I build and evolve complex Svelte applications. Architecture, code, testing, deployment. 8 years with Svelte/TypeScript · 15 years in commercial development. WHAT I DELIVER - Svelte 5 / SvelteKit frontend - from scratch or continuing existing projects - Node.js backend - REST APIs, WebSockets, database integration - AI integration - OpenAI/Anthropic APIs, prompt engineering, contextual AI features - Multi-app architecture - 10+ app variants from a single codebase, no code duplication - Progressive Web Applications (PWA) with offline-first capabilities - High code quality and architecture that ensures long-term maintainability - AI-accelerated development - quality-first approach RESULTS - EdTech PWA (current project). AI-driven language learning with text-to-speech, pronunciation training, and spaced repetition - Svelte 5, SvelteKit, OpenAI/Anthropic APIs. - 10+ app variants from one codebase. Composable architecture for Svelte: add a new app by swapping features, not copy-pasting code. Stress-tested, proven in production. - 5 rental websites delivered from scratch. ~3 months per site, real customer orders across multiple markets. - School emergency response app. Interactive map with real-time feedback for US schools. TECH STACK - Frontend: Svelte/SvelteKit (latest) · TypeScript · Vite · Tailwind · Plain CSS/PostCSS - Backend: Node.js · REST API · WebSockets · MongoDB - Architecture: Composable feature system (Reactive DI) · PWA · Service Workers - AI: OpenAI API · Anthropic API · Claude Code · GitHub Copilot - Testing: Vitest · Playwright · Randomized stress testing HOW I WORK - Remote, async - written English communication - Daily progress updates - Up to 30 hours per week - Comfortable joining existing projects and collaborating with other developers - UTC+7 - overlap with EU afternoon / US West Coast evening TWO ENGAGEMENT MODELS 1. Rapid Prototyping (AI-first) - maximum speed for specs, prototypes, MVPs. 2. Production-Grade Development (Quality-first) - solid architecture, structured for long-term evolution.
