Vladislavs Z.

I build and ship full-stack and cloud software (TypeScript, Node.js, React, AWS), and I can go deeper when a project needs it, from system architecture down to C++ and real-time media pipelines. With 20+ years across architecture, DevOps and hands-on development, including earlier time as CTO and Scrum Product Owner, I bring senior judgment to every layer and still write production code. What I do for clients: - Build full-stack products end to end: React front ends, Node.js/TypeScript backends, AWS (serverless and containers) - Integrate AI into products: OpenAI, Gemini, Anthropic and AWS Bedrock APIs - Audit architecture and codebases: risks identified, with a prioritized improvement plan - Handle performance-critical and real-time work: video/audio pipelines, streaming, and C++ where it's the right tool I use Claude and Claude Code daily in my own engineering work. Selected projects: - D-ID (since 2022) — a long-term engagement with the AI video generation company, starting with a Google Slides add-on. I co-developed and continue to support the D-ID Studio mobile app (React Native) and built plugins for Microsoft PowerPoint and Canva, bringing AI video generation into the tools people already use - VoxLift — my own voice-first AI gym-logging iOS app, built on AWS Bedrock and shipped to the App Store - License plate recognition system — inherited a C++ prototype built on custom ML models and took it to production: audited the codebase, produced a detailed remediation plan, and executed it. Client feedback: "one of the absolute best freelancers I've worked with in years" - Bitlevex — sole architect and full-stack developer for a cryptocurrency options trading platform; owned the entire technical stack from architecture to deployment on Google Cloud, Kubernetes, Java/Spring Boot, Node.js, React.js - Veset Nimbus — cloud playout SaaS for linear TV channels; led architecture and development, acted as Scrum Product Owner; hands-on C++ work using GStreamer What clients say: "Vlad was a C++ ninja that jumped right into our project, laid out a detailed, thoughtful, well-reasoned list of items that needed to be re-worked before release, and then executed in a methodical and deliberate way. His code is well-documented, well tested, and a thing of beauty. Vlad is truly a senior developer that would be a tremendous asset to any team." "Vlad brings honest, unbiased opinions about your codebase and sensible, well-reasoned solutions to improve it. His contributions are always based on industry best-practices. What's more, he brings his vast management experience to every decision — so there's a comprehensive understanding of the implications of each choice. A trusted guide and partner."

If your project needs someone who can think at the architecture level and still write production code, let's talk.
