Making easy to manage access to critical cloud systems and resources.

Built a resilient & highly scalable task queue in Go & MySQL to reliably deliver millions of daily notifications while meeting strict requirements of introducing no additional infrastructure.

- Feature Lead for several facets of the Snyk Cloud and Snyk IaC plus.- Converted and improved the Fugue Cloud Security Posture Management (CSPM) tool from AWS (step functions, Lambda functions, ECS, etc) to Kubernetes.- Built the API using OpenAPI standards using Go and Postgresql deployed to Kubernetes.- Developed ETL processes and data pipelines using Temporal.- Optimized the performance and availability of microservices, ensuring smooth operation and high uptime.- Replaced a standard Debezium CDC (change data capture) connector utilizing the database commit log with a novel implementation based on the highly adaptable Outbox Pattern.- Re-architected the DW and reduced the costs by a factor of 3.

- Developed the Fugue, a highly scalable and dependable CSPM tool that utilized the Terraform providers from the three leading cloud providers and conducted security vulnerability assessments of customer cloud environments.- Implemented a modular monolith-based architecture using Python and Go on AWS proprietary services such as Lambda, ECS, SNS/SQS, Aurora ensuring high availability and fault tolerance.- Developed an Role-based access control (RBAC) for the CSPM app.- Collaborated closely with security and compliance teams to define and implement custom rules and policies aligned with industry standards and regulatory requirements.- Developed the Data Warehouse using AWS Glue to build ETL pipelines and Redshift and S3 Parquet to store the data.- The absence of customer churn and the platform's significant growth led to its acquisition by Snyk.

- Architected and developed the Neutron Reduction Web Portal (Python Django with Celery-Redis backed by PostgreSQL and deployed with Docker with ETL jobs running on a in-house cluster)- Blue Sky research projects using AI, Machine Learning (Scikit Learn and TensorFlow) to classify and predict experimental data, and GPU processing (CUDA) of mathematical models.- Active contributor to the open source scientific projects Mantid (www.mantidproject.org) and SasView (www.sasview.org).

In charge of reviewing and analysing existing neutron data reduction software as well as programming practices of scientific software developers.Defined a common data analysis infrastructure for neutron reactor sources.Feasibility study and prototype development in C++11 based on the Mantid Framework.Designed and led the development of the Live Data Analysis platform at the ILL: Python Flask RESTful Server with seamless integration with both legacy and recent data reduction software.

Development of new methodologies, algorithms and UIs for X-ray data collection strategy planning taking into account radiation damage.Development of computer vision routines to render 3D models of micrometre crystals from both visual images and crystal morphology prediction algorithms.Official ESRF tour guide. Lead many outreach activities communicating ESRF science to the general public in three languages (English, French and Portuguese).

Development of new instrumentation for the application of absorption corrections to macromolecular crystallographic X-ray diffraction data using a 3D crystal model generated photographically.Emphasis on image processing, wavelet transformation and Shape from Silhouettes (OpenCV and ImageJ)Joint X-ray and neutron studies of DNA oligonucleotides. Thesis title "X-ray and neutron macromolecular crystallography new methodologies and structural studies on DNA oligonucleotides". Joint collaboration between Keele University (UK) and the the ESRF & ILL (Grenoble).

Designed and developed a J2EE 3-tier system architecture for the Information System for Protein Crystallography Beamlines (ISPyB). The framework of this project was the base of multiple internal projects. ISPyB is still being used across many synchrotrons in Europe
