Hey, I'm Harsh Kumar Khatri 👋

Twitter Badge Linkedin Badge Medium Badge YouTube Badge Gmail Badge

Mobile & Backend Developer based in Hyderabad with 4+ years of experience building production applications. I've taught Flutter & Dart to 54,000+ students on Udemy and run the Hexhybrids YouTube channel covering Flutter, Firebase, and developer career growth.

I build things end-to-end — from database schemas and REST APIs to polished mobile interfaces. Currently exploring how AI and data-driven features can make apps smarter.

🔧 What I Work With

Mobile & Frontend: Flutter, Dart, Riverpod, Firebase, Platform Channels (Android/iOS)

Backend & APIs: ASP.NET Core, Node.js, Express, REST API Design

Databases: PostgreSQL, MongoDB, Firebase Realtime DB & Firestore

Cloud & ML Services: AWS (Rekognition, S3), Sentry, CI/CD Pipelines

Languages: Dart, C#, JavaScript, Python, Java

Data & ML: pandas, NumPy, scikit-learn, NLP basics, Sentiment Analysis

🚀 What I'm Building

  • HealthTrack — A full-stack wellness app (ASP.NET Core 8 + PostgreSQL + Flutter/Riverpod) with a structured Indian nutrition database, macro/micronutrient tracking, and AI-agent-ready task architecture.
  • Hexhybrids — YouTube channel & content series covering Flutter deep dives, Firebase integrations, and a developer career series called Career Chronicles.

💼 Experience Highlights

  • Shipped production Flutter apps handling real-time data, complex state management, and platform-specific integrations.
  • Built fintech backend services with Node.js, MongoDB, and secure transaction workflows.
  • Debugged production-grade issues — ANR traces, platform channel conflicts, third-party SDK interference (Sentry).
  • Designed database schemas, API contracts, and PRDs for full-stack applications from scratch.
  • Freelanced and built startup products as the sole/primary mobile developer.

📝 I Also Write

Long-form technical articles on Medium covering Flutter architecture, developer productivity, and engineering career insights.
