Skills and Tools

I specialize in building responsive, performant web applications with clean, modern UI/UX design.

My frontend work includes developing:

• Interactive web applications with React.js and Next.js
• Real-time data visualizations and dashboards
• Responsive designs with Tailwind CSS and Bootstrap
• Component libraries and design systems
• Landing pages and marketing websites

Here are the frontend technologies I'm proficient with:

JavaScript & TypeScript

JavaScript and TypeScript are my primary programming languages for web development.

I use TypeScript for building type-safe applications, especially in large-scale projects where code quality and maintainability are critical.

React.js

React is my go-to library for building modern, interactive user interfaces.

I've built multiple production applications with React, including real-time dashboards, analytics platforms, and content management systems.

Next.js

Next.js is my preferred framework for building full-stack React applications with server-side rendering and API routes.

Used it to develop projects like HarmonyAI (Personal Health Assistant) and Learning Management System.

Tailwind CSS & Bootstrap

For styling, I primarily use Tailwind CSS for its utility-first approach and Bootstrap for rapid prototyping.

Both frameworks help me build responsive, mobile-first designs efficiently.

HTML & CSS

Strong foundation in semantic HTML and modern CSS, including Flexbox, Grid, and CSS animations for creating pixel-perfect designs.

I specialize in building scalable backend services, RESTful APIs, and microservices architectures with a focus on performance, security, and maintainability.

At ExoSystem, I developed backend services handling 10,000+ active users with 99% uptime. My backend expertise includes:

• RESTful APIs and GraphQL for efficient data management
• JWT authentication and secure authorization systems
• Microservices architecture with Node.js and Express.js
• Database optimization (MySQL, PostgreSQL, MongoDB, Redis)
• Real-time features and WebSocket implementations
• AWS deployment (EC2, SES, S3) with 99% uptime
• API response optimization (achieved 25% reduction in response times)

I've also published sachii-safe-logger on npm, a secure logging utility for Node.js applications.

Node.js & Express.js

Node.js with Express.js is my primary backend stack. I've built production-ready APIs handling thousands of users.

Used in projects like Campaign Management System (newsletter platform with AWS SES integration) and HarmonyAI (AI health assistant with real-time chat).

GraphQL

Implemented GraphQL APIs for efficient data management at ExoSystem, reducing API response times by 25%.

GraphQL's query flexibility and type safety make it ideal for complex data requirements.

Python, Django, Flask

Proficient in Python with frameworks like Django and Flask for rapid backend development.

Used for building automation scripts, API services, and web applications.

Go & C++

Experience with Go for high-performance services and C++ for system-level programming and algorithmic problem-solving.

I have hands-on experience with cloud infrastructure, containerization, and CI/CD pipelines for deploying and maintaining production systems.

At ExoSystem, I utilized AWS services (EC2, SES, S3) for deployment, achieving 99% uptime for production systems.
