Talk: Concurrency Without the Complexity: Unleashing Virtual Threads (Project Loom) Part 2.

Abstract:
Aphiwe Vuba will be demonstrating Bank4Z a full stack, secure banking platform she's building with Spring Boot, PostgreSQL, and Flutter.
Bank4Z demonstrates how modern Java virtual threads replace complex reactive code with clean, high-throughput synchronous architectures handling concurrent account lookups, JWT-secured transactions, and database operations at scale without exhausting platform thread pools.

Talk: Programming without syntax: The compiler is an LLM

Abstract:
For decades, programming has meant translating ideas into syntax. But what happens when the compiler can understand intent directly?

This talk explores an experimental framework where developers write .prompt files instead of .java files, allowing software to be built from natural language descriptions rather than hand-written code.

Through live demos, I'll show how the system works, the engineering challenges involved in making it reliable, and what this shift could mean for the future of software development.

Speaker
Aphiwe Viba is a software engineering student at WeThinkCode_ who loves using tech to solve real-world problems. She also serve as a Recruitment Ambassador, which lets her dive into community outreach and help mentor the next generation of developers.

Lately, she's been channeling her focus into cybersecurity, learning how to bridge the gap between building cool digital innovations and making sure they are actually secure and resilient.
