Senior Software Engineer at Expian UK

January 1, 2023 - December 31, 2025

Spearheaded the architectural design and implementation of a high-throughput, event-driven ticketing platform on AWS, enabling processing of 5,000+ ticket generations per second and supporting scalable B2B/B2B2C SaaS operations. Engineered and launched a new component-based Single Page Application (Vite, React, Valtio), improving frontend performance, load time reduction and enhancing user experience for key B2B clients. Extended the current architecture of 5+ core microservices using Node.js and TypeScript, adhering to API-first design principles, which decoupled system components and improved development velocity by ~15%. Optimised AWS infrastructure (Lambda, SQS, SNS, DynamoDB) for the event-driven system, resulting in a ~20% reduction in processing latency and ~10% decrease in operational costs. Collaborated cross-functionally with product and QA teams to define requirements and ensure timely delivery of features in a fast-paced Agile (Scrum) environment, effectively communicating

Senior Software Engineer at HelviX

January 1, 2022 - December 31, 2023

Architected and developed a Vue.js SPA (VueX, Atomic Design) for a steel industry management platform, improving initial feature delivery time by 20% through a modular, DDD-informed design tailored for German steel companies. Engineered 3 critical microservices (Node.js, Serverless Framework, AWS) and deployed on AWS, enhancing system scalability to support 1,000+ concurrent operations for enterprise clients. Implemented targeted performance optimisations for the SPA, achieving a 30% improvement in Lighthouse scores and a 15% reduction in user-reported latency. Championed Domain-Driven Design (DDD) principles across the development team, leading to a more robust and maintainable codebase and facilitating easier integration of new modules.
