I have 5 years of experience building data-rich web applications, creative visual interfaces and interactive business intelligence dashboards. My specialisation is in relationship mapping through network/graph visualization with D3.js, PIXI.js and Neo4j. I specialize in helping clients build prototypes from the ground up to showcase business ideas or technological opportunities, while writing production-quality code and designing robust system architectures. I approach each project with scalability in mind, ensuring that the prototype can evolve seamlessly into an MVP and, ultimately, a production-ready application. I have good design and user experience sensibility, so that I can work with or without a designer. I iterate over designs with code. Know-how: - Designing and creating data viz, from simple chart types to custom high-density visuals, with Javascript/Python in either object oriented or functional paradigm - Creating React/Next.js or Svelte-based web applications from the ground up - Creating reusable and responsive UI layouts and components with CSS/Tailwind CSS/Chakra UI from existing Figma designs - Designing and creating network/graph visualizations with D3.js, PIXI.js - Neo4j set-up, graph modelling, data import, cypher querying - Handling complex data structures and creating data processing pipelines - Creating backend-for-frontend APIs with Node.js, Express or Flask - Postgresql database (Supabase) set-up, schema creation and querying - App deployment to platforms such as Vercel, Netlify, AWS. I understand the importance of Typescript and unit testing with Jest, but am still not an expert in either. Nevertheless, I am keen to work on Typescript-based apps. Recent interest: - Generative AI: Knowledge graph construction from unstructured and structured documents with LangChain, LLM, OpenAI, Neo4j - Generative AI: Neo4j graph-based Retrieval-Augmented Generation (RAG) system, experimenting with various RAG techniques - Prompt engineering
