Job Description

Business Overview:

We are a B2B SaaS company. Our web application has seen a sharp increase in user traffic, and our users are complaining about slow load times and poor performance.

The Challenge:

Our web application is not optimized for performance. The page load times are slow, and the application becomes unresponsive during peak traffic hours. We need to refactor and optimize the code to handle a large volume of concurrent users.

Problems Caused:

The poor performance is directly impacting our user experience and customer satisfaction. It leads to user churn and negatively affects our brand reputation. The lack of scalability is a major bottleneck for our business growth.

Proposed Method:

We need a senior web developer to identify and fix performance bottlenecks. This involves a comprehensive audit of our front-end and back-end code. The freelancer will:

Code Audit: Analyze the codebase for performance issues.
Database Optimization: Optimize database queries and schema.
Front-End Optimization: Implement techniques like code splitting, lazy loading, and image optimization.
Scaling: Implement a scaling strategy for our back-end services.

Required Experience:

At least 4+ years of experience in full-stack or backend development. The freelancer must have a proven track record of successfully optimizing high-traffic web applications.

Required Expertise:

Deep expertise in web performance optimization.
Strong knowledge of database query optimization.
Experience with front-end performance tools (Webpack, Lighthouse).
Proficiency in a backend framework (e.g., Node.js, Ruby on Rails, Django).

Sample Work Required:

Please provide a case study or a report from a past performance optimization project, detailing the issues identified, the solutions implemented, and the performance improvements achieved.

Freelancer Proposal:

The freelancer should submit a detailed technical proposal outlining their approach to the performance audit, the specific areas they will focus on, and a phased plan for implementation.
