Images Not Optimized Causing Large File Sizes
Images are loading large uncompressed files (5MB+). Page load is slow because image downloads are slow. High resolution images used even on mobile. No lazy loading.
Web images need optimization for format, size, and lazy loading. Unoptimized images account for >50% of page weight in many sites.
Common Causes
- Using PNG for photographs instead of WebP/JPEG
- Not resizing images to display size
- No responsive image srcset for different screens
- Loading images eagerly instead of lazy loading
- Using uncompressed raw images from design tool
How to Fix It
Use modern image formats and lazy loading:
Compress images online with TinyPNG or use build tool like imagemin.

Caio Rodrigues
I'm a full-stack developer focused on building practical and scalable web applications. My main experience is with **React, TypeScript, and modern frontend architectures**, where I prioritize clean code, component reusability, and maintainable project structures.
I have strong experience working with **dynamic forms, state management (Redux / React Hook Form), and complex data-driven interfaces**. I enjoy solving real-world problems by turning ideas into reliable software that companies can actually use in their daily operations.
Beyond coding, I care about **software quality and architecture**, following best practices for componentization, code organization, and performance optimization.
I'm also comfortable working across the stack when needed, integrating APIs, handling business logic, and helping transform prototypes into production-ready systems.
My goal is always to deliver solutions that are **simple, efficient, and genuinely useful for the people using them.**

Sage Fulcher
Hey I'm Sage! Im a Boston area software engineer who grew up in South Florida. Ive worked at a ton of cool places like a telehealth kidney care startup that took part in a billion dollar merger (Cricket health/Interwell health), a boutique design agency where I got to work on a ton of exciting startups including a photography education app, a collegiate Esports league and more (Philosophie), a data analytics as a service startup in Cambridge (MA) as well as at Phillips and MIT Lincoln Lab where I designed and developed novel network security visualizations and analytics. I've been writing code and furiously devoted to using computers to make people’s lives easier for about 17 years. My degree is in making computers make pretty lights and sounds. Outside of work I love hip hop, the Celtics, professional wrestling, magic the gathering, photography, drumming, and guitars (both making and playing them)

Vlad Temian
15+ years shipping production infrastructure for startups. Former CTO at qed.builders (acquired by The Sandbox).
Cursor ambassador and agentic tooling builder.
I've scaled systems, automated deployments, and built observability tools for AI coding workflows. I specialize in taking vibe-coded apps from broken prototype to production-ready: fixing Supabase auth/RLS, Stripe integrations, deployment pipelines, and cleaning up AI-generated spaghetti.
I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks.

Get HelpFrequently Asked Questions
What image format should I use?
WebP for modern browsers (best compression). JPEG for photos, PNG for icons/text with transparency. Use srcset for fallback.
Does lazy loading hurt SEO?
No, Google indexes lazy loaded images. Use loading='lazy' for below-fold images, eager for above-fold.
