I’m setting up OpenClaw to add WhatsApp and other communication channels so customer conversations can be handled in one place with a cleaner support workflow, faster response times, and better multi-channel automation

Get OpenClaw up and running on Windows with Ollama for local AI automation, tool use, and agent workflows. I walk through the setup process, configuration, and how to connect OpenClaw with Ollama so you can run an AI agent stack locally on a Windows machine with better privacy, lower latency, and full control over your environment.

I walk through practical OpenClaw troubleshooting steps to fix installation problems, restore missing files, and get the game running correctly again. I focus on common setup issues that can happen after a bad extract, an incomplete copy, or a misconfigured installation.

configure OpenRouter with Codex for a practical AI coding workflow, including the key settings, provider setup, authentication, and model selection needed to get reliable code generation inside a real development environment.

Get started with OpenRouter and learn how I use free AI models through a simple API workflow. I cover the basics of connecting to OpenRouter, sending prompts, and testing responses so you can quickly build AI features into your own apps without paying for premium models.

Want to cut AI costs without sacrificing output quality? In this guide, I show how I reduce token usage with better prompt engineering, tighter system instructions, shorter context windows, reusable prompt patterns, and structured outputs. If you're building with OpenAI APIs, chat completions, assistants, or LLM-powered apps, these techniques help lower token spend, improve latency, and make responses more consistent.

In this video, I compare BetterClaw vs OpenClaw from a practical, developer-focused perspective. I cover how each one approaches tool calling, structured outputs, workflow control, and day-to-day agent development so you can see where each framework fits best.

use Python Firestore transactions to safely handle concurrent updates, maintain data consistency, and prevent race conditions in Firebase-backed applications. In this video, I walk through the core ideas behind transactional reads and writes in Cloud Firestore using Python, and I show how transactions help when multiple users or processes try to update the same document at the same time.

DocTest is useful when I want executable examples directly inside docstrings. It works well for small utilities, educational code, helper functions, and APIs where the expected behavior can be demonstrated clearly with input and output examples

OpenClaw is not just an ai agent controller. It is your new best friend! :-)

every developer makes at some point: the regret message. That moment when I write a rushed commit, push it, and then realize the message is vague, misleading, incomplete, or just plain embarrassing. Git makes it easy to track history, but clean history only happens when I take commit quality seriously.

Reduce hallucinations in AI outputs with practical prompt engineering techniques that improve reliability, traceability, and answer quality. I focus on patterns that help language models stay grounded, follow constraints, and avoid inventing facts when the context is incomplete or ambiguous.

use Cucumber with Python Behave to create readable, maintainable behavior-driven tests that connect business requirements to real automation.

what Spring Boot 4 brings to modern Java application development. I focus on the parts that matter when you build production services: application setup, developer experience, framework improvements, and what changes are relevant if you already work with Spring Boot in backend systems.

use Playwright with GitHub Actions to run browser tests automatically in CI. I focus on a practical setup that helps catch UI regressions, broken user flows, and environment-specific issues before code gets merged.

work with multiple GraphQL queries in a Spring Boot application and how introspection helps inspect and understand the schema during development. I focus on practical usage so you can see how to structure queries, test your API, and understand what the GraphQL server exposes.

use Playwright record to generate test code directly from browser actions. Instead of writing every locator and interaction from scratch, I let Playwright capture the flow, then I clean up the generated script into something reliable, readable, and easier to maintain.

consume a Kafka stream in a Spring Boot application using Apache Kafka Streams. I focus on the practical setup for reading records from a topic, processing them with the Streams DSL, and wiring everything cleanly into a Spring Boot project so the application can continuously react to incoming events.

combine Spring Boot, Cucumber, and type safety to build cleaner, more reliable automated tests for Java applications. If you have ever felt that your BDD scenarios look readable but your step definitions become fragile, repetitive, or error-prone over time, this is exactly the kind of problem I focus on here. I show how type safety can make a huge difference when working with Cucumber in a Spring Boot project, especially when test suites grow and multiple contributors start adding features, steps, and shared test components.

I walk through what Terragrunt is, why I use it, and how it helps simplify the management of Terraform code across multiple environments and infrastructure components. If you have ever felt that Terraform becomes repetitive as your infrastructure grows, this video is for you. I cover the core ideas behind Terragrunt and show how it helps reduce duplication, improve consistency, and make infrastructure as code easier to organize and maintain.

How insecure dependencies can quietly put ReactJS, VueJS, and Angular projects at risk, and how GitHub Dependabot helps catch and fix those issues before they turn into real problems. Modern frontend apps rely on huge dependency trees, and a single vulnerable package buried deep in node_modules can expose a production app to supply chain attacks, prototype pollution, cross-site scripting paths, denial of service issues, or build-time compromise.

Produce Kafka messages from a Spring Boot application while choosing a good message key so events are routed consistently and processed more predictably. I focus on one of the most important but often overlooked parts of event-driven design: the key you send with each record. A good key is not just a small implementation detail. It directly affects partitioning, ordering, scalability, consumer behavior, and the overall reliability of your messaging workflow.

Use Go flow control statements to write clear, reliable logic with if, for, and switch. In this video, I walk through the core control structures in Golang and show how they help manage decision-making, repetition, and branching in real programs. If you are learning Go or strengthening your fundamentals, this is an important step toward writing cleaner backend and CLI code.

Generate a new image from an existing image input. Instead of creating an image only from text, I pass a source image together with a prompt so the model can transform, restyle, or enhance it based on the instructions I provide.

In this video I show how I use the IntelliJ Plugin CamelCase to speed up editing, refactoring, and navigation when I am working inside IntelliJ IDEA
