Building the Frontend of Modern Web
I create interfaces that look sharp, run fast, and scale without friction — from first sketch to final build.
Scalable design for modern apps
High-performance React frontends built with clean architecture, smooth motion, and detail-oriented design.
API Integration
Connect and integrate third-party services to enhance functionality and data exchange in your web app.
Meta Tags Optimization
Optimizing title tags, meta descriptions, and header tags with relevant keywords helps search engines understand your content and improves click-through rates.
Responsive Design
Ensuring the site is mobile-friendly and adapts to all screen sizes, which is a critical factor for SEO and user satisfaction.
Services
Creating fast, modern, and fully responsive web applications.
Converting
Transforming design files into clean, pixel-perfect web layouts.
Use Meaningful Variable Names
Choose descriptive variable names that clearly indicate their purpose. This improves readability, makes the code easier to understand for others (and your future self), and reduces the chance of logic errors.
Keep Functions Small and Focused
A function should do one thing and do it well. Keeping functions small not only improves readability, but also simplifies testing, debugging, and future refactoring.
Avoid Global Variables
Use local variables or encapsulate state within functions, modules, or classes. This prevents unintended side effects, reduces coupling, and improves code modularity.
Use Consistent Formatting
Follow a consistent code style—including indentation, spacing, and naming conventions—to make your codebase easier to navigate and collaborate on across teams.
Write Modular Code
Break your code into small, reusable modules or components. Modular code improves maintainability, supports testing, and scales better as your project grows.
Use Comments Wisely
Write comments when necessary to explain complex or non-obvious logic. Avoid restating what the code clearly expresses, and aim for clarity and precision in your explanations.
Handle Errors Properly
Use try-catch blocks, validate inputs, and provide meaningful error messages. Proper error handling ensures your application behaves predictably and aids in debugging.
Optimize Loops and Conditions
Avoid unnecessary iterations, redundant checks, or inefficient structures. Aim for clarity without sacrificing performance, especially in large datasets or nested logic.
Avoid Hardcoding Values
Store configurable values in constants, environment variables, or configuration files. This enhances flexibility and eases updates across environments.
Use Version Control
Leverage Git or another version control system to track changes, collaborate with others, and maintain a clear history of your codebase over time.
