Features localized Trivia, Logo Trivia, Fibbage (social deception), and Doodle Guess. Validated with over 2,500 unique sessions on launch weekend, 408 matches, an 88.2% completion retention rate, and featured on ProTV iLikeIT.
Bafta Media Network (Digital Signage)
2026 In-HouseSmart digital signage platform empowering venues (restaurants, pubs, bars, clinics) to publish and manage promotional content on their screens in real time directly from their smartphones, alongside curated educational and entertainment streams managed by our network. Architected with Android TV Kiosks, Node.js backend, real-time WebSockets, PostgreSQL, React, and Astro.
Engineered a smart automation system using Java 20, Spring Boot, and Python that dynamically orchestrates Ansible playbooks across 100+ complex steps for large-scale ExaCC database manipulations and migrations. Designed automated certification pipelines utilizing Python, Jenkins, and Automic, streamlining database patching on Oracle Cloud Infrastructure (OCI) and OpenShift. Required regular monthly on-site travel to Frankfurt, Germany.
Architected and delivered backend microservices for a private grain commodities market and livestock order tracking system (Java, Spring Boot, PostgreSQL, Twilio). Built real-time chat and trading microservices from scratch using Node.js, Socket.io, Kafka, and MongoDB on AWS (EKS, RDS, CloudFront).
Deloitte Digital | UK Retail Tier-1
Maintained and scaled 10+ core microservices for a massive UK retailer using Java, Kotlin, and Spring Boot. Orchestrated resilient microservices on Google Cloud Platform (GCP) and Kubernetes, leveraging Google Pub/Sub, Prometheus, and Grafana for monthly seamless release cycles.
Co-founded an Industry 4.0 augmented reality startup, leading a team of 5 developers to build the complete product ecosystem through 5 hardware generations: from early Raspberry Pi prototypes to custom PCBs and native Android smart glasses with thermal vision, continuous QR scanning, MQTT, WebRTC, I2C, and scalable AWS cloud backend.
IDEMIA (Ausy | IDEMIA)
Engineered and deployed critical software updates and customizations for biometric security products utilized directly by international police departments in advanced forensics flows. Customized and scaled enterprise Java and JBoss applications for IDEMIA, collaborating with cross-functional teams across France, the Netherlands, Romania, and Serbia. Authored advanced utility tools, custom log parsers, and reporting pipelines for high-stakes production environments.
