You will get an AI architecture audit of your product with a fix-first roadmap

Project details
You are building or running an AI product and something feels off — costs are creeping, the pipeline fails in ways nobody can explain, or you are about to scale and do not know if the architecture will hold. Before you hire a team or rebuild from scratch, spend three days finding out what is actually wrong.
I am a full-stack agentic engineer with 13+ years of hands-on engineering. In the last 13 months I delivered eight production AI platforms end-to-end as the single engineer — multi-agent systems, long-running LLM pipelines with metered billing, AI-assisted underwriting — across insurance, fintech, legal, travel and luxury retail. I have taken over systems that full teams could not move, so I know what failure looks like before it happens.
What you get: a written report in plain language, ranking what will break first, what it costs you today, what to fix now and what to leave alone. On Standard, add a 90-minute walkthrough call and a prioritized fix-first roadmap. On Advanced, I implement the top critical fixes myself and hand you a pull request you can merge.
No slideware. I read your actual code and I tell you straight.

Sketch Design to Static Site for Indie App
Vladimir is exceptionally talented and results driven. His modular approach to development and adept communication are above and beyond the job description and my expectations. Everything was completed on time; code was double checked for errors and each detail including even small adjustments for mobile phone margins was performed with acute accuracy.
My only hesitation writing a strong review is to save his availability for my future projects. I have personally developed my own sites with static site generators and I enjoyed working with him to try Hugo for the first time with a CMS.
In the future – I look forward to using the same technologies for similar results. I now have a static site with SVG graphics and an exceptionally fast load time. He is a JAM stack wizard. Thank you again, Vladimir!

Modify Hugo Static Site Template
Vladimir had the exact skills he said he did. He's a real pro, with the ability to complete tasks and to provide strategic direction. I got him started on some small tasks which he finished much more quickly than I expected, and overcame some initial challenges easily. This was my first project on Upwork (I'd used the old Elance platform), and will be hiring Vladimir again.
About Volodymyr
Full-Stack Agentic Engineer | Ship End-to-End | 13y Hands-On
Kosice, Slovakia - 8:18 am local time
Last 13 months: eight production platforms delivered end-to-end as the single engineer, across insurance, fintech, venture capital, legal, travel and luxury retail.
RECENT WORK
• Full tour-management ERP for a confidential tour operator, built solo — Fastify, React, PostgreSQL, ECS Fargate, Terraform. 1,000+ commits, empty repository to UAT in four months.
• Core SaaS engine over long-running AI pipelines for a startup whose funding round depended on shipping on schedule — it shipped on time, and the round closed.
• Schema-driven insurance underwriting portal with an AI-assisted review console. Next.js, Azure Functions, PostgreSQL, Microsoft Entra ID.
• AI-powered due diligence platform for professional investors.
• Event-driven multi-agent system on Firebase — eight specialised AI agents that plan, execute and audit work. In production.
BEFORE THE AGENTIC WORK
13 years as hands-on engineer, solution architect and team lead. At LitiGate I led platform engineering on an enterprise legal-AI platform used by Baker McKenzie, through two architecture migrations — one cut load time from 50 seconds to 1-2 seconds and retained an enterprise client that was about to leave. At Hacken I architected and launched 5+ Web3 security and blockchain analytics platforms.
STACK
Agentic & AI: multi-agent orchestration, tool calling, long-running LLM pipelines, prompt and context engineering, Anthropic and OpenAI APIs, Claude Code, Model Context Protocol (MCP), human-in-the-loop review, guardrails.
Application: TypeScript, Python, React, Next.js, Node.js, Fastify, NestJS, PostgreSQL, Prisma, Firebase, Angular, Vue.
Infrastructure: AWS (ECS Fargate, RDS, Lambda, Cognito, CloudFront), Azure Functions, Terraform, Docker, CI/CD.
I also maintain an open-source project, claude_mate — a hardware companion that monitors live Claude Code sessions. Python daemon, Arduino firmware, MIT licensed. My GitHub is linked on this profile.
I am based in Slovakia and work in CET, so European and UK clients get full working-hour overlap. I invoice B2B through my own company.
If you are deciding whether an agent architecture is the right answer at all, that is a conversation worth having before anyone writes code. Send me what you are building and I will tell you straight.
Steps for completing your project
After purchasing the project, send requirements so Volodymyr can start the project.
Delivery time starts when Volodymyr receives requirements from you.
Volodymyr works on your project following the steps below.
Revisions may occur after the delivery date.
Deep read of the codebase
I read the system end-to-end: architecture, AI pipeline, data layer, infra, security and cost hotspots. No meetings needed on day one.
Written report: ranked risks and quick wins
You get a written audit: what will break first, what it costs you today, what to fix now, and what not to touch. Ranked by impact, in plain language.
