Precious Ogbonna

I'm a Full-Stack Developer and Data Science Engineer with a unique blend of software engineering expertise and scientific training. With a background in Plant Science and Biotechnology from the University of Nigeria, Nsukka, I bring interdisciplinary thinking to every project I build—combining technical precision with analytical rigor.

Enterprise-Level Full-Stack Development

I architect and build production-ready web applications with complex architectures. My flagship project, DevConnect—a developer community platform—showcases my ability to handle enterprise-level challenges:

• Designed RESTful APIs with proper versioning, pagination, and advanced search capabilities
• Built dynamic React frontends with real-time WebSocket notifications
• Implemented multi-layered authentication (OAuth, JWT) with role-based access control
• Optimized performance using Redis caching to resolve N+1 queries and reduce database load
• Deployed containerized applications with Docker and CI/CD pipelines via GitHub Actions
• Integrated AWS S3 for scalable cloud storage solutions

Technical Stack: Django | PostgreSQL | React | Redis | Docker | AWS | Git

Data Science & Predictive Analytics

Beyond web development, I build intelligent, data-driven solutions. I developed a Diabetes Predictive Model that transforms complex medical data into actionable healthcare insights, demonstrating my ability to:

• Perform feature engineering and exploratory data analysis
• Build and validate machine learning models with statistical rigor
• Create compelling data visualizations that communicate insights to stakeholders
• Bridge the gap between raw data and business value

Database Architecture & Optimization

I excel at database management—from complex relational modeling to query optimization and performance tuning. I understand when to use SQL vs. NoSQL databases and implement data integrity, security, and scalability best practices across different paradigms.

My biotechnology background isn't just academic—it's a strategic advantage. I understand scientific workflows, speak the language of researchers, and grasp domain-specific challenges in AgriTech, FoodTech, and HealthTech sectors. This means I don't just code features; I build solutions that address real-world problems with contextual understanding.

I approach development with scientific methodology: hypothesis-driven problem-solving, rigorous testing, and data-informed decision-making. This combination of skills allows me to architect systems that are not only technically sound but also aligned with business objectives and user needs.

• Production-grade thinking: I build scalable systems that handle concurrent users, race conditions, and real-time interactions—not just tutorial-level code
• Cross-domain expertise: I can collaborate effectively with data scientists, domain experts, and business stakeholders
• Rapid learner: I've independently mastered complex technical stacks across web development, machine learning, and cloud services
• Quality-focused: I implement security best practices, write maintainable code, and deliver solutions that teams can build upon

I'm passionate about building technology that solves meaningful problems—whether that's improving food distribution systems, enhancing healthcare accessibility, or creating platforms that connect communities. I thrive in environments where I can apply both my technical skills and analytical mindset to deliver exceptional results.

Let's build something remarkable together.
