Mobile and Web Application Development

As a Full-Stack Developer and Machine Learning Engineer, I specialize in building end-to-end solutions that bridge robust mobile/web applications with intelligent backend systems. With 3+ years of hands-on experience in Flutter, React, Node.js, Django, and FastAPI, I deliver tailored software that addresses real-world challenges, particularly in fintech and enterprise productivity.

Core Technical Expertise

• Mobile Development:

  • Flutter: Pixel-perfect cross-platform apps using BLoC state management, custom animations, and deep linking (QR integration in Rate Eat).
  • Performance Optimization: Reducing APK sizes by 40%+ through asset optimization and code splitting.

• Web Development:

  • React/Redux: Dynamic UIs with server-side rendering (SSR) and responsive designs using Tailwind/Bootstrap.
  • Backend Engineering: Scalable REST/GraphQL APIs in Node.js (Express) and Python (Django, FastAPI), integrated with MongoDB/PostgreSQL.

• Machine Learning:

  • Predictive Modeling: Credit scoring and fraud detection pipelines using XGBoost, scikit-learn, and TensorFlow.
  • NLP: Sentiment analysis and document classification with spaCy/NLTK for automated workflows.

What I Deliver

1. Fintech Solutions:

   • Loan eligibility predictors trained on Ethiopian financial datasets.
   • Chatbots for banking FAQs using fine-tuned BERT models.
   • Risk assessment dashboards with Recharts/Matplotlib visualizations.

2. Enterprise Tools:

   • Document tracking systems with role-based access (Keycloak integration).
   • Real-time contest platforms with live leaderboards (A2SV’s Contest Central).

3. API-First Development:

   • Secure authentication flows (JWT/OAuth2).
   • Microservices architecture using Docker for deployment flexibility.

Differentiators

• Domain-Specific ML: Unlike generic AI developers, I focus on Ethiopian fintech datasets to build models that account for local economic patterns.

  • Clean Architecture Advocate: Maintainable codebases with SOLID principles, reducing tech debt by 30%+ in past projects.
  • Cross-Platform Efficiency: Single codebase strategies (Flutter + React) that cut development time by 50% while ensuring UI consistency.
  • Collaborative Leadership: Proven track record leading teams (Spark Tank, A2SV) with Git workflows and CI/CD pipelines.
