Project details
Most databases struggle with connected data. Neo4j thrives on it, but only when the graph is modeled and queried the right way.
I help founders, engineers, and data teams design, build, and optimize Neo4j databases that are fast, scalable, and production-ready. Whether you're starting from scratch or untangling an existing schema, I bring both the technical depth and the graph-first thinking to get it right.
I don't just write Cypher. I help you think in graphs.

Build AI Contract Processing Tool Extract, Summarise & Organise Agreements (Internal Build)
JD is amazing! He built us a custom AI document processor that saves our team hours every week, and the accuracy is so much better now. We got a really polished Next.js web app with document automation, AI search, and a chatbot, all powered by OpenAI and Claude. He's super sharp, easy to chat with, and he just got what our business needed. Can't recommend him enough for AI, document automation, or web app work!

Custom Invoice & Pricing System — Process Design + Software Build
JD came in to fix a pricing and invoicing problem that had been costing us money. Instead of just building what we asked for, he stepped back, understood our workflow, and redesigned the process so misquotes simply couldn’t happen anymore.
He then built a custom invoice system that removed guesswork, sped things up, and made our pricing far more consistent and profitable. The impact was immediate.
Fast execution, clear communication, and very strong technical judgment. If you want someone who thinks like a partner and delivers real business results, JD is a great hire.

AI-Powered Neo4j Knowledge Graph & Document Intelligence Platform (SaaS Build)
We hired JD for a complex AI + Neo4j knowledge-graph prototype, and he delivered far beyond what we thought was possible in just two weeks. He ingested our ERP + email data, built an intelligent entity-resolution pipeline, and produced a fast, working MVP with clear architecture docs and a scalable design. Communication was perfect, execution was fast, and the technical quality was top-tier. If you need AI-powered data extraction, knowledge graphs, or document intelligence, JD is the person you hire.

Job Success
Accra, Ghana - 3:37 am local time
Some results I’ve helped clients achieve include:
- Automated the processing of 1M+ documents per month, reducing HR costs significantly with an AI-powered SaaS platform.
- Scaled an audio streaming app to 30,000+ daily listeners within its first two months.
- Increased operational efficiency by 80% by building enterprise automation tools that enabled seamless coordination of 1,000+ volunteers and large scale meetings
If you’re here, you probably want systems that just work... and keeps working as you scale.
Maybe you've worked with freelancers before who left you with buggy code, constant delays, or tools that looked great but didn't solve the real problem.
What you actually need is a partner you can trust to own the project and deliver a solution that just works, no excuses.
👉 I’m JD, an AI automation-focused full-stack developer and Neo4j Certified Professional with 8+ years of experience building user-focused systems and applications.
My work has contributed to products serving over 1 million users, achieved by balancing technical quality with real business impact.
Today, I specialize in helping high-growth SaaS teams launch MVPs quickly and helping businesses replace manual processes with scalable, AI-powered solutions.
I specialize in delivering end-to-end high-performance, scalable digital solutions. I’ve delivered high-impact solutions such as:
- AI-powered agentic workflows that cut costs and unlock new capabilities.
- Data dashboards and visualizations that drive better decision-making.
- Streaming platforms that handle large-scale audio and video reliably.
- Seamless payment systems that improve conversion and retention.
- Location-based apps that enhance user engagement.
- Graph-powered insights that uncover hidden relationships and improve decision-making (Neo4j, GraphRAG).
If you’re dealing with messy workflows, manual processes, or systems that don’t scale…
Let’s fix that.
I start every engagement with a short scoping session to map out the highest-leverage automation and system improvements for your business.

Steps for completing your project
After purchasing the project, send requirements so John-Dag can start the project.
Delivery time starts when John-Dag receives requirements from you.
John-Dag works on your project following the steps below.
Revisions may occur after the delivery date.
Requirements Gathering & Data Understanding
We start by understanding your goals, datasets, and desired outcomes. I’ll review your existing data sources, entities, and relationships to determine how they translate into a graph model.
Neo4j Graph Data Model & Architecture Design
Next, I design the graph schema, including nodes, relationships, and key properties. This phase also defines indexing strategy, constraints, and the overall architecture needed for efficient queries and scalability.
