About Simon
Independent Senior Full-Stack Engineer | Enterprise Java, Agentic AI & MarTech
I am an independent senior full-stack engineer specializing in enterprise Java (Spring Boot), Agentic AI automation, and high-ROI MarTech ecosystems. By operating entirely independently with zero agency bloat, I provide B2B and enterprise clients with direct access to senior technical execution at a highly competitive, direct-to-expert rate.
My Dual-Threat Expertise:
Enterprise IT & AI: I build highly scalable microservices (AWS/GCP, Kubernetes), robust Big Data pipelines (Kafka, NiFi, ElasticSearch), and privacy-first Agentic AI integrations (federated learning, OpenAI, Llama) that eliminate manual bottlenecks.
MarTech & Revenue Growth: Unlike traditional developers, I bridge the gap between complex infrastructure and customer acquisition. I engineer technical SEO foundations, high-converting WordPress platforms, and automated CRM pipelines that directly drive revenue.
Why Partner With Me?
Zero Agency Overhead: You get top-tier engineering expertise without the standard 50% agency markup.
Proven Business Impact: From building predictive AI supply chains to scaling digital ad revenues by 20x, I write code that measurably improves the bottom line.
End-to-End Ownership: I take full ownership of the digital pipeline—from secure REST APIs and database schemas to conversion-optimized front-end lead generation.
Let's build systems that scale and platforms that convert. Reach out to discuss your backend infrastructure or AI automation needs.
