App Not Working on Some Browsers or Devices
Your app works fine on your browser (usually Chrome) but breaks on other browsers like Safari or Firefox, or on specific devices. Features don't work, layouts break, or the app doesn't load at all.
Common Causes
- Using browser-specific APIs not supported everywhere (e.g., some CSS features in Safari)
- JavaScript syntax not supported in older browsers
- Safari has stricter cookie and storage policies that can break auth
- Mobile browsers have different viewport handling
- WebKit rendering differences causing layout issues on iOS
How to Fix It
- Test on the broken browser — open the console (F12 or equivalent) for error messages
- Check Can I Use (caniuse.com) for any APIs or CSS features your app relies on
- If Safari breaks auth, check cookie settings — Safari blocks third-party cookies by default
- Add appropriate CSS prefixes for Safari (-webkit-) and Firefox (-moz-)
- Test on actual devices, not just browser dev tools device emulation

Basel Issmail
’m a Senior Full-Stack Developer and Tech Lead with experience designing and building scalable web platforms. I work across the full development lifecycle, from translating business requirements into technical architecture to delivering reliable production systems.
My work focuses on modern web technologies, including TypeScript, Angular, Node.js, and cloud-based architectures. I enjoy solving complex technical problems and helping teams turn product ideas and prototypes into working platforms that can grow and scale.
In addition to development, I often collaborate closely with product managers, business analysts, designers, and QA teams to ensure that solutions align with both technical and business goals.
I enjoy working with startups and product teams where I can contribute both as a hands-on engineer and as a technical partner in designing and delivering impactful software.

I am a technologist and product builder dedicated to creating high-impact solutions at the intersection of AI and specialized markets. Currently, I am focused on PropScan (EstateGuard), an AI-driven SaaS platform tailored for the Japanese real estate industry, and exploring the potential of Archify.
As an INFJ-T, I approach development with a "systems-thinking" mindset—balancing technical precision with a deep understanding of user needs. I particularly enjoy the challenge of architecting Vertical AI SaaS and optimizing Small Language Models (SLMs) to solve specific, real-world business problems. Whether I'm in a CTO-level leadership role or hands-on with the code, I thrive on building tools that turn complex data into actionable value.
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)

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
It works on Chrome but breaks on Safari. Is that common?
Very common. Safari has different CSS rendering, stricter cookie policies, and some JavaScript APIs aren't fully supported. AI tools typically test only on Chrome.
Do I need to support all browsers?
At minimum, support Chrome, Safari, and Firefox — that covers 95%+ of users. A developer can identify and fix the specific compatibility issues.
