William Louth

AI Product Architect | May 2026 – Present

• Designed the product and cognitive architecture for PAIR, an AI companion for professional practice centred on situational awareness and human–AI collaboration.
• Defined a reusable world model of situations, agents, context, roles, norms, tasks, place and time, with a Prepare, Act, Reflect, Feed-forward learning loop in which AI supports preparation, interpretation, reflection and follow-through.
• Built a type-driven architecture in which domain experts define situation patterns that the agent recognises and binds to live context at runtime, extended into semantic task management, persistent professional context and structured interaction through reading cards, bounded prompts and proactive proposals.

Migration and Integration Architect, Engineering Lead | Jan 2026 – May 2026

• Architected a reusable migration and integration framework for learning management systems around a canonical intermediate domain model that decouples source and target schemas and preserves business rules, relationships and data semantics.
• Designed a compiler-inspired Record, Rectify, Replay pipeline with multi-pass transformation, enrichment, cross-object validation and controlled synthesis into target APIs and database operations.
• Built traceability into the pipeline through transformation logs, identifier mapping, auditable checkpoints and post-load verification, making migrations repeatable across evolving schemas.

Digital Twin Architect | Apr 2025 – Dec 2025

• Worked on observability and digital twin initiatives across manufacturing, logistics, defence and retail, helping organisations design, engineer, observe and manage mission-critical systems of systems.

Software Architect, Engineering Lead | Jan 2024 – Dec 2024

• Served as domain architect for savings, investment and banking-assurance products within the bank’s Future Ready transformation, spanning cloud architecture, API design, platform engineering and service design.
• Initiated and led design and development of the Devƒ(x) accelerator toolkit, encapsulating serverless AWS development (queues, step functions, Lambdas and gateways) in reusable constructs that standardised delivery of business workflows, processes and services.
• Designed an agentic AI workflow integration through a Tasks OpenAPI.
• Grew the skills of solution architects, software engineers and information analysts in high-code development, systems engineering and service design.

Autoletics | JVM product line | Jan 2008 – Jan 2019

• Designed and built a commercial JVM product family progressing from measurement to control, execution memory and simulation, used for performance engineering by enterprises including PUMA and Yapı Kredi.
• JXInsight: application performance profiling and transaction analysis with distributed tracing for the JVM.
• Satoris: adaptive multi-strategy dynamic metering for low-latency applications, including gaming and trading platforms.
• Sentris: application-level quality of service unifying activity metering, execution control and resource management in one runtime model.
• Stenos and Simz: execution recording and playback, and a discrete-event simulation engine that replays the execution behaviour and resource consumption of an entire instrumented infrastructure in near real time within a single runtime.
• Pioneered activity-based cost metering for applications, runtimes and platforms.

Principal Engineer, Product Architect, CTO Office | Feb 2019 – Apr 2020

• Continued development of Signify after selling its intellectual property to Instana, and led the Signals API work for expressing service health across distributed services.
• Designed new API components and cost-optimised data pipelines on AWS for the SaaS product, including stores holding more than 100 billion records.
• As the second member of the CTO Office, shaped observability and monitoring product strategy over a 6 to 18 month horizon, focused on contextualisation, complexity reduction, controllability and communication. Initiated AssistiveOps.
• Encoded domain expertise in signal types that pre-classify operational evidence and expose relationships across process timescales.
• Wrote The ABC of Observability and further articles on enterprise observability engineering.

Applications Operations Management, Architecture Team Lead | May 2006 – Feb 2008

• Provided ITIL expertise in change, configuration and release management, and in application and service monitoring.
• Built a software build artefact repository on the Java Content Repository API across the Jackrabbit, Day Software and eXo Platform implementations.

Technical Solutions Architect, Advisor | Nov 2003 – May 2006

• Architected and built, with three engineers, a model-driven migration solution from ServiceDesk 4.5 to 5.0.
• Built a distributed WorkManager implementation that parallelised transformations across machines and JVMs for databases of hundreds of millions of records.
• Led performance and availability engineering for the CME platform across R&D and customer environments.

JDBInsight | Java transaction analysis product | Jan 2003 – Oct 2003

• Created JDBInsight, a Java transaction analysis product with performance visualisations for developers, testers and database administrators, winner of the JDJ Readers’ Choice Award for Best Java Application Monitoring Tool.

Founder, Computational Systems Researcher | May 2020 – Present

• Designed and built Substrates, a high-performance runtime for deterministic, ordered signal processing and state propagation: single-threaded circuits, ordered causal propagation, typed signal pathways, adaptive flow control and composable in-flight transformation, with explicit execution semantics at very high rates of local signal circulation.
• Designed Serventis, a semiotic signal model that turns operational evidence into signs, statuses, situations and projections, giving human operators and autonomous agents a shared basis for understanding and bounded intervention.
• Researches situational intelligence and human–AI collaboration, drawing on semiotics, cybernetics and perceptual control theory.
