Vuldak

API Development Webinars

Since 2025

Real API knowledge from developers who actually build them

No theory without practice. No slides without code.

We started Vuldak because most API courses teach outdated patterns while real-world development keeps moving forward. Our instructors write production APIs during the day and teach what actually works in the evening.

How we teach API development differently

Live coding, not presentations

Every webinar involves writing actual code. You watch the instructor build endpoints, handle errors, test responses. When something breaks, you see how to debug it. When performance lags, you learn optimization techniques that work.

Our sessions run longer than typical webinars because we refuse to skip the messy parts. Authentication doesn't always work on the first try. Rate limiting needs proper testing. Error handling requires thinking through edge cases.

Production-grade patterns

RESTful design, GraphQL optimization, WebSocket implementation with actual scalability considerations and security hardening.

Direct Q&A during sessions

Ask about your specific use case while the instructor's editor is open. Get feedback on your architecture decisions in real time.

Mobile app integration examples

See how APIs connect to mobile recharge systems and mobile app backends with proper error handling and retry logic.

Command-line debugging workflows

Watch instructors use cURL, Postman, and logging strategies to track down issues in API responses and request handling.

Why developers from 67 countries join our sessions

Time zones make live attendance challenging, but recordings stay available. The interactive chat remains open for questions even after the session ends. Instructors review comments and update materials based on what people struggled with.

Multilingual support means technical terms stay in English while explanations adapt to your language. Code speaks universally, but context helps when you're working through authentication flows or webhook implementations.

Instructors who write APIs for production systems

Risto Mäkelä teaching REST architecture patterns

Risto Mäkelä

Lead Instructor - REST Architecture

Backend specialist focused on teaching scalable API patterns and security implementations. Builds financial APIs handling 2M+ daily transactions.

Pavle Dimitrov demonstrating GraphQL optimization techniques

Pavle Dimitrov

Technical Education Director

Develops curriculum for GraphQL optimization and real-time API communication protocols. Previously built messaging APIs for 40M+ users.

What happens in a typical session

We start with a specific problem: "Build an endpoint that handles file uploads with progress tracking." The instructor codes it from scratch, explaining design decisions as they type. You see the entire process including the parts that need refactoring.

Testing happens live. Requests fail, responses return unexpected data, edge cases appear. The debugging process shows you how to think through API issues systematically rather than guessing solutions.

Available for enrollment right now

Current sessions cover REST fundamentals, GraphQL schema design, authentication strategies, rate limiting implementation, and WebSocket protocols. Each runs 90-120 minutes with hands-on coding exercises.

Sessions repeat monthly with updated examples based on new framework releases and evolving best practices. Material stays relevant because instructors update code examples when libraries change or security recommendations shift.
