(no idea) ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • 100% Job Success across every contract — no walk-aways, no drama • Long-term clients (multi-year engagements, not one-shot gigs) • I write a plan before I write code, and I tell you when something is a bad idea — even when you're paying me to do it • Async, reliable communication. I deliver in writing, not in vibes. What I won't do: spam, ad fraud, DDoS, scraping with intent to violate ToS where it actually matters, or anything that puts your business at legal risk. Web scraping is legal when done right — I do it right. If you've got a backend that's buckling, a scraper that broke last week, or a data-extraction project nobody else wants to take on — send the details and I'll tell you straight whether I'm the right fit. — Arthur

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.
