Frequently Asked Questions

Key architectural, technological, and delivery insights regarding Guru Group's Digital Engineering Services.

We avoid high-risk "big-bang" rewrites. Instead, we implement the battle-tested Strangler Fig pattern. We begin by deploying an intelligent API gateway or proxy interceptor in front of the legacy application. As we design and deploy modern, containerized microservices, traffic for specific bounded contexts is incrementally rerouted to the new services. Database synchronization is maintained in real time using Change Data Capture (CDC) with tools like Debezium and Kafka, allowing legacy components to be safely retired without customer downtime.

Our technology choices are guided by performance, scalability, and maintainability. For frontend applications, we specialize in React, Next.js, and TypeScript, providing server-side rendering (SSR) and sub-second edge loading. On the backend, we implement .NET Core, Node.js (NestJS), Java Spring Boot, or Go (Golang) microservices deployed in Docker containers on Kubernetes (AKS/EKS), backed by managed relational (PostgreSQL) and distributed NoSQL/Redis databases.

The choice depends on specific hardware and latency requirements. For 85% of enterprise use cases, modern cross-platform frameworks like Flutter and React Native provide native-equivalent 60 FPS performance, single codebase velocity across iOS and Android, and 40% lower maintenance costs. For applications requiring intensive real-time hardware manipulation, specialized Bluetooth/BLE peripheral integration, or low-level OS enclaves, we engineer purely native Swift (iOS) and Kotlin (Android) apps.

We implement a defense-in-depth Zero-Trust API architecture. All endpoints are guarded behind centralized API Gateways (such as Azure API Management, Kong, or AWS API Gateway) with OAuth 2.0 / OpenID Connect (OIDC) authentication, JSON Web Token (JWT) signature verification, rate-limiting, and mutual TLS (mTLS) for inter-service communication. Furthermore, automated DevSecOps pipelines scan codebases for OWASP Top 10 API vulnerabilities prior to deployment.

Your enterprise retains 100% ownership of all source code, architectural schematics, CI/CD scripts, container configurations, and documentation produced. Guru Group operates on transparent, client-owned repository access (GitHub, GitLab, or Azure DevOps) with zero proprietary vendor lock-in or recurring software usage penalties.

We provide dedicated agile pods consisting of Solution Architects, Senior Full-Stack Developers, QA Automation Engineers, and DevOps Specialists. Discovery and MVP blueprints typically conclude in 2 to 4 weeks, followed by bi-weekly sprint deliveries. Production releases for standalone web/mobile apps or API middleware generally deploy within 3 to 6 months, while complex multi-phase legacy system migrations run on structured milestone schedules.
