websites and AI features for clients directly, from architecture through to deployment.

    • Designed and shipped a four-language site for a boutique motel (alinemotel.com.au) in Next.js, TypeScript and Tailwind, with a Git-backed CMS and live room rates through a cached booking-engine proxy. It scores 100 for Lighthouse accessibility, best practices and SEO, held in CI by 110 end-to-end tests, and the owner updates all content without a developer.
    • Built a four-language restaurant site (apracurryhouse.com.au) in Next.js and Keystatic on AWS Amplify, with a weekly Playwright scraper that keeps the 102-dish delivery menu in sync and accessibility tests gating every page in light and dark. It scores 100 for Lighthouse accessibility, best practices and SEO, and the owners never update the menu by hand.
