Project history
Defining and communicating the technical vision and engineering roadmap aligned with business goals. Leading hiring, onboarding, and mentoring while growing an engineering culture focused on quality and delivery. Driving architecture decisions for scalable, maintainable systems. Owning engineering processes including sprint planning, code review standards, QA automation, CI/CD, and release management. Implementing and evolving CI/CD pipelines, automated testing, and release orchestration. Introducing observability (logging, metrics, tracing). Actively contributing to the codebase with feature development, bug fixes, and refactors. Performing code reviews and mentoring engineers through PR feedback and pair-programming.
Architected and developed iOS applications using Swift, Xamarin (C#), and Flutter (Dart). Publication and maintenance of high-impact iOS applications. Gathering and analysing business requirements, meeting clients, and understanding workload and work plans. Involved in low-level and high-level design reviews for developing applications. Optimised delivery cycles by implementing continuous integration and continuous delivery pipelines for iOS.
Led the development of an enterprise-grade iOS application for the healthcare industry, prioritising strict data privacy compliance, high-performance UI, and accessibility for clinical users. Consulted on complex technical challenges, aligning development opportunities with business requirements and stakeholder needs. Automated the application development and release process, significantly improving team efficiency.
