Hire the Best Semantic UI Specialists
in Serbia

I am a UI developer with i++ years of experience - the glue between front-end, backend, and design. Not from an arts academy, yet instinct tells me when a color palette is off or a space is missing between words. My core competency lies in the fine details: semantic, accessible, and SEO-friendly HTML built with WCAG, WAI-ARIA, and Schema.org in mind. I think before I code - and while I use AI copilots to boost productivity, I keep them on a short leash. If you care about accessibility and the subtle details; if your project is clever, useful, and a step toward Wor(l)d Peace ;-) you’re in the right place. My Flappy Bird score is 687 🐦.

I build production AI systems that hold up under real usage — not demos, not prototypes. Systems that ship, scale, and stay reliable when real users start hitting the edge cases. What I do: - Production LLM systems — RAG pipelines, multi-agent orchestration, and the eval frameworks that actually measure whether a change improved anything. - AI architecture & builds — designing and shipping the system properly the first time, then handing it off clean to your team. - Cost & reliability engineering — controlling inference spend, hardening prompts, and adding the observability production AI actually needs. - Team enablement — installing the Claude Code and agentic-development workflows that make your engineers dramatically faster. Recent work: - TraceLayer — compliance-automation SaaS (11 frameworks, 120+ integrations) built solo to paying customers in 21 days using multi-agent LLM orchestration. - Kandji — enterprise-scale RAG and LLM automation with MLOps for a leading device-management platform. - Acumatica — multi-agent LLM pipeline with stateful context memory, running in production. - Fresh Earth — real-time carbon-tracking and ESG compliance platform (Chief of AI). - Volvo Group — predictive-maintenance ML and IoT pipelines (15% less fleet downtime). Stack: Python, FastAPI, Next.js, React, TypeScript, LangChain, OpenAI and Claude, RAG, vector databases, AWS, Docker, PostgreSQL. How I work: embedded with your team, not an external vendor delivering tickets. Weekly demos, async by default, full context on what you are building and why. If you have a real AI engineering problem — an LLM feature that has to work in production, a system that needs to be built right the first time, or a team that needs to move faster — let's talk.

Is your business invisible when customers ask ChatGPT, Perplexity, or Claude for recommendations? You're not alone — most websites are completely absent from AI search results, and they're losing customers to competitors who aren't. I help businesses get found and cited by AI engines (ChatGPT, Perplexity, Claude, Google Gemini) through Generative Engine Optimization (GEO) and Answer Engine Optimization (AEO). Here's what makes me different from most "AI SEO" freelancers: I'm a senior full-stack developer with a 100% Job Success Score. I don't just write generic advice — I actually implement the technical work that gets you cited: schema markup, structured data, the llms standard files, hreflang, and AI-readable content architecture. You get strategy AND execution from one person. WHAT I DO: - AI Visibility Audit — I test how your site appears across ChatGPT, Perplexity, Claude, and Gemini for the exact queries your customers ask, and show you which competitors are winning and why. - Technical AI Optimization — Schema structured data, the llms standard files, hreflang, FAQ schema, and content restructuring for AI extraction. The technical foundation AI engines actually read. - Cross-Language AI Visibility — A specialty: making local-language websites discoverable to foreign-language AI users. If your customers search in English, German, or French but your site is in another language, you're invisible. I fix that. - Ongoing Monitoring — Track your citation rate over time across all major AI engines, see what's working, and stay ahead of competitors. WHO I WORK WITH: Local businesses, tourism and hospitality (restaurants, hotels, clinics, tour operators), SaaS companies, and agencies who want their brand to appear in AI-generated answers — not just page-two search results. MY TECHNICAL BACKGROUND (THE PROOF): - Frontend: React, Next.js, JavaScript (ES6+), TypeScript - Backend: Node.js, Express.js, Python - CMS and Data: Strapi, WordPress, PostgreSQL, MongoDB - SEO and GEO: schema markup, structured data, technical SEO, Core Web Vitals, hreflang - Languages: Native English and Russian I value clear communication, honest expectations, and measurable results. I won't promise you guaranteed number-one rankings in ChatGPT — no honest provider can, because the AI engines control that. What I promise is correct technical implementation, transparent measurement, and continuous optimization based on real data. Want to see how visible your business is to AI right now?
