Lead solution architecture for the migration of Telenor Norway's legacy on-premises billing platform to an Oracle Cloud-based Oracle BRM (OBRM) solution, translating current-state applications, dependencies, data flows, and non-functional requirements into a phased target-state design. Run discovery workshops with customer stakeholders to map business processes, upstream and downstream integrations, batch and real-time interfaces, data ownership, security requirements, operational constraints, and migration risks. Create the migration blueprint covering phased workload transition, temporary coexistence between legacy and cloud platforms, integration sequencing, cutover criteria, rollback planning, reconciliation, and post-migration hypercare. Address data and integration challenges by defining source-to-target mappings, validation and reconciliation controls, exception handling, API and adapter boundaries, contract testing, and parallel-run checkpoints to protect continuity and data integrity. Partner with customer architects and Oracle product, sales, and delivery teams to communicate solution value, resolve objections around cost, performance, resiliency, security, migration risk, and supportability, feed customer gaps into product discussions, and build alignment around the architecture roadmap. Design the target architecture across microservices, REST APIs, event messaging, distributed caching, databases, Kubernetes/OpenShift workloads, security controls, observability, and downstream enterprise integrations. Architect and deliver a highly available, low-latency platform serving more than 90M users and processing workloads up to 100K TPS with sub-second response requirements. Diagnose performance bottlenecks across application flows, cache lookups, and database interactions, reducing transaction latency by approximately 30%; lead architecture reviews and production-readiness decisions across customer and engineering teams.

As Lead Engineer, led the architecture and delivery of an AWS-hosted taxation microservice for a Prodapt client, replacing a tightly coupled on-premises tax function with an independently deployable cloud service. Defined service boundaries, API contracts, data flows, validation and error-handling patterns, security, deployment, and observability requirements; guided the engineering team through implementation, code reviews, testing, and release readiness.
