Proven Success in Transformation
FinTech: Core Banking Re-architecture
Industry: Financial Services
Client Overview: A mid-sized regional bank was struggling with a 20-year-old COBOL-based core banking system. The system was a black box, making it incredibly slow and expensive to launch new digital products like mobile banking features or open banking APIs. They faced increasing pressure from agile FinTech startups and needed to innovate to survive.
"Developers.dev didn't just replace our old tech; they transformed our business. We're now launching features in weeks, not years. Their strategic approach to re-architecting was a game-changer for our competitive position."
Problem:
The monolithic mainframe system was a major bottleneck. It was unstable, lacked scalability during peak processing times, and the scarcity of COBOL developers made maintenance prohibitively expensive.
Key Challenges:
- Ensuring zero-downtime during the phased migration.
- Maintaining data consistency and integrity between the old and new systems.
- Meeting stringent financial regulatory and compliance requirements (e.g., PCI DSS, SOC 2).
- Retraining internal staff to manage a modern, cloud-native microservices architecture.
Our Solution:
We implemented a phased, strangler fig pattern approach to re-architect the monolith into a cloud-native application on AWS.
- Conducted an AI-assisted analysis to map dependencies and carve out business domains for microservices.
- Developed new services in Java/Spring Boot, containerized them with Docker, and orchestrated them with Kubernetes (EKS).
- Implemented event-driven architecture using Kafka for asynchronous communication between services.
- Built a robust CI/CD pipeline using Jenkins and Terraform to automate deployment and infrastructure management.
Healthcare: EMR Replatforming to Cloud
Industry: Healthcare
Client Overview: A large hospital network was running their Electronic Medical Record (EMR) system on-premise. The aging hardware was unreliable, expensive to maintain, and couldn't support modern demands for telemedicine or interoperability with other healthcare providers. They needed a secure, scalable, and HIPAA-compliant solution.
"The migration of our EMR system was a monumental task, and the Developers.dev team handled it with flawless execution. Their expertise in HIPAA compliance and Azure was evident at every step. Our physicians now have faster, more reliable access to patient data."
Problem:
The on-premise EMR was prone to outages, had slow response times, and couldn't scale to handle the influx of data from new clinics. Furthermore, sharing data with partner labs and clinics was a manual, insecure process.
Key Challenges:
- Ensuring strict adherence to HIPAA and HITECH regulations throughout the migration.
- Migrating petabytes of sensitive patient data (PHI) with zero data loss.
- Minimizing disruption to clinical workflows during the transition.
- Integrating the new cloud-based EMR with dozens of existing hospital systems (Labs, Radiology, Billing).
Our Solution:
We executed a lift-and-optimize replatforming of their EMR application to Microsoft Azure, focusing on security and reliability.
- Designed a HIPAA-compliant Azure environment using services like Azure Private Link, Key Vault, and Azure Security Center.
- Utilized Azure Database Migration Service for a secure and efficient transfer of their SQL Server databases.
- Containerized the application front-end and back-end components and deployed them to Azure App Service for scalability.
- Implemented Azure API Management to create a secure gateway for FHIR-based interoperability with third-party systems.
Retail: Monolith to Microservices Refactoring
Industry: E-commerce & Retail
Client Overview: A rapidly growing online fashion retailer's custom-built PHP monolith was buckling under pressure. Every small change required a full system deployment, leading to slow feature releases and frequent bugs. They couldn't innovate on features like personalized recommendations or dynamic pricing to compete with larger players.
"Our monolithic platform was killing our agility. Developers.dev's refactoring and re-architecting process was methodical and brilliant. We now have independent teams deploying new features daily. It's completely changed our ability to compete."
Problem:
The tightly-coupled architecture meant that the product, cart, and order systems were all intertwined. A bug in one area could bring down the entire site, especially during high-traffic sales events like Black Friday.
Key Challenges:
- Decomposing the massive PHP codebase into logical, independent services.
- Managing a complex data migration from a single MySQL database to multiple purpose-built databases.
- Building a culture of DevOps and independent team ownership.
- Maintaining a seamless customer experience during the gradual rollout of new services.
Our Solution:
We refactored the monolithic application into a set of containerized microservices hosted on Google Cloud Platform (GCP).
- Identified core business capabilities (Product Catalog, Inventory, Cart, Orders, Payments) and refactored them into separate Node.js services.
- Deployed the services to Google Kubernetes Engine (GKE) for automated scaling and management.
- Used a combination of databases: Cloud SQL for transactional data and Firestore for the product catalog to improve query performance.
- Implemented an API Gateway (Apigee) to manage and secure communication between the front-end and the new microservices.

Frequently Asked Questions
The first and most critical step is a comprehensive Assessment and Discovery phase. We use AI-powered tools and expert analysis to map your existing system's architecture, code quality, dependencies, and business logic. This data-driven approach allows us to create a detailed, low-risk modernization roadmap tailored to your specific business goals.
We employ several proven strategies to minimize disruption. For complex systems, we often use the "Strangler Fig" pattern, where we gradually build new services to replace old functionality, running both systems in parallel until the legacy system can be safely decommissioned. For simpler migrations, we use techniques like blue-green deployments to ensure a seamless cutover with instant rollback capabilities.
The right choice depends entirely on your goals and constraints:
- Replatform ("Lift and Optimize"): Best for quickly moving to the cloud to gain scalability and reliability with minimal code changes. It's faster and lower cost upfront.
- Refactor: Ideal when the core architecture is sound, but the code is inefficient or hard to maintain. It improves performance and reduces technical debt without a full rewrite.
- Re-architect: The most intensive approach, best when the fundamental monolithic architecture is limiting your business agility. This involves redesigning the system (e.g., into microservices) for maximum long-term flexibility and scalability.
Our initial assessment will provide a clear recommendation on the best path forward for your application.
Data security is our top priority, especially with sensitive information. We are ISO 27001 and SOC 2 certified. Our process involves creating secure data transfer pipelines (e.g., VPN, AWS Direct Connect), encrypting data both in transit and at rest, and performing multiple validation checks to ensure data integrity and completeness. We have extensive experience with compliance frameworks like HIPAA and PCI DSS.
Cost savings come from multiple areas. By moving to the cloud, you eliminate capital expenditures on hardware and reduce operational costs for maintenance and data center space. More importantly, a modernized, automated system drastically lowers the cost of change, reduces bug-fixing time, and accelerates feature delivery, leading to significant long-term ROI and improved developer productivity.
