Impact
How the Work Is Actually Built.
A couple of the engineering problems behind these projects, and the decisions that kept them from becoming the usual mess.
AI Systems
Customer Support AI
The hard part of support automation is not producing an answer. It is deciding when not to answer, and when to hand the conversation to a human.
AI Systems
Cashbook AI
Automatic transaction categorization is worthless unless the user can correct a wrong call, and the system keeps that correction.

FAQ
Frequently Asked Questions.
Everything people usually want to know before starting a project.
A Forward Deployed Engineer embeds inside the customer's team rather than working behind a ticket queue. They learn the real workflow first hand, then design, build, deploy and iterate the system in the customer's own environment until it holds up against real users and real data.
Yes. FDE is how the engagements here run: he joins your team, tools and codebase, watches the workflow being done, then ships the system end to end in your environment. It is the same person doing discovery, architecture, implementation and the iteration after launch.
Roughly three phases. Deploy in: time with the people doing the work, inside your repo and tooling. Ship a narrow slice: one real path working end to end, early. Widen and harden: automate the routine path, route exceptions to a person, instrument everything, hand over documented.
A contractor builds to a specification you wrote; an FDE helps you find out what the specification should have been, because they are in the room while the problem happens. There is also no handoff: the person who understood the problem is the person who writes and deploys the code.
Cost follows scope, so it is quoted per project rather than from a rate card. Most engagements run one of two ways: a fixed price against an agreed scope, or an ongoing contract when the work is continuous. Send the problem you are solving and you will get a scoped estimate back.
Both. Plenty of the work here is an addition to something already running rather than a rewrite, including custom booking logic built as a WordPress plugin so a theme update never touches it. The first step on existing code is reading it and telling you honestly what shape it is in.
Remote-first, with clients worldwide, from Karachi, Pakistan. Work is handed over in writing rather than depending on a shared working window, so progress does not stall waiting for an overlap. Project enquiries usually receive a reply within one working day.
Across the projects documented on this site: AI support and categorization systems, payroll and ERP platforms, healthcare booking, ecommerce and marketplaces, real-time chat, fleet and logistics tooling, ESG reporting, and manufacturer catalogues. The engineering write-up for each one is on the Impact page.
Tanzeel Naveed Khan is a Forward Deployed Engineer (FDE), full stack developer and AI engineer who builds AI-native web applications and intelligent automation systems embedded with the client's team. He works across the whole stack, from Next.js and React front ends to Python and Node.js back ends, and ships from concept through to deployment.
Forward deployed engineering (FDE) engagements, full stack web development, AI agent development and workflow automation. That covers embedding with a client team, building custom web applications, integrating AI models such as OpenAI and Claude into products, connecting payments and databases, and architecting systems designed to scale.
His core stack is Next.js, React, TypeScript and Tailwind CSS on the front end, with Node.js and Python on the back end. He also works with MongoDB, Firebase and Stripe, and builds AI features using the OpenAI and Claude agent APIs.
Yes. He is currently available for new projects and forward deployed engineer (FDE) roles, and works remote-first with clients globally. Engagements range from single-feature builds and AI integrations to embedding with a team and delivering a complete application end to end, on either a project or ongoing contract basis.
