Florian Alexandru Serb Petrusel

I am a Software & Cloud Engineer focused on two main areas: optimizing infrastructure costs and building intelligent software solutions.

I help businesses and agencies scale their systems, automate deployments, and integrate AI without blowing their budget.

Here is what I bring to the table:

CLOUD & DEVOPS INFRASTRUCTURE

• Cluster Orchestration: Setting up Kubernetes (K8s) environments with a focus on self-healing, automated scaling, and zero-downtime migrations.

• Infrastructure as Code: Writing clean Terraform scripts to provision and manage multi-node architectures on Hetzner Cloud and AWS.

• Networking & Security: Configuring Cloudflare for DNS management, secure WAF rules, and edge caching to reduce server load.

AI & SERVERLESS ARCHITECTURES

• Serverless AI: Designing and benchmarking production-ready AI systems on AWS Lambda.

• RAG Optimization: Integrating Vector Databases (Pinecone) and LLM APIs (like Google Gemini) to process large datasets efficiently.

• Cost-Effective AI: Building hybrid systems that maintain high reasoning quality while keeping API usage costs as low as possible.

FULLSTACK DEVELOPMENT

• Backend: Building reliable services using Python, Java, and SQL databases (MariaDB, MySQL).

• Frontend: Developing fast, responsive user interfaces with TypeScript, JavaScript, React, and Next.js.

I like to combine solid software engineering principles with smart cloud management. If you need someone to fix a messy server setup, migrate your current stack, or integrate an AI feature efficiently, let's talk.
