About

Professional summary

I am a Senior Engineering Manager with more than 20 years of software engineering experience, specialising in backend, platform, and data organisations. I combine hands-on distributed-systems expertise with people leadership, organisational design, and reliable engineering delivery.

I have led multi-team organisations of up to 15 engineers through technical leaders across European scale-ups. My leadership approach focuses on developing senior engineers into leadership roles, building effective teams, and creating clear ownership across product, data, and engineering.

I have extensive experience defining technical strategy for backend and data platforms, including event-driven systems, cloud-native services, reliability initiatives, and platform migrations. I have worked with high-scale analytics, telephony, identity, property-data, financial, and blockchain systems.

I am experienced in cross-functional planning, hiring, performance management, incident management, and engineering execution. I have delivered measurable improvements in cloud cost, latency, platform reliability, and enterprise-client delivery.

I am currently pursuing independent Python and AI application projects while remaining technically current. I am open to senior engineering management and leadership opportunities where I can help teams scale, strengthen their platforms, and deliver strategic business outcomes.

Career Break and Independent Projects Personal Projects

I planned a career break after nearly 20 years of continuous professional work. During this period, I have remained technically current through independent Python and AI application projects.

Senior Engineering Manager PriceHubble

I led two distributed teams through two technical leads, managing nine engineers across a property-data platform and an acquired product team operating across several European locations. I partnered with the CDO and product and data leaders to define a six-month strategy and roadmap for the scraping domain.

I integrated an acquired senior engineering team by aligning ownership, roadmaps, and delivery practices. I reduced GCP costs by about 60% through a cloud-usage audit, improved observability and incident response for pipelines ingesting data from more than 30 advertising sites, and delivered an LLM-based sales-contract extraction pipeline.

Engineering Manager, Backend, Data Platform Aircall

I led up to 15 engineers across backend, data, and identity teams through two technical leads. I scaled the distributed analytics organisation, expanded its scope into authentication, and drove hiring across backend, frontend, and data roles.

I led migration of critical telephony services from a legacy monolith to AWS serverless architecture, reducing incoming-call setup latency from approximately two seconds to 0.2 seconds. I also set direction for a next-generation event-driven data platform, coordinated migration across more than 10 engineering teams, and led organisation-wide reliability initiatives.

Senior Software Engineer Global Relay

I built a REST API gateway for asynchronous backend services. I also created an OpenShift template generator to standardise service creation and deployment practices.

Senior Software Engineer, Contract Luther Systems

I delivered and refactored distributed backend services for enterprise blockchain applications. My work used Go, Lisp, gRPC, Docker, AWS, and Hyperledger Fabric.

Lead Software Engineer, Contract GfK

I led a seven-person backend team building a cloud-native market-data analytics platform across AWS and GCP. I consolidated proofs of concept into a production platform and migrated workloads to Kotlin and Python services.

I introduced automated performance testing and conducted more than 100 technical screening and coding interviews. This supported the creation of three backend engineering teams.

Senior Software Engineer, Contract Leo Tech Services

I built Groovy and Spring Boot microservices for a sports-betting platform. The work focused on backend service development in a microservices environment.

Associate, Contract Transform / Health Education England

I delivered backend services and data-warehouse integrations. I also created reusable ETL templates to support data engineering delivery.

Associate, Contract Equal Experts / Camelot and Loterie Romande

I developed shared microservice libraries used across more than 30 services. I also reviewed active-active data-centre architecture.

Engineering Lead, Contract Buildit / HSBC and Lloyds Bank

I led a six-person delivery-recovery team. I assessed architecture and agile delivery practices to help improve programme execution.

Senior Software Engineer, Contract Yoti

I architected Kafka-based event-driven microservices for a greenfield digital identity platform. My work focused on scalable distributed backend architecture.

Technical Architect IG

I defined a roadmap for migrating from a monolith to microservices. I improved CI/CD practices across 18 websites and served as a hiring manager.

Senior Developer Cisco Systems

I optimised an asynchronous HTTP proxy. I also designed a highly available log-shipping architecture.

Lead Developer and Scrum Master EPAM / UBS and Hotels.com

I led teams of up to nine engineers across client engagements. I reduced hotel-search latency from approximately 10 seconds to under two seconds and built sub-two-millisecond FX components.

I also conducted more than 200 interviews and supported engineering delivery through technical leadership and Scrum practices.

Developer EPAM / William Hill

I implemented Java and Spring persistence components and core betting business rules. My work supported backend development for a betting platform.

Developer Ericsson

I developed Java and C++ telecommunications software. I also created an internal client-server application.
