Senior Performance & UI Engineer — Optimization and Professional Upgrade (Laravel + AWS)
Budget: $250 – $500 USD
Context
The mandatory technical milestones have already been completed.
The system is functional.
What is still required:
• Real performance optimization
• Structural scalability preparation
• Professional SaaS-level UI refinement
• Final consolidation before public launch
This project does NOT involve rewriting financial logic or rebuilding the system.
Scope
Performance & Scalability Optimization
• Advanced NGINX and PHP-FPM tuning
• Redis implementation for sessions and cache
• Database query and index review
• MySQL parameter optimization
• Bottleneck identification and elimination
• Proper HTTP caching implementation
• CDN setup for media and static assets
• Load Balancer preparation
• Architecture ready for Auto Scaling
The system must be structurally prepared for progressive growth without critical performance degradation.
Professional UI Upgrade
• SaaS-level visual refinement
• Improved typography and hierarchy
• More professional dashboard structure
• Improved financial flow presentation
• Full visual consistency between Web and PWA
• Refined mobile experience
This is not a full redesign.
It is a professional elevation of the existing interface.
Mandatory Proof of Work Methods
To prevent superficial or fraudulent delivery:
• Daily GitHub commits are mandatory
• Small, atomic pull requests only
• No offline work allowed
• Active daily communication required
• Technical report of implemented changes
• Clear evidence of code optimization
• Before and after load test comparison
• Video demonstration of implemented improvements
Work without technical proof will not be accepted.
Acceptance Criteria
• System stable under moderate load
• Architecture prepared for scalability
• Professional SaaS-level interface
• No freezing or critical latency
• Delivery validated through objective testing
Requirements
Senior-level engineers only.
Proven experience in:
• Laravel
• AWS
• Performance tuning
• Scalable architecture
• SaaS-level UI refinement
