Rohani S.

I build production web applications — from database schema to deployed API to the UI in front of it. WHAT I BUILD Full-stack web applications PHP/Laravel and Node.js backends paired with React, Vue, and Next.js frontends. I have shipped CRMs, ERPs, payment integrations (virtual accounts, digital signatures), and content platforms end to end — not just the code, but schema design, deployment, and server management too. APIs and integrations REST APIs, OAuth2, payment gateways, cloud storage (AWS, GCP), and third-party service integration. Built for real production traffic, not just demos. AI integration I add AI into existing applications rather than starting from a blank slate — chatbots, AI agents, and LLM-powered features wired into your current stack. I also run self-hosted, open-source LLM inference (vLLM, Ollama) for teams that cannot send data to third-party APIs, and I work in Rust (Actix, Axum) when a service needs to be rewritten for performance or cost. STACK Web: PHP, Laravel, JavaScript, TypeScript, React, Vue, Next.js, Nuxt.js Backend/Data: Node.js, PostgreSQL, MySQL, Redis AI: LLM integration, AI agents, vLLM, Ollama, RAG Infra: Docker, Nginx, Ubuntu server management, AWS, GCP Also: Rust (Actix, Axum) for performance-critical rewrites Mobile: Kotlin, Java, Android Studio, Audio Player BACKGROUND Production software engineering across full-stack web, mobile (Android), and backend systems. Built full management platforms end to end — CRM, ERP, audio streaming/CMS platforms — without relying on vendor templates. Tell me what you're building and where it's stuck, and I'll tell you the fastest way to get it working.
