I build software that works — from low-level C++ systems to cloud-native SaaS platforms to full-stack web applications. With 20+ years spanning system programming, solution architecture, DevOps, and full-stack development, I bring senior-level judgment to every layer of a project. My edge is rare: I think at the architecture level and write production code. Having worn the hats of Product Owner and CTO earlier in my career, I bring business and product thinking to every technical decision — without losing sight of the code. What I do for clients: Whether you need an architect to design or audit a system, a full-stack developer to ship something end-to-end, or a senior pair of eyes on your codebase — I can own it. I also take on code and architecture review engagements: auditing codebases, identifying risks, and delivering actionable improvement plans. I work solo or integrate with your team. Selected projects: - D-ID — co-developed and continue to support the D-ID Studio mobile app (React Native) and built plugins for Microsoft PowerPoint and Canva, bringing D-ID's AI video generation into the tools people already use - AI integrations — integrated OpenAI, Gemini, and AWS Bedrock APIs into client products - 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." Core stack: C++ · Java (Spring Boot) · TypeScript · Node.js · React.js · Python · AWS (incl. Bedrock & serverless) · Google Cloud · Kubernetes · Docker · WebSockets · OpenAI API · Gemini API I hold Upwork's Expert-Vetted badge — awarded to the top 1% of talent on the platform. If your project needs someone who can think at the architecture level and still write production code, let's talk.

If your project does not exactly match my skillset, I will happily accept a lower rate if you still consider me. By being a quick learner and a reliable person with strict work ethics and strong knowledge base, I have delivered many projects where I had to learn along the way. Freelancing gives me a chance to be exposed to many different projects, current technologies and worldwide clients, with many different ideas and expectations. This helps me grow as a developer and as a professional. I enjoy working with different people, helping them to bring their ideas to life.
