AI Engineering Lead and PhD researcher in AI/ML, certified in Claude by Anthropic. I design and ship production systems built around Claude: agents, RAG pipelines, and automations that actually make it to deployment Over the past 7 years I've helped more than 20 companies put AI into production across the US, Europe, and the Middle East. I've led engineering teams at startups large and small, and I bring a consistent track record as a high performer on the work I take on I post regularly on Medium, X, and YouTube on the latest in AI, ML, and tech, which keeps me on top of how fast the field moves, with an audience of over 10,000 across platforms. I share this work publicly partly because teaching a thing is the best test of whether you understand it What I build: - RAG chatbots and agents over your documents, PDFs, Notion, and knowledge bases - LLM fine-tuning on your domain data - Workflow automations that replace 40–80% of manual operations - Solution architecture, so you commit to the right stack the first time - Recovery work on stalled or underperforming AI projects Send over the project and I'll reply the same day with a plan, a clarifying question, or an honest pass

I’m a senior AI systems and full-stack engineer with deep experience designing, building, and shipping production AI products end to end. I specialize in turning complex ideas into reliable, scalable systems that actually work in the real world. My background spans AI/ML pipelines, backend systems, and modern web applications. I’ve led and contributed to projects involving large language models, multimodal analysis (video/audio), RAG architectures, automation pipelines, and subscription-based SaaS platforms. I’ve worked both as a freelancer and as a lead engineer on internal AI products used by real customers at scale. What I do best is bridge the gap between research and production. I don’t just prototype. I design systems that handle edge cases, cost constraints, performance targets, and long-term maintainability. That includes API design, data modeling, infrastructure decisions, and clear handoffs to frontend or product teams. Core strengths: → AI, Agents & LLM Systems: RAG pipelines (LangChain, Pinecone), Model Context Protocol (MCP), OpenAI/Gemini/Whisper, and custom evaluation frameworks. → Backend Engineering: Java Spring Boot, .NET, Python, Ruby on Rails, Node.js, PHP. → Workflow Automation: Complex orchestration using n8n and Zapier to connect AI agents with business logic. Full-Stack Apps: React, Next.js, TypeScript, .NET, Java, PHP, Ruby on Rails, Supabase, Stripe, and secure authentication flows. Data & Infrastructure: Postgres, MySQL, Docker, AWS, and CI/CD pipelines. I’m especially strong in AI products that involve: ✓ Advanced RAG: Retrieving context from complex datasets (PDFs, Databases) for accurate LLM responses. ✓ Multimodal Analysis: Processing Text, Audio, and Video inputs. ✓ Structured Outputs: ensuring JSON reliability and strict evaluation logic. ✓ Cost-Aware Workflows: Optimizing token usage and latency. ✓ Human-in-the-loop Systems: Designing approval flows for critical AI tasks. Clients hire me when they need someone who can think like an engineer, a product owner, and a business operator at the same time. I ask the right questions up front, communicate clearly, and deliver systems that are built to last. If you need help designing a robust RAG system, stabilizing a backend, shipping a full product, or untangling an automation workflow that’s gotten too complex, I can help. Happy to jump on a call and talk through your problem before writing a single line of code.

How to Hire Top Neo4j Developers

How to hire Neo4j specialists

Neo4j specialists can help you leverage the power of flexible, fast, and efficient graph databases for your apps. 

So how do you hire Neo4j specialists? What follows are some tips for finding top Neo4j specialists on Upwork.

How to shortlist Neo4j professionals

As you’re browsing available Neo4j consultants, it can be helpful to develop a shortlist of the professionals you may want to interview. You can screen profiles on criteria such as:

  • Technology fit. You want a Neo4j specialist who understands the technologies in your application stack. 
  • Project experience. Screen candidate profiles for specific skills and experience (e.g., using Neo4j with a Node.js-powered web app).
  • Feedback. Check reviews from past clients for glowing testimonials or red flags that can tell you what it’s like to work with a particular Neo4j specialist.

How to write an effective Neo4j job post

With a clear picture of your ideal Neo4j specialist in mind, it’s time to write that job post. Although you don’t need a full job description as you would when hiring an employee, aim to provide enough detail for an independent contractor to know if they’re the right fit for the project. 

An effective Neo4j job post should include: 

  • Scope of work: From eliminating duplicate data sets to designing graph databases, list all the deliverables you’ll need. 
  • Project length: Your job post should indicate whether this is a smaller or larger project. 
  • Background: If you prefer experience with certain database technologies or developer tools, mention this here.
  • Budget: Set a budget and note your preference for hourly rates vs. fixed-price contracts.

NEO4J SPECIALISTS FAQ

Frequently asked questions

What is Neo4j?

Neo4j is a graph database management system for creating ACID-compliant databases with native graph storage and processing. Instead of storing data in a static table, graph databases store the relationships between data points. This makes graph databases ideal for highly interconnected data sets and complex queries. 

Here’s a quick overview of the skills you should look for in Neo4j professionals:

  • Neo4j
  • Software development
  • Data science
  • Database management 

Why hire Neo4j specialists?

The trick to finding top Neo4j specialists is to identify your needs. Is your goal to migrate your database from relational to graph with Neo4j? Or are you trying to build an internal job recommendation engine to find the right person for a project based on known skills, positions, and certifications? 

The cost of your project will depend largely on your scope of work and the specific skills needed to bring your project to life. 

How much does it cost to hire a Neo4j specialist?

Rates can vary due to many factors, including expertise and experience, location, and market conditions.

  • An experienced Neo4j specialist may command higher fees but also work faster, have more-specialized areas of expertise, and deliver a higher-quality product.
  • A contractor who is still in the process of building a client base may price their Neo4j services more competitively. 

Which one is right for you will depend on the specifics of your project.
