Practices
How I work
Patterns from 13 years of contract and freelance engineering.
Ramps up fast
80+ projects across different stacks and domains. The resume shows joining codebases in TypeScript, PHP, Ruby, Python, Kotlin, and more — each time at a different company.
Full-stack ownership
Backend, frontend, infrastructure, and deployment work across almost every role. Not just one layer.
Remote and async
Almost every role listed as remote. Only 2 of 14 company roles were in-office. 13 years of remote contract work.
AI-native engineering
I ship features through PRD-driven agentic loops — structured requirements, autonomous implementation, deterministic verification. Daily tools: Claude Code for coding, Ralph for orchestration. FinancialDocs and NIXAP were both delivered this way.
"Andrei is a one of a kind senior AI-powered developer that would be an immense added value on any team. Not only is he a master of the latest Agentic-AI workflows, but he ensures the quality of work that comes out is impeccable. He uses very sophisticated AI workflows for producing any full-stack feature in very fast speed with top-notch quality. For anyone looking to hire Andrei on any project, you cannot go wrong, hire immediately; he will make your project much better, and very fast. The best developer I've come across in the past 20 years or so. This is what a top-notch developer should look like in 2026."

Working across many stacks
TypeScript, JavaScript, PHP, Ruby, Python, Kotlin, Go, C#, Elixir, Delphi. TypeScript and PHP are where I've spent the most time. Depth varies — some stacks I've used on a single project, others across many years and teams.
80+ projects as a freelancer
Delivered 80+ projects across CRM, SaaS, and e-commerce — handling client requirements, architecture, implementation, and ongoing maintenance end-to-end.
Legacy codebases
At FinancialDocs, maintained three legacy paystub platforms while building a new legal document platform — evolving a shared codebase of 2,000+ service classes without breaking production across three interconnected products.
Agentic AI development
I work through PRD-driven agentic loops: structured requirements go in, an autonomous AI agent implements each story, verification runs after every iteration. Built my own orchestration CLI (Ralph) to formalize this — it works with any AI coding tool. FinancialDocs and NIXAP were both shipped this way.
Let's build something together
If you're looking for a full-stack engineer who can own a project end-to-end — architecture through deployment — I'd like to hear about it.
