FAQ

Frequently asked questions

The things recruiters and clients usually ask on the first call.

What technologies do you specialize in?

I specialize in modern web technologies including React, Next.js, TypeScript, Node.js, and Go. For cloud and DevOps, I work extensively with AWS (Lambda, SAM, Bedrock), Azure (Functions, Logic Apps, OpenAI), Docker, and Kubernetes. I'm also experienced in AI integration, prompt engineering, and RAG systems.

What cloud platforms do you work with?

I have extensive experience with AWS (certified Solutions Architect and Cloud Practitioner), Microsoft Azure, and Google Cloud Platform. My expertise includes serverless architectures, containerization, Infrastructure as Code, and cost optimization across all three major cloud providers.

Do you have experience with AI and LLM integration?

Absolutely. I have hands-on experience with prompt engineering, building RAG (Retrieval-Augmented Generation) systems, implementing MCP (Model Context Protocol), and integrating LLMs from OpenAI, Anthropic, and Azure OpenAI Service. I also specialize in AI cost optimization and observability.

What is your approach to DevOps and automation?

I believe in infrastructure as code, automated CI/CD pipelines, and comprehensive observability. I use tools like AWS SAM, CloudFormation, Docker, Kubernetes, and GitHub Actions to create reproducible, scalable infrastructure. I also implement monitoring with Application Insights, CloudWatch, and custom KQL queries.

Can you help with code audits and security reviews?

Yes, I perform comprehensive code audits using SonarQube for code quality and OWASP ZAP for security vulnerability assessment. I can identify critical vulnerabilities, outdated dependencies, and provide modernization recommendations for legacy systems.
