Principal Cloud DevOps Architect at BP
In my role as Senior Cloud DevOps Architect for BP, an oil and gas company, I had the mission to migrate the Electric Vehicle Charging platform of the EV Division from on-premises and Azure to AWS cloud, resulting in a hybrid multi-cloud, multi-tenant SaaS solution.
Deployment with Kubernetes for the application layer meant provisioning Kubernetes clusters managed by EKS and AKS, with a focus on integrating them into a multi-tenant environment. This integration was achieved by using Kubernetes namespaces and access controls to ensure data isolation and privacy enforcement.
In the database layer, we chose an RDS instance with PostgreSQL to support the backend infrastructure of our applications. Tenants shared the same RDS instance, but each had a dedicated schema.
To ingest near real-time data from physical charge points (CPOs), as IoT devices, via the OCPI protocol, we ran into significant delays with batch processing. As a result, we built a real-time streaming data pipeline using Apache Kafka, while prioritizing an event-driven architecture.
Led collaboration across multiple internal teams, external vendors, cloud providers, and on-site partners to integrate over five systems into a unified solution.
Achievements:
- Successfully designed and implemented hybrid multi-cloud solutions, integrating multiple cloud platforms (AWS, Azure) with on-premises infrastructure, using Site-to-Site VPNs, Firewalls, and Load Balancing.
- Led the migration of on-premises infrastructure to multi-cloud, multi-tenant infrastructure, resulting in 30% faster processing times.
- Migrated workloads from VMware and Hyper-V environments to cloud-based VMs, leveraging cloud-native services to optimize performance, cost efficiency, and scalability.
- Designed a multi-tenant Kubernetes platform leveraging the Kubernetes ecosystem, using Karpenter for dynamic EC2 node provisioning, KEDA for event-driven pod autoscaling (e.g., Kafka message lag), and Rancher for centralized monitoring of multiple clusters (EKS, AKS, or on-prem K8s), replacing Microsoft-centric Azure Arc management service.
- Designed and implemented Python-based FastAPI microservices as part of the EV core-backend on AWS EKS application layer, powering data ingestion and customer analytics pipelines.
- Developed asynchronous, event-driven APIs (Python-FastAPI) for real-time integration with CPOs, supporting OCPI 2.3 and OICP protocols.
- Designed and implemented a secure, production-grade Azure Databricks platform using Terraform, ensuring scalability and cost efficiency.
- Migrated on-premises ERP to a hybrid Dynamics 365 architecture with ERP hosted locally and CRM running in Azure, integrated via Azure Arc.
- Automated CI/CD pipelines for Databricks notebooks and jobs using GitHub Actions & Databricks CLI, reducing deployment time. Reduced infrastructure provisioning time by 70% by automating cloud resource deployment with GitOps.
- Ensured compliance with internal audit and data governance standards (GDPR) through OAuth2/OIDC-based authentication and fine-grained role-based access controls.
- Developed a Zero Trust security model, enforcing least-privilege access and microsegmentation, enhancing security posture and compliance with GDPR and NIST.
- Built interactive analytics dashboards in Amazon QuickSight, integrating data from S3 and Redshift to deliver real-time business insights and visualizations with embedded access for multi-tenant users.
- Led cloud security assessments and full-lifecycle cybersecurity integration during M&A, covering AWS, Azure, IAM (Entra ID), and data protection, while aligning security posture with NIST, ISO 27001, and GDPR across hybrid and cloud-native environments.
- Reduced cloud costs by 64% for a client's dev environment by implementing automated start/stop schedules for EC2 and RDS instances via AWS CDK with EventBridge Scheduler or AWS Systems Manager.

About the technology
Document database
MongoDB Atlas is the managed cloud service for MongoDB, a document database built around flexible BSON documents rather than relational tables and rows. Companies use it for customer platforms, product catalogues, content systems, event data and APIs that need to evolve without constant schema migrations. Atlas runs the database infrastructure while teams focus on application data and delivery.
Atlas foundations
Atlas specialists plan clusters, regions, replication and workload isolation around application needs. They configure the MongoDB Query API, indexes, aggregation pipelines, transactions and change streams, then connect services with official drivers or frameworks such as Node.js, Java, Python and .NET. Strong work also covers schema validation, data lifecycle policies and backup design.
Search and services
Atlas extends beyond core storage with tools for search, analytics and application integration. Specialists may deliver Atlas Search indexes, vector search for retrieval use cases, Data Federation, Charts or App Services, depending on the solution. They also work with Kubernetes, Terraform, CI/CD pipelines, observability tools and cloud services across AWS, Azure or Google Cloud.
When to bring help
Companies often need focused expertise when an existing MongoDB deployment moves to Atlas, a new product requires a flexible data model, or production queries become difficult to operate. Freelance specialists can support:
- Cluster sizing, migration and cutover planning
- Schema, index and aggregation design
- Access control, encryption and backup policies
- Atlas Search or vector search implementation
- Performance checks and operational handover
Germany delivery
Teams in Germany may engage Atlas professionals for a defined migration, a longer product build or an operational review. Remote collaboration works well when documentation, access procedures and release ownership are clear; on-site workshops can help with architecture decisions and stakeholder alignment. German and English communication requirements should be agreed at the start.
What quality looks like
A strong MongoDB Atlas professional connects database choices to application behavior, not just console settings. They explain why a document model, index or consistency option fits the workload, test failure scenarios and leave clear runbooks. Look for evidence of production migrations, secure cloud operations, measurable query diagnosis and thoughtful collaboration with application and infrastructure teams.
Frequently asked questions
What clients ask us most about MongoDB Atlas — answered in short.
MongoDB Atlas is used to run managed MongoDB databases in the cloud. Companies use it for APIs, customer applications, catalogues, content platforms, event data and search experiences that benefit from document-oriented storage and flexible data models.
MongoDB Atlas provides managed provisioning, backups, monitoring, scaling options and security controls, while a self-managed MongoDB deployment leaves those responsibilities with the company. The right choice depends on compliance needs, infrastructure capability, network design and the level of operational control required.
MongoDB Atlas can suit rapidly changing document structures, nested data and high-volume application workloads. PostgreSQL may be a better fit for strongly relational data, complex joins or teams that depend heavily on mature SQL features; a specialist should assess access patterns rather than choose from database labels alone.
MongoDB Atlas work often requires cloud networking, IAM, Terraform, Kubernetes, CI/CD and observability knowledge. Application experience with Node.js, Java, Python or .NET is also valuable because data modeling and query performance must reflect how services actually read and write data.
MongoDB Atlas projects need different levels of experience depending on the work. A focused schema or query review can be handled by a specialist familiar with the application, while migrations, sharding, multi-region design or production security require a professional who has operated comparable systems under real workload conditions.
MongoDB Atlas is well suited to remote delivery because configuration, documentation and review can be handled through shared repositories and controlled cloud access. German companies should clarify data access, working hours, security approvals and whether German-language communication is needed; on-site sessions can be reserved for workshops or critical cutovers.
MongoDB Atlas expertise is best assessed through concrete decisions and outcomes, not a list of certifications. Ask how the professional would model the data, select indexes, handle backups and test failover, then request examples of production diagnosis, migration planning and operational documentation.
MongoDB Atlas specialists may deliver a target architecture, data model, migration plan, cluster configuration, access policies, indexes, aggregation queries and monitoring dashboards. Depending on scope, they can also implement Atlas Search, connect application drivers, automate infrastructure and prepare runbooks for the internal team.
