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.
Tech stack:
- Infrastructure as Code: Terraform, AWS CDK, Ansible.
- Containers: Kubernetes on EKS, AKS, Docker.
- Streaming Data Processing: Kafka to Confluent Cloud, after AWS MSK.
- Frontend: TypeScript, React, NextJS, Hooks, Styled Components.

About the technology
Cloud database foundation
MongoDB Atlas is the fully managed cloud service for MongoDB databases. It handles provisioning, backups, monitoring, upgrades and security controls while teams work with a document model built for changing application data. Companies use it for web and mobile products, APIs, event-driven services, content platforms and data-intensive business applications.
Data and application design
Strong Atlas work starts with a sound document model. Specialists plan collections, embedding and referencing, indexes, validation rules and aggregation pipelines around real access patterns. They connect Atlas with application frameworks, serverless functions, message streams and analytics services without losing control of consistency or operational cost.
- Model documents for application read and write patterns
- Build aggregation pipelines and performance-focused indexes
- Connect services through drivers, APIs and event integrations
- Prepare migrations from relational or self-managed MongoDB systems
Atlas ecosystem
The service includes features such as Atlas Search, Vector Search, Charts, Data Federation, Online Archive and Stream Processing. Professionals may also work with MongoDB Compass, the Atlas CLI, Terraform, Kubernetes operators and observability tools. Related expertise in Node.js, Java, Python, TypeScript, cloud networking and CI/CD often matters to the delivery.
When companies need specialists
Freelance expertise is useful when a product is moving from prototype to production, when a legacy database needs migration or when an existing cluster shows performance and reliability problems. Companies also bring in specialists for multi-region design, access control, disaster recovery, search, vector workloads and infrastructure automation.
- Review slow queries, indexes and workload patterns
- Establish private networking, roles, encryption and auditing
- Plan resilient clusters and tested backup recovery
- Automate Atlas environments with infrastructure as code
Collaboration in Germany
Teams in Germany may need an expert for a focused migration, a longer product engagement or support across several time zones. Remote collaboration works well when documentation, access boundaries and incident procedures are clear; on-site workshops can help with architecture decisions and handover. German or English communication should match the project team and stakeholders.
What good work looks like
A capable MongoDB Atlas professional explains trade-offs instead of treating the document model as a default answer. They test queries with representative data, define measurable service objectives, protect credentials and document operational runbooks. Quality also shows in repeatable deployments, realistic recovery tests and a clear plan for scaling search, transactions or analytics workloads.
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 customer-facing applications, APIs, content systems, real-time services, search experiences and workloads that benefit from flexible document data.
MongoDB Atlas uses a document model with rich queries and aggregation, while DynamoDB is a more narrowly optimized key-value and document service. Compared with managed SQL, Atlas can simplify data that naturally belongs together in documents, but relational systems may be stronger where joins, strict schemas or complex transactional reporting dominate.
A strong MongoDB Atlas specialist should understand at least one application language and its MongoDB driver, plus cloud networking, identity management, backups and observability. Experience with Terraform, Kubernetes, CI/CD, Atlas Search or data migration is valuable when the engagement extends beyond basic database setup.
The right level depends on the risk and scope of the work. A contained schema review may need focused Atlas expertise, while a migration, multi-region rollout or recovery redesign calls for someone who has operated comparable production workloads and can validate decisions with tests.
Yes, MongoDB Atlas work is well suited to remote collaboration because configuration, reviews and documentation can be handled securely online. Teams should define access controls, meeting times, incident ownership and language expectations; on-site sessions can still help with workshops or sensitive handovers.
Ask the MongoDB Atlas specialist to explain the data model, query patterns, index choices, failure assumptions and recovery process in concrete terms. Review infrastructure code, security settings, monitoring dashboards and test evidence rather than relying only on a successful deployment.
MongoDB Atlas Search is useful when application data and search indexes should be managed close together with relevance controls and filtering. Atlas Vector Search fits semantic retrieval and AI-assisted experiences, but the specialist should first assess embedding quality, freshness, latency, access rules and the need for a separate search system.
Freelancers working with MongoDB Atlas often handle schema design, migrations, performance tuning, security reviews, Terraform automation and production readiness. They may also deliver Atlas Search, Vector Search, event-driven integrations, monitoring and runbooks for teams that need practical operational ownership.
