Golang

Introduction # In the landscape of 2025, security isn’t just a feature; it’s the foundation of any viable software product. While Go (Golang) is celebrated for its memory safety and concurrency models, it is not immune to vulnerabilities. Mismanaged pointers, race conditions, and improper input handling can still leave your application wide open to exploitation.

Image processing is a staple requirement for modern backend systems. Whether you are building a user profile system that needs to generate thumbnails, an e-commerce platform that needs to standardize product photos, or a content management system (CMS) handling massive uploads, the way you handle images matters.

In the landscape of modern backend development in 2025, users have zero tolerance for slow or dumb search bars. Whether you are building an e-commerce platform, a log aggregator, or a content management system, the expectation is Google-like speed and relevancy.

Mastering Go Generics: Practical Patterns for Clean Code # If you were coding in Go before version 1.18, you likely remember the struggle. You needed a Min function for integers, then another for floats, and maybe a third for a custom numeric type. Or worse, you resorted to interface{} and runtime reflection, sacrificing compile-time safety for flexibility.

Implementing Robust Rate Limiting and API Throttling in Go # In the modern landscape of backend development, APIs are the lifeblood of software ecosystems. However, an unprotected API is a ticking time bomb. Whether it’s a malicious DDoS attack, a buggy client script sending infinite retries, or simply an unexpected viral surge, traffic spikes can bring your services to their knees.

Introduction # In the landscape of modern web development, handling payments is the “final boss” for many backend engineers. It requires a confluence of security, reliability, and precision. If a blog post fails to load, it’s an annoyance; if a payment fails (or worse, is double-charged), it’s a business crisis.

Introduction # In the landscape of 2025, where microservices run on constrained Kubernetes nodes and cloud bills are scrutinized to the cent, efficient memory management is no longer optional—it is a core competency for any senior backend engineer.

Introduction # It is the dawn of 2026, and despite the rise of push notifications, Slack bots, and in-app messaging, email remains the undisputed backbone of transactional communication. Whether it’s a password reset, a purchase receipt, or a weekly digest, your Go application needs to send emails—and it needs to do so reliably.

Introduction # In the era of 2025, where HTTP/3, gRPC, and GraphQL dominate the headlines, it is easy to forget the foundational layer that powers the internet: TCP (Transmission Control Protocol). While high-level abstractions are excellent for general web development, there is a specific tier of engineering—real-time trading systems, IoT device communication, multiplayer game servers, and internal RPC backbones—where overhead matters.

Introduction # If you are stepping into a Go interview in 2025, you can bet your bottom dollar on one thing: You will be grilled on concurrency.
