Enabling Digital Services, IT Infrastructure, and Data Management in the Public Sector

• Designed and led migration from monolith to microservices using Java SpringBoot, improving system scalability and team autonomy.
• Architected event-driven inter-service communication with Apache Kafka for high-throughput asynchronous data streams.
• Implemented CQRS pattern across core services to optimize query performance and enable independent scaling of read/write workloads.
• Engineered gRPC-based inter-service communication, reducing internal API latency by ~40% vs. REST.
• Improved API Gateway layer covering authentication, rate limiting, load balancing, and request routing for all microservices.
• Integrated Redis for dispense caching and session management, reducing database load by ~60% and improving response times.
• Built full-stack features with Next.js, React, TypeScript (frontend) and Node.js/Express.js alongside Spring Boot (backend).
• Enhanced real-time geospatial dashboards with ArcGIS.js, integrating live Kafka data streams into interactive map visualizations.
• Established team-wide engineering standards: code review guidelines, TypeScript conventions, API design principles, and microservices best practices.
• Mentored 4+ mid-level and junior engineers through 1-on-1s, pair programming, and architecture walkthroughs.
• Led incident response and post-mortem processes; improved observability via structured logging, distributed tracing, and alerting pipelines.
• Collaborated with product and business stakeholders to translate requirements into technical roadmaps and delivery milestones.

Enabling Digital Services, IT Infrastructure, and Data Management in the Public Sector

• Architected and delivered scalable full-stack applications with Next.js, React, Node.js, and Express.js, owning features from design to production.
• Leveraged Next.js SSR, SSG, and ISR to optimize page performance, improve SEO scores, and reduce initial load times significantly.
• Migrated JavaScript codebase to TypeScript across frontend and backend, reducing runtime errors by ~30% and improving developer experience.
• Built complex geospatial mapping solutions with ArcGIS.js: custom map layers, spatial queries, and real-time data overlays.
• Designed Next.js API routes alongside Express.js services to create a unified, type-safe backend layer with full TypeScript coverage.
• Optimized application performance through dynamic imports, image optimization, edge caching, and route-level code splitting.
• Conducted code reviews for junior developers, enforcing TypeScript best practices, clean architecture, and Next.js conventions.
• Collaborated in agile sprints, consistently delivering features on time with well-tested, maintainable code.
