About Lawrence Johnson
Systems Architect & Data Engineer. M.S. Mathematics. Building enterprise-grade systems combining formal verification, geospatial intelligence, and operational optimization.
Maffclub Platform
A verification-first platform combining formal proofs, AI agents, and geospatial intelligence for high-impact decisions.
Consulting & Advisory
I apply the same methods to help teams deliver verified, scalable systems and data platforms.
I'm Lawrence Johnson, a systems architect and data engineer with deep expertise in formal verification, geospatial analysis, and enterprise systems design. I hold an M.S. in Mathematics, which underpins my work in predictive modeling, statistical optimization, and formal methods verification.
I solve complex business problems by combining rigorous systems architecture with data-driven intelligence. My technical depth spans FastAPI backends, Next.js frontends, distributed services (microservices, message queues, database optimization), statistical modeling, spatial analysis (GeoPandas), and cloud infrastructure with Docker and Kubernetes. I also integrate Lean 4 formal verification and AI orchestration for systems requiring provable correctness.
I partner with enterprises, government agencies, and founders who need technical leadership on correctness, scalability, and operational efficiency. Recent work includes formal verification systems for fintech compliance, geospatial intelligence platforms directing $M+ in resource allocation, and ETL automation reducing operational overhead by 40%+.
My focus is on infrastructure, distributed systems, formal verification, and data engineering solutions that scale reliably while reinforcing correctness in mission-critical domains.
