Telecom CRM and Self Service

From 2015–2019 I worked on Swiss telco Sales and Self‑Service applications: Angular WebApps for SME and retail customers backed by an OpenShift/Oracle micro‑services platform. The scope covered Software‑Defined networking for SMEs (order, configure, change) and retail sales & ordering tools used by customers and internal sales channels.

• Angular front‑end suite (multi‑app) for sales journeys and self‑service
• OpenShift‑hosted micro‑services with Oracle middleware/DB integrations
• CRM, provisioning and billing integration; SSO and role‑based access

The programmes ran in a regulated, high‑availability environment with zero‑downtime objectives. We delivered incrementally: feature‑flagged rollouts, strong API contracts and close alignment with design system guidelines.

• Incremental delivery with canary/staged releases and rollback paths
• API gateway integration and schema‑validated service contracts
• Design system compliant components and accessible flows
• Monitoring, tracing and meaningful product telemetry

I contributed across the sales funnel and self‑service lifecycle: from product selection and eligibility to ordering, provisioning and post‑sales changes for Software‑Defined SME networking.

• Sales & Eligibility: Guided sales flows, address checks, options/pricing, quote creation
• Ordering: Robust forms, validation, and order orchestration with idempotent retries
• Self‑Service: Configuration changes, upgrades and incident flows with clear SLA feedback

We built Angular applications that integrate with OpenShift‑based micro‑services (REST/gRPC) and Oracle systems. The architecture emphasised loose coupling and resilience.

• Angular/WebApps: Shared component library, route‑level code‑splitting, SSR where needed
• Platform: OpenShift, API gateway, OAuth/SSO, Oracle middleware & DB
• Quality: Contract tests, E2E tests, synthetic monitoring, structured logging and tracing
