Introduction:
In today’s fast-paced digital world, seamless connectivity is crucial for businesses to succeed. As an API Integration Developer, I’ve had the opportunity to work with powerful technologies like Kong Gateway and Apigee, helping businesses improve performance, streamline operations, and foster innovation.

Did you know that APIs are responsible for over 90% of digital business strategies? This highlights just how important it is to have the right API management in place. In this post, I’ll share my journey and the lessons I’ve learned in optimizing API ecosystems for businesses.

The API Landscape: Why Integration Matters

APIs (Application Programming Interfaces) enable different systems to communicate and collaborate effectively. Efficient API management is crucial, and this is where API gateways like Kong and Apigee play a vital role. These tools assist businesses by providing:

Easy Integration: Seamlessly connecting various systems and services.
Enhanced Security: Protecting APIs with robust security policies and threat detection mechanisms.
Scalability: Managing high volumes of traffic without compromising performance.
Performance Monitoring: Ensuring APIs deliver optimal performance and an excellent user experience.

For instance, a banking company that processes thousands of transactions per second depends on effective API management to maintain smooth operations.

My Expertise in API Integration

Over the past two years, I've worked extensively in API integration, gaining hands-on experience with Kong Gateway and Apigee. Here's a look at my journey and the skills I bring to the table:

1. Migrating APIs from Apigee to Kong

One of my key projects was migrating over 100 APIs from Apigee to Kong, ensuring no downtime and a smooth transition. I used Kong’s advanced features to improve security, performance, and scalability, including:

Plugins: I integrated plugins like OAuth for authentication, rate limiting, and request transformations to make APIs safer and faster.
I extensively used plugins and features such as OAuth, Key-Auth, Request Transformer Advanced, ACL, Post-Function and Pre-Function (for Lua scripting), Route Transformer Advanced, Proxy-Cache, OAS Validation, Exit Transformer, IP-Restriction, Basic Auth, Request Validator, CORS, Response Transformer Advanced, Prometheus (at a global level), File-Log, OpenTelemetry, and Request Termination.
Lua Scripting: By leveraging Lua scripting in Kong, I streamlined API data manipulation and enhanced performance by efficiently handling backend interactions, dynamically modifying URLs with authorization tokens, and seamlessly managing error handling. Furthermore, I implemented robust signature generation logic in Lua to ensure secure and authenticated API requests, facilitating smooth integration and optimized API operations
API Management: Kong helped us efficiently manage our APIs, providing robust tools to monitor performance, optimize routing, and ensure seamless operation. Its plugin ecosystem allowed us to enhance security, enforce policies, and streamline API workflows, while detailed analytics empowered us to track usage trends and make data-driven decisions. By integrating Kong, we significantly improved scalability, reliability, and overall API lifecycle management.

This migration not only enhanced security but also significantly improved API performance, making them faster, more scalable, and better equipped to handle increased traffic and evolving business needs.

2. Certifications and Skills

During the migration, I am actively enhancing my understanding of Kong by utilizing Kong Learning resources and reviewing its extensive documentation. This ongoing learning strategy ensures that I remain informed about advanced features and best practices, facilitating a smooth and efficient migration process. My focus includes:

Kong Developer Certification
Kong Gateway Foundations
Kong Gateway Operations
Salesforce Certified MuleSoft Developer I.

Skills:

API Management: Hands-on experience with Kong Gateway and Apigee, using their features to effectively manage, secure, and optimize APIs for better scalability and performance.
Security: Knowledge of security policies like OAuth, API Key Verification, and JSON Threat Protection.
Programming: Dataweave in MuleSoft, JavaScript in Apigee, and Lua in Kong are all used for different purposes in API development and management:
1. Dataweave in MuleSoft: DataWeave is a strong data transformation language in MuleSoft. It's made to easily change data from one format to another. It is vital for connecting different systems by allowing effective data mapping and transformation as it moves through MuleSoft applications, ensuring systems work well together and communicate smoothly..
2. JavaScript in Apigee: JavaScript is used in Apigee for calling and routing target backend services. It allows developers to write custom scripts to manipulate request and response messages, implement custom logic, and enhance the functionality of APIs managed by Apigee.
3. Lua in Kong: Lua is a versatile scripting language used in Kong to develop and customize APIs. It empowers developers to create custom plugins and scripts to extend Kong's core functionality, enabling precise manipulation of API requests and responses. Lua is instrumental in implementing custom logic for critical API management tasks, such as authentication, rate limiting, logging, and other advanced operations tailored to meet specific business needs.
4. Cloud Integration: Our infrastructure team handles deploying and managing APIs in cloud environments using Kubernetes and the Kong Ingress Controller. This setup ensures high availability, smooth traffic management, and strong performance. I work closely with them to understand the deployment process and ensure seamless API integrations.
Monitoring: In our projects, we utilize Prometheus and OpenTelemetry plugins in Kong for monitoring API performance, complemented by Dynatrace for real-time insights and analytics. This robust setup ensures comprehensive visibility into API operations, enabling proactive issue identification and resolution. These tools collectively support tracking key metrics, tracing requests, and analyzing data, empowering informed decisions to optimize performance, reliability, and scalability of APIs.

3. Custom API Development

I design and build custom APIs in Kong, leveraging Lua scripting to manage API payloads and implement logging functionality, ensuring seamless API operations and tailored business solutions."

Case Study: Improving API Management for a Financial Institution

One of my most rewarding projects involved migrating APIs for a digital banking platform. Here’s how we solved the challenges:

Challenge: The old API system on Apigee had performance issues and high maintenance costs.
Solution: We moved the APIs to Kong Gateway, taking advantage of its lightweight design and flexible plugin features to enhance performance.
Outcome: API response times dropped by 30%, security improved with Kong’s OIDC plugin, and the client saved on maintenance costs.

This project demonstrated how Kong Gateway can significantly improve both performance and security.

What Sets Me Apart

Expertise: In-depth knowledge of Kong and Apigee for managing, securing, and optimizing APIs effectively. This ensures smooth integration, better performance, and strong security in different environments.
Problem Solver: Skilled at identifying issues and delivering solutions that align with business needs.
Continuous Learner: Always learning new skills and staying on top of the latest trends in API management!
