ABOUT ME

Full stack JavaScript Developer with 10+ years of experience

I am a Senior Product Architect & Engineer with 10+ years of experience bridging product strategy, system architecture, and full-stack execution. I specialize in taking products from zero to one and architecting scalable, cross-platform applications across Web, Mobile (Capacitor/Ionic), and Desktop (Tauri/Electron).

I operate at the intersection of UX fidelity, clean system design, and business constraints—ensuring applications are fast, maintainable, and aligned with user needs.

Core Offerings & Focus Areas:

0-to-1 Product Architecture & Multi-Tenant Platforms: Designing modular, cloud-native frontend and backend systems (Next.js, Node.js, Python, PostgreSQL/Supabase, AWS) with strict isolation, high performance, and rapid deployment cycles.
AI-Native Applications & Interfaces: Architecting user-facing AI workflows with OpenAI and Google Gemini APIs. Specialization in building transparent interfaces requiring source attribution, confidence metrics, and audit trails.
Cross-Platform Product Strategy: Unified codebases powering Web, Hybrid Mobile (Ionic/Capacitor), and native-feel Desktop apps (Tauri/Electron) to maximize feature velocity and reduce maintenance overhead.
Design Systems & Frontend Infrastructure: Establishing robust component libraries (Tailwind, Radix/Shadcn) and end-to-end testing pipelines (Playwright) to accelerate teams without sacrificing UI polish.

Core Stack: TypeScript, React, Next.js, Node.js, Python, PostgreSQL, Supabase, Tauri, Ionic/Capacitor, React Native, AWS, Playwright.
