Hire the Best WebRTC Developers
in Moldova

I’m a Senior Fullstack Engineer helping startups and teams build MVPs, SaaS platforms, mobile app backends, internal dashboards, AI tools, and Stripe-powered products. 🚀 I usually work with founders and product teams who need someone to turn an idea, Figma design, or messy existing system into a reliable product foundation. My core strength is backend architecture, but I also understand the full product flow: APIs, databases, dashboards, integrations, payments, cloud infrastructure, and the technical decisions needed to ship cleanly. What I can help with: 🚀 Building MVPs from scratch 📱 Backend systems for mobile apps 💻 SaaS platforms and subscription products 📊 Internal admin panels and business dashboards 💳 Stripe billing, subscriptions, webhooks, and payment flows 🤖 AI integrations using OpenAI and LLM workflows 🔌 API design, REST, GraphQL, and microservices 🗄️ Database design and backend logic ⚙️ Third-party integrations and automation workflows ☁️ Cloud/serverless deployment and infrastructure 🛠️ Refactoring, debugging, and scaling existing systems Tech stack: PERN/MERN, Node.js, Express.js, NestJS, React, Next.js, TypeScript, JavaScript, Python, PostgreSQL, MongoDB, Prisma, TypeORM, REST APIs, GraphQL, WebSockets, Redis, background jobs, queues, webhooks, Stripe, subscriptions, payments, OpenAI, AI APIs, LLM workflows, cloud platforms, serverless functions, Docker, GitHub Actions, CI/CD, and third-party integrations. Tools I’m familiar with: Slack, Notion, Jira, Trello. My focus is simple: understand the product, design the right technical structure, and build systems that are stable, maintainable, and ready to grow. If you’re building a new MVP, improving a SaaS product, launching a mobile app, or adding AI/payment features to your platform, I can help you plan and build it properly

Fullstack engineer with production experience across the full stack — React, Next.js, Node.js, Docker, Kubernetes, CI/CD. I own features end to end: backend logic, APIs, frontend integration, testing, and deployment. Currently building a real-time piano training SaaS — shipped WebRTC conferencing, Keycloak auth flows, and multi-cluster deployments. I deliver complete, tested, production-ready features.

I’ve been working as a developer since 2021. During that time, I’ve built and maintained a warehouse management system, a golf club registration and management platform, a booking system, and various service integrations. The most involved project was a Moodle-based e-learning platform where all customizations had been made directly in the core which made version updates impossible. I inherited that codebase, dug deep into Moodle internals, gradually migrated everything into proper plugins, and kept the platform running throughout. I came out knowing Moodle inside out. My most recent project is Tesuji—a real-time Go board game built with Laravel and Svelte. The hardest part was holding the entire game logic in my head at once and thinking it all the way through before writing a single line. I learn quickly and genuinely enjoy picking up new technologies — not chasing every trend, but diving deep when something is worth it. I think my strengths are patience, attention to detail, and the drive to fully understand what I’m working on - both the technical side and what the client actually needs. Core stack: PHP 8, Laravel, PostgreSQL, Redis, WebSockets, JavaScript, React, Vue.js, Docker.

Senior AI & Software Engineer 17 years building production systems end-to-end — from first commit to scale What I do best — I take complex systems from idea to production: AI agents that run end-to-end workflows, browser-native automations that survive at scale, full-stack SaaS that handles real load, and native apps that ship clean. I'm hands-on across the entire stack — frontend, backend, infra, data, mobile, and increasingly the deep stuff: forked browsers, on-device AI, post-quantum cryptography. I work fast, scope tight, ship clean. No hand-holding required. Where I'm strongest — AI Engineering: Claude Code, MCP Servers, Skills, Commands, AI Agents, Anthropic API, OpenAI API, Prompt Engineering, n8n, Workflow Automation, Multi-tool Pipelines Full-Stack Engineering: TypeScript, Node.js, Python, Go — React, Next.js, Tailwind CSS — REST APIs, GraphQL, WebSocket, Microservices — PostgreSQL, Citus, Redis, MongoDB, NoSQL, SQL — Custom Queues, Message Queues, RabbitMQ — Cypress, A/B Testing, SSR/ISR, Core Web Vitals, Performance Tuning Cloud & DevOps: Kubernetes, Cloudflare Workers / D1 / R2, Terraform, Helm Charts, Prometheus, Docker, GitLab CI, CI/CD, DigitalOcean, OVH, Linux Browser-Native & Automation: Chromium (native C++ SDKs), Browser Automation, Headless Browsers, Anti-Bot Detection, Web Scraping, Fingerprinting, Proxy Networks, Scrapy, Selenium, Puppeteer Mobile & Desktop: Swift, iOS, Kotlin, Android, React Native, Electron.js, Desktop Application Development, macOS Edge & On-Device AI: Edge Computing, llama.cpp, On-Device LLMs, Edge Inference Cryptography & Distributed Systems: Ed25519, X25519, Post-Quantum Cryptography, X3DH, PQXDH, Double Ratchet, Megolm, P2P Networking, Distributed Systems, Kademlia DHT, WebRTC, QUIC How I work — I architect first, then ship. I write specs when scope is unclear. I bring receipts: dashboards, metrics, working demos, not promises. I communicate async, deliver under tight deadlines, and don't disappear mid-project. Senior contracts only — Agents, MCP servers, SaaS platforms, native iOS, browser-native automation, distributed systems, edge AI. Remote-first. CET timezone. English, Romanian, Russian: fluent in all three. Available now. Send scope, timeline, and engagement type and I'll respond with a clear plan.
