Transformers & Attention: Teaching Models Where to Focus
Transformers revolutionized deep learning by replacing sequential processing with the Attention Mechanism, allowing models to weigh the importance of different input elements simultaneously. Introduced in the landmark paper Attention Is All You Need, this architecture enables parallel computation, captures long-range dependencies efficiently, and powers modern breakthroughs in NLP and beyond. Today, transformer-based models form the backbone of systems like BERT and GPT, driving applications from translation to generative AI.
Modular Monolith
A modular monolith is a software architecture that combines the simple deployment of a traditional monolith with the organized, loosely coupled structure of microservices. It acts as a single, unified codebase and deployment unit, while internally separating code into domain-specific, independent modules with clear interfaces (e.g., in systems like Shopify or GitHub).
Event-Driven Architecture
Useful for workflows involving background jobs, notifications, integrations, async processing, and reliable cross-system communication.
