London, UK/Since 2018

I build the thing that moves the business forward.

Hi, I’m Madyan, a full-stack product engineer in London. I work with founders and small teams to build useful software, from the interface to the backend and the AI features in between.

Full stack. Fully involved.

A person, not a handoff.

Things I’ve helped build.

Ocierge mobile app: guests browse properties

Ocierge mobile app: property details and host chat

CTO & co-founder · 2 years

Built the hotel product end to end.

Hotel teams managed guest requests in a dashboard, while guests used the mobile apps to browse properties and get in touch.

Real-time conversations: Built chat so guests and hotel teams could talk directly.
Secured $150k in Azure credits: Led the Microsoft for Startups application from start to finish.

Just Eat for Business restaurant search and food-ordering interface

Full-stack engineer · 2 years

Gave operations most of a day back.

I automated a weekly bulk-order process that had taken almost a full day, cutting it to about an hour.

Across the whole platform: Worked on customer ordering, restaurant systems and internal operations tools.
Less downtime: Tightened typing and linting, and upgraded infrastructure and developer tools.

Feedr marketing website with the Good office food homepage

Full-stack engineer · 2 years

Delivered the payment system in time for a legal deadline.

I led the Stripe integration and narrowed the scope so the business could keep accepting payments.

Marketing website: Built Feedr’s website in Storyblok, so marketing could update pages and run experiments without a developer.
Design system: Led the team that built shared components and patterns for the product.
Mentoring: Mentored colleagues in TypeScript, GraphQL and functional programming.

AgreFest landing page design with event photography and programme navigation

Web design & development · CMS website

A bilingual event site the team could update.

I designed and built the site for an event bringing agriculture and gastronomy together.

English and Turkish: Built both versions to work across screen sizes.
Easy content updates: Set up Pages CMS so the organisers could change details without editing code.

AI agent · Private client

A helping hand with lead research.

I built an AI agent to research leads for a luxury car-auction operator. It prepares a shortlist for the operator to review and decide what’s worth following up.

Open source · Developer tools

Console+: TypeScript in your browser.

I kept copying scripts between my editor and the browser. So I built Console+ to write and run TypeScript right in DevTools. A small annoyance that became an open-source project.

My approach

How I build.

Coding agents need a little context.

I give agents repo instructions, examples and checks they can run. They follow the team’s conventions, and I review the changes before they go in.

The code should sound familiar.

If the team calls it a booking, so does the code. I model the business rules with TypeScript and functional programming, so they’re easier to follow and harder to break.

Interfaces in more than one language.

I’ve built interfaces in Spanish, Portuguese, Arabic and Turkish, including right-to-left layouts. I account for local formats and labels that need a little more room.

Infrastructure that fits the business.

I weigh up cost, reliability and where data is stored. I use Pulumi to define infrastructure in typed code, so changes are easier to check and review.

About me

Hi, I’m Madyan.

I like getting to know the people behind the product.

The person using it, the person answering support questions, the teammate who knows why that bit is awkward. Those conversations help me build something that actually makes their day easier.

TypeScript mostly. Very fond of functional programming.

I get a little excited about an elegant type system. Happy to explain. Equally happy to spare you.
