London

* Drove the development of the Group Access Service integrating audio descriptions and closed captions with video content, to comply with Ofcom regulations.* Built an AWS Lambda-based Export Service to automate asset transfer and transcoding based onprovider-specific rules, simplifying the integration of multiple legacy services.* Maintained a Terraform provider for SDVI Rally, that enabled multiple deployments of the same supply chain and their AWS resources. This tool was adopted by multiple teams and became the standard tool for deployment in the company.* Delivered a transition from Rally’s FFmpeg provider to AWS Elastic MediaConvert for audio sidecarprocessing, reducing the cost of trancoding by more than 90%

London, England, United Kingdom

*Developed and deployed a Java and Kubernetes-based microservices system, called VTP. The project reduced video processing time by automating transcoding, validation, packaging and distributing steps.* Worked on Jensen, a Java/Kubernetes job-based microservice for routing and adopting notificationsacross multiple subsystems.* Transformed a legacy video packaging system by converting Bash scripts to Groovy-based, object-oriented scripts, achieving a >95% unit-tested solution that improved code maintainability and reduced implementation errors.* Designed and implemented a workflow in SDVI Rally to automate and streamline ad ingestion between different vendors.* Led the development of ComponentQC, a multi-step validation service (metadata, automatic, manual) to automate video quality control, reducing manual validation time.

Isleworth, England, United Kingdom

Hungary

* Developed a Python-based neural network standardization project, with initial applications detecting lung anomalies from X-rays.* Implemented an OAuth2 and OpenID Connect-based authentication and authorization system using WSO2, integrating with multiple identity providers via SCIM 2.0 to enhance interoperability across healthcare applications.

Hungary

* Designed, implemented, and tested update procedures for an OpenStack-based virtualization platform, utilizing Puppet and Ansible, which reduced downtime during update.* Supported the security team in hardening OpenStack by fine-tuning auditing features and by conducting code reviews on internal developments, enforcing secure coding standards.* Engineered a KVM snapshot and Docker-based testing system to enable Ansible script unit testing, reducing module testing time from hours to minutes by allowing isolated, rapid testing of individual components.

Hungary

* Programmed a Java-based client-server application for legal professionals to search Hungarian laws by ID and track historical changes, enabling side-by-side comparison of different law revisions* Led the transition from proprietary systems to open-source alternatives for critical services including firewall, VoIP PBX, email, file sharing, which enabled extending the infrastructure* Extended the infrastructure with a more reliable VPN solution and intrusion detection* Built a least-cost routing module for Asterisk PBX, optimizing caller ID mapping to minimize outbound call expenses and ensure callbacks were routed back to the original initiator, resulting in significant reductions in phone bills.
