Hi there! I'm M. Ridwan Zalbina—feel free to call me Edo or Ridwan. I’m a Software Engineer with a strong foundation in full-stack development and a professional focus on Front-End Engineering. Currently, I serve as the Chief Technology Officer (CTO) at Payung Madinah, where I lead technology strategy, product development, and engineering execution.

I’m passionate about building scalable digital products and crafting intuitive user experiences. My interests span across software engineering, visual design, and information security. I also enjoy sharing insights and experiences through social media—covering topics such as UI/UX design, branding, and programming.

• Chief Technology Officer (CTO) — PT Payung Madinah Tour
• Former Front-End Developer — Fairtech Technology Pte. Ltd.
• Former Product Designer & Front-End Developer — NicheStack
• Technical Advisor — ISCTech, KAI Indonesia, HIPMI SUMSEL 2025-2028, DLH Lab Kabupaten Lahat etc.

Languages & Runtime
JavaScript/TypeScript · Python · PHP · Go · Kotlin — pemilihan stack berdasarkan constraint sistem, bukan preferensi.

Full-Cycle Delivery

• Front-end architecture, modern CSS, dan design system yang skalabel
• Backend service (REST/gRPC), job queue, dan integrasi pihak ketiga
• Aplikasi mobile
• Deployment & operasional di Linux: nginx, reverse proxy, process manager, CI/CD

Machine Learning (Production-Oriented)

• Pipeline end-to-end: ingest → feature engineering → training → evaluasi → inference
• Deteksi anomali sinyal RF dengan pendekatan unsupervised (Autoencoder, Isolation Forest)
• Monitoring drift dan retraining terjadwal

LLM Engineering

• Integrasi API, RAG di atas data internal, function/tool calling
• Alur agentic dengan guardrail dan fallback deterministik
• Eval set + regression test untuk output non-deterministik
• Tracing, kontrol biaya token, dan optimasi latensi

AI-Assisted Development

• Claude Code / Copilot-class tooling sebagai workflow harian
• Pola kerja: spec → generate → review ketat dengan test
• Output AI diperlakukan sebagai draft yang harus dibuktikan, bukan hasil akhir

Data Layer
MySQL · PostgreSQL · SQLite · MongoDB · vector store untuk retrieval — paham trade-off konsistensi, indexing, dan biaya query.

Technical Leadership
Memimpin keputusan arsitektur, memecah scope, dan menjaga codebase tetap bisa dirawat tim kecil.
