Project: Build, in microservice architectural style, of an information system for electricity Supply & Demand balancing on the French electricity network, in adequacy with European electricity market directivesThe main goal of the project is to improve the reaction to the market and electricity network events towards real-time, and reach human operators workload automation to optimize the electricity market and network security• Led business requirements definition workshops with heterogeneous clients: challenged and helped anticipating requirements evolution in time, extended scope with technical requirements and key indicators, defined acceptance criteria• Led and designed the architecture: microservices, security, high availability, scalability, resilience, observability, configurability• Produced HLD/LLD and technical documentation• Designed and implemented a test strategy (unit, integration, end-to-end, non regression, load and performance), and tooling for a maximum of automation• Designed and built the CI/CD pipelines• Took part in and leveraged a Safe agile organization to reach the project goals in terms of quality, time to market and cost effectiveness • Designed, developed and tested critical and complex features• Leveraged our network of experts, and accelerator code repositories to raise the team productivity, accelerate the build phase while hardening and empowering our solution with already proven components• Led a hand-in-hand collaboration with the stakeholders to reach deployment success and KPIs fulfilment• Designed and led optimizations on critical features to achieve significant performance improvement and reach acceptance• Continuous technology watch, new solutions studies, implemented proofs of concept

Project: Reengineering of a monolithic data warehouse for electricity telemetry and ground events, sourced from the French electricity transport network, into a robust, scalable, reactive microservice styled data service platform for hot (near real time) and lukewarm (> 1 min) data, towards other systems (~ 400 applications) in RTEThe main goal of the project is to serve electricity network data and events near real-time to the rest of the information system (~ 400 applications) in order to improve the company business processes reactivity to the electricity network events, while ensuring reliability and scalability to data volume and client applications increase over time.• Analyzed the existing system in terms of functionalities, strengths and flaws • Led business requirements definition workshops with heterogeneous clients: challenged and helped anticipating requirements evolution in time, extended scope with technical requirements and key indicators, defined acceptance criteria• Searched for new business process opportunities, new sponsors, and extended the budget for the project based on an extended scope• Convinced the sponsor board to transform the project scope into a data service infrastructure with a service level agreement• Estimated and negotiated budgets for the new project scope• Formalized non-functional requirements : High availability, scalability, resilience, service level objectives on hot (<20 seconds) and lukewarm (>1min) data, service equity between client applications• Subdivided the project scope into smaller manageable sub-projects, designed a development strategy with a compressible-flexible planning in order to mitigate the project strong exposure to the company other biggest projects risks• Designed and planned a migration strategy from the old existing data warehouse to the new data service platform in a time sensitive multi-client context, with risk/impact/mitigation (preventive/curative) and rollback options plan• E.T.C.
