Client Overview
FinSecure Capital is a mid-sized wealth management firm struggling with a monolithic legacy platform. The system was slow, difficult to update, and couldn't handle peak trading volumes, leading to customer complaints and missed opportunities.
The Problem
The client needed to modernize their core trading and portfolio management platform without disrupting existing operations. The goal was to improve performance, enhance security, enable faster feature rollouts, and reduce their ballooning infrastructure costs.
Key Challenges:
- Migrating a complex, monolithic application to a microservices architecture.
- Ensuring zero-downtime during the transition.
- Meeting strict financial industry compliance and security standards.
- Integrating with multiple third-party financial data providers.
Our Solution:
We implemented a phased approach to decompose the monolith into scalable, independent microservices, deployed on a Kubernetes cluster in AWS.
- Technology Used: Go for backend services, React for the frontend, PostgreSQL, Kafka for event streaming, Kubernetes, and Terraform for IaC.
- Agile Pods: Deployed a dedicated pod of 6 engineers, including a solution architect and a DevOps specialist.
- CI/CD Implementation: Built a robust CI/CD pipeline using Jenkins and ArgoCD for automated testing and deployment, reducing release cycles from months to days.
- Security First: Integrated advanced security scanning tools into the pipeline and implemented a service mesh for secure inter-service communication.
Client Overview
HealthFirst Clinics, a regional network of healthcare providers, needed a centralized, secure, and user-friendly patient portal to improve patient communication, streamline appointment scheduling, and provide access to medical records.
The Problem
Their existing system was a patchwork of outdated tools, leading to a fragmented patient experience and administrative inefficiencies. They required a unified platform that was fully HIPAA compliant, integrated with their existing Electronic Health Record (EHR) system, and accessible on both web and mobile.
Key Challenges:
- Ensuring strict adherence to HIPAA regulations for data privacy and security.
- Complex integration with a legacy EHR system via HL7/FHIR protocols.
- Designing an intuitive interface for a non-technical user base of varying ages.
- Building a scalable solution to support a growing number of patients and clinics.
Our Solution:
We designed and developed a cloud-native patient portal with a responsive web interface and native mobile apps for iOS and Android.
- Technology Used: .NET Core for the secure backend API, Angular for the web portal, Swift (iOS) and Kotlin (Android) for mobile, and Azure for hosting with HIPAA-compliant services.
- EHR Integration: Built a custom integration layer to securely communicate with the client's on-premise EHR system.
- User-Centric Design: Conducted extensive UX research to create a simple, accessible interface for appointment booking, prescription refills, and viewing lab results.
- Compliance & Security: Implemented end-to-end encryption, multi-factor authentication, and regular security audits to ensure data integrity and compliance.
Client Overview
StyleHive is a fast-growing online fashion retailer built on Magento. Their platform struggled to handle traffic surges during sales events, resulting in slow load times, cart abandonment, and significant revenue loss.
The Problem
The client's monolithic Magento architecture and under-provisioned hosting could not keep up with their growth. They needed a solution that would improve site performance, scale automatically to handle traffic spikes, and enhance the overall customer experience to boost conversions.
Key Challenges:
- Optimizing a feature-rich but slow Magento 2 application.
- Designing a cloud infrastructure that could scale on-demand without being cost-prohibitive.
- Minimizing downtime during the migration to the new infrastructure.
- Integrating a headless CMS for faster content updates.
Our Solution:
We executed a "lift and shift" of their Magento application to AWS, followed by a systematic performance optimization and decoupling of the frontend.
- Technology Used: Magento 2, AWS (EC2 Auto Scaling, RDS, ElastiCache for Redis), Cloudflare CDN, Varnish Cache, and a headless approach using Contentful.
- Infrastructure as Code: Used Terraform to define and manage the entire cloud infrastructure, enabling repeatable and reliable environments.
- Performance Tuning: Conducted extensive performance profiling and optimized database queries, implemented advanced caching strategies, and configured a CDN to serve assets globally.
- Headless Architecture: Decoupled the frontend from the Magento backend, allowing for a faster, more flexible user experience built with React and enabling the marketing team to manage content independently.
