  • • Designed and built the entire technical architecture of an end-to-end AI platform solo — market analysis, cost feasibility, MVP roadmap generation for startups.
  • • Built an LLM-based autonomous agent system integrating GPT-4, Claude, and Gemini, enabling non-technical users to prototype applications in natural language.
  • • Delivered full automation from idea to MVP alone — system design, API integration, and deployment, end to end.

Backend Developer — Tokush App

Dec 2024 – Nov 2025 · Remote

  • • Built secure data exchange systems for a barter-focused platform published on App Store and Play Store.
  • • Optimized matching algorithms, reducing query latency and system load in concurrent barter transactions.
