Building robust web applications means confronting and solving challenges at every layer — from architecture and testing to performance and design. At WalkingTree Technologies, we don’t just code. We engineer resilient, scalable, and secure web apps with precision.
Here’s how we approach the most critical engineering challenges in modern web development:
1. Code Quality & Reliability
The Challenge:
In large or fast-growing web apps, maintaining consistent code quality often leads to tech debt and regression issues
Our Solution:
We adopt Test-Driven Development (TDD) and integrate unit tests directly into CI/CD pipelines. This ensures bug-resistant, modular code. We also enforce code coverage metrics to validate each build before deployment.
2. Complex Integration Testing
The Challenge:
Integrating APIs, databases, and third-party services can create fragile dependencies and hard-to-diagnose failures during testing.
Our Solution:
We use mocking frameworks and dependency injection to isolate integration points and simulate external systems. This significantly reduces execution time and improves test coverage and reliability.
3. Choosing the Right Tech Stack
The Problem
Choosing technologies without understanding business workflows often leads to misaligned architectures and rework.
Our Solution:
We create High-Level and Low-Level Design documents and conduct reverse knowledge transfer sessions to ensure that technical decisions are fully aligned with business goals and domain workflows.
4. Application Security
The Challenge:
Modern web apps are prime targets for unauthorized access, data leaks, and security breaches.
Our Solution:
We implement Keycloak for authentication and access control, and enforce AES-256 and TLS 1.3 for encryption. We also conduct regular code audits with SonarQube to detect and fix vulnerabilities early.
5. Scalability & Performance Optimization
The Challenge:
As user traffic grows, poorly optimized apps can experience latency, downtime, and resource exhaustion.
Our Solution:
We optimize PostgreSQL indexing (GIN, BRIN, composite), apply caching via Redis and CDNs, and deploy using Docker + Kubernetes for containerized, horizontally scalable infrastructure.
6. Responsive UI Across Devices
The Challenge:
Inconsistent user experience across screen sizes can reduce usability and accessibility.
Our Solution:
Using Angular Flex Layout, CSS Grid, and media queries, we design fully responsive interfaces. Cross-device testing with BrowserStack ensures seamless experience across desktops, tablets, and mobiles.
7. API Management & Documentation
The Challenge:
Poorly documented or unsecured APIs create bottlenecks for frontend teams and integration partners.
Our Solution:
We follow RESTful design principles with versioning, secure APIs using OAuth2 and JWT, and document everything using Swagger/OpenAPI for clarity and ease of collaboration.
8. Database Migration & Query Optimization
The Challenge:
Manual schema changes and unoptimized queries can lead to downtime and performance bottlenecks.
Our Solution:
We use Flyway for version-controlled schema migrations, optimize queries with batching and indexing, and manage database connections with HikariCP in Spring Boot environments.
9. UX and Design Consistency
The Challenge:
Clunky interfaces and confusing user flows reduce engagement and conversion.
Our Solution:
We craft intuitive UIs using Angular, React, or Vue, embed tooltips, onboarding flows, and validate designs with A/B testing, heatmaps, and accessibility audits to ensure user delight.
10. Post-Launch Support & Maintenance
The Challenge:
Without structured support, post-deployment issues can disrupt user experience and delay fixes.
Our Solution:
We offer 24×7 SLA-driven support, maintain detailed documentation for handovers, and drive continuous improvement using user feedback and real-time analytics.
