About me

Six years of building real products

I've spent the last 6 years building web apps for healthcare, automotive, e-learning, legal and SaaS companies, mostly with Angular, React / Next.js and Node.js / NestJS. For two and a half years I led a team of 4–6 developers: planning sprints, reviewing code and getting releases out on time.

What I'm good at: turning a messy brief into a clear plan, writing code the next developer can understand, and telling you early when something won't work.

Ways I can help

Pick one, or a mix. Most projects end up touching a few of these.

Frontend & Angular Development

New Angular apps, or new features and upgrades for the one you already have.

React & Next.js Development

React and Next.js sites and apps that load fast and show up on Google.

MEAN / MERN Stack Solutions

The whole product: database, API and frontend, built by one person who understands all of it.

Advanced Backend & APIs

REST APIs and backend services in Node.js, NestJS or FastAPI, with sign-in, background jobs and a sensible database design.

Cloud & Serverless (AWS)

AWS Lambda, S3 and CI/CD pipelines, so deployments are routine and hosting costs make sense.

Custom E-commerce Systems

Custom stores and ordering systems for when an off-the-shelf platform doesn't fit how you sell.

Web Scraping & Automation

Scrapers and scheduled jobs that collect, clean and sync data for you.

Corporate Web Presence

Company websites that look professional, load fast and are easy to update.

Enterprise Java Development

Java EE, Spring Boot and Hibernate applications for larger organisations.

Workflow automation

How I can automate your workflows

If your team copies data between tools, puts together the same report every week or types up documents by hand, that work can usually run by itself. I build automations that are reliable, logged and easy to change later.

Documents to data

Pull names, dates, totals and IDs out of PDFs, scans and emails, and put them straight into your system.

Connect your tools

Keep your CRM, spreadsheets, accounting and internal apps in sync, so nobody types the same record twice.

Reports that build themselves

Daily or weekly reports and dashboards, put together and sent automatically.

Alerts that reach the right person

Email, SMS, WhatsApp or push alerts when something needs someone's attention.

Scheduled jobs

Imports, clean-ups, scraping and syncing that run on time, with a log of every run.

A person stays in charge

Routine cases are handled automatically. Unusual ones go to the right person to review.

  1. 1

    Free workflow review

    A short call to map what your team does by hand and where the time goes.

  2. 2

    Plan

    A written plan: what gets automated, what stays manual, and what it costs.

  3. 3

    Build

    Built in small steps and tested on your real data, with logs for every run.

  4. 4

    Handover

    Documentation, a walkthrough for your team, and support after launch.

Recent work includes document screening for compliance teams at Vantage AIS and process automation for FixedOps Innovations.
