Legal limitations, trademark acknowledgements, lab vs. field performance boundaries, and commercial outcome disclosures for independent software engineering consulting.
INDEPENDENT CONTRACTOR NOTICE
Fajle Rabbi Choyon operates as an independent senior web designer and developer based in Uttara, Dhaka, Bangladesh. All case studies, audit tools, and project benchmarks presented on choyon.dev represent genuine engineering work executed directly for clients worldwide.
Core Web Vitals & PageSpeed Score Scope
Performance optimization audits and delivery commitments adhere to rigorous engineering standards:
- Lab vs. Field Telemetry: Google Lighthouse synthetic scores are measured in simulated network environments. Real-User Metrics (Chrome User Experience Report / CrUX) aggregate actual 75th-percentile visitor data over a rolling 28-day window across diverse mobile cellular connections.
- Post-Handover Variables: Performance metrics are guaranteed at the moment of DNS cutover on verified server configurations. Subsequent installation of unoptimized third-party plugins (e.g., bulky live chat widgets, multiple ad remarketing pixels) or migration to budget shared hosting with poor TTFB latency may degrade real-world speeds outside our control.
No Guarantee of Specific Sales or Search Placement
Engineering fast page speed, semantic HTML5, and valid Schema.org structured data provides the technical foundation for search visibility and conversion optimization. However:
- I make no representations or guarantees regarding specific revenue figures, return on ad spend (ROAS), or specific numerical keyword rankings on Google Search. Commercial success depends on market competition, product demand, client pricing strategy, advertising campaigns, and ongoing search engine algorithm updates.
