Software Engineer with experience co-designing and evolving complex, multi-brand web platforms. Strong focus on frontend architecture, platform collaboration and scalable, maintainable systems in regulated environments. A decade of experience working on production systems.

Senior Frontend Engineer at tb.lx (Daimler Truck) (2021-01 – Present)

• Co-designed and developed a TypeScript SDK, working closely with the Principal Frontend Engineer, enabling third-party portals (React / Node.js) to integrate internal services.
• Designed integration layers supporting GraphQL, REST and SSE, including an authentication proxy abstracting internal infrastructure and security constraints.
• Acted as co-owner of the SDK until ownership was successfully transferred to an external business partner.
• Co-designed and implemented the frontend architecture for a Next.js multi-brand web platform.
• Monorepo structure separating deployable apps from shared packages (services, business logic, UI components, templates, design system).
• Independent versioning and deployments per brand and feature set.
• Custom MUI-based design system, supporting multiple brands and Middle Eastern markets.
• Partnered with Platform teams on CI/CD and delivery standards, contributing Dockerfiles and Helm charts.
• Defined state management strategies using Apollo Client, Redux, component-local state and React Context.
• Contributed to observability and operational readiness using Prometheus, Grafana, Azure logs and PagerDuty.
• Integrated OIDC authentication and collaborated on GDPR compliance, user-centric data and consent flows.
• Delivered a web application enabling route feasibility simulations for electric trucks, supporting commercial teams in evaluating real-world operational scenarios.
• Released a public-facing version of the platform with a reduced feature set, complementing internal tooling.
• Despite being a niche product, the platform consistently handled on the order of a few thousand simulations per month, demonstrating sustained real-world usage.
• Accelerated frontend delivery and platform consistency through the introduction of a scalable MUI-based design system.
• Lowered the barrier for full-stack and backend engineers to contribute to frontend development.
• Abstracted UI complexity while improving maintainability and cross-brand consistency.
• Increased leverage of AI-assisted development by relying on widely adopted, well-documented component patterns.
• Reduced technical and regulatory risk by defining durable frontend architecture boundaries and compliant authentication and data-handling flows.
• Partnered with the Product Manager to translate GDPR and legal requirements into technical decisions, aligning legal, product and engineering concerns.
• The platform was later recognized internally within Daimler Truck for its contribution to electric mobility initiatives, validating the long-term value and resilience of the solution.

Full-Stack Engineer - Telecom, Public Sector & Enterprise Systems at Celfocus · Bee Engineering · Novabase · Galp Energia · LetShare (2015-01 – 2021-01)

• Worked on large-scale enterprise and telecom platforms, contributing across frontend and backend layers.
• Maintained and evolved legacy systems, focusing on stability, correctness and incremental improvements.
• Developed and integrated Java-based backends (Java EE, Spring) backed by relational databases.
• Built and maintained frontend components using early SPA patterns and server-side templating.
• Gained hands-on experience with enterprise authentication, CI/CD pipelines and application servers.
