Open-Core, Provider-Agnostic Publishing Engine

An open-core, provider-agnostic publishing server designed to automate the lifecycle of filesystem-based content assets, ranging from blogs and documentation to AI datasets. It manages the pipeline from raw file submission to consolidated daily release batches, strictly isolating core domain rules from external storage and VCS providers through pluggable strategy drivers. Built as a monorepo, it supports both lightweight, cloud-native serverless deployments and dedicated multi-tenant server setups. Read the blog post about it.

Template-First Publishing CLI

A transaction-safe, modular CLI designed to automate content creation and template rendering workflows. Built with a pluggable "Lego set" architecture, it features a blueprint-driven pipeline that supports interchangeable template engines, custom JavaScript middleware stacks, and dynamic frontmatter generation. It manages the local content lifecycle from initial draft rendering to Git-integrated dispatch workflows with atomic rollbacks, deep event-bus observability, and extensible toolpack utilities. Read the blog post about it.

Automated RSS Content Syndication Engine

A self-contained GitHub Actions solution built to syndicate RSS feed content across multiple social platforms in strict chronological order. Features an isolated, sequential matrix strategy that broadcasts new posts to platforms like Mastodon, X, Nostr, Bluesky, and LinkedIn while isolating provider failures. Manages persistent tracking state via GitHub Actions cache primitives, supporting both self-contained automated execution and caller-repository workflow integration. Read the blog post about it.

Local GPU-Accelerated LLM Workflows

A local AI development setup utilizing hardware acceleration to run open-weights Large Language Models locally. Focused on building reproducible, containerized local AI environments via Devcontainers, passing local GPU compute directly into isolated development spaces for offline inference, prompt engineering, and LLM-assisted software development without external API dependencies or cloud latency. Read the blog post about it.

OAuth 2.0 REST API & React Web Client

A full-stack, end-to-end TypeScript application featuring a custom OAuth 2.0 REST API backend and a responsive React frontend. Built to demonstrate secure authentication standards, clean API architecture, and seamless state management across the stack. Features structured token handling, strongly typed request/response schemas, and a modular client interface optimized for scalable user session workflows. Read the blog post about it.

Static site generator

I upgraded my Nodejs based static site generator to be a much more generalised website generator. It's extremely flexible and customizable.

Some of it’s major features include renderers, middleware & renderer pipelines, server side components, incremental progressive rendering, plugins and packaging and data loading utilities.

I wrote a blog series that describes it's functionality, as well as a longer term vision plan for the project.

Making a Squarespace website dynamic with a serverless API, frontend page hydration and search

I built some serverless API endpoints that pull data from Monday.com, and a javascript frontend that inserts the API data into the page and also provides search functionality with filtering and date sorting of results. Deep Tech Jobs has since successfully launched.

Jamstack Architecture Content Sites

I built a NodeJS static site generator for my blog website, notes website, linkblog website and podcasts website.

Contributions can be easily created using a browser bookmarklet. New content gets added to a Github repo feature branch. Backend processing is done using Serverless functions. The feature branch is merged into the main branch on a schedule and the site is automatically rebuilt and deployed.

Serverless books API

serverless-books-api - Implements a Books API for a Library, intended to be run on AWS Lambda/DynamoDB using serverless

• Functions run on AWS Lambda
• Data is stored in AWS DynamoDB
• Uses domain driven design techniques with handlers/utilities/adapters layers

Internet of Things App

internet-of-things-app - System to collect and process realtime data of devices in an iot fleet

This project is an MVP of an Internet of Things (IOT) application. The scenario is one where there are devices that are geographically distributed and are moving, so could be delivery or perhaps passenger vehicles. The application receives data updates from devices, proceses the data and then displays the data. In this specific example the device speed is calculated. Generally speaking it is a way to collect and process realtime data.

Freelancer

freelancer - Website for freelancers with homepage and payments pages to securely receive payments for services.

Website for freelancers that runs sites. Each site can be static and/or dynamic, you can easily associate domain names to each site and adding a site is as simple as creating an express app and adding it to the apps folder. Payments are handled by Stripe and email notifications are via Mailgun.

Linkblog.io

Linkblog.io was the minimalist link curation tool, a cloud/SAAS NodeJS web application for managing your daily links. I created the infrastructure, the automated server provisioning system, the code build and deployment system, developed the website and REST API, and the fault tolerant backend that processed jobs using a scheduler, message queues and webhooks. There were robust unit and integration test suites for all the NodeJS code.
