Slow Application Startup on Replit
Your app takes 30+ seconds to start, making development slow and deployments take forever. Startup time is unacceptable.
Spring Boot's autoconfiguration and component scanning cause slow initialization.
Common Causes
- Large number of beans and autoconfiguration
- Component scanning entire classpath
- Eager database connection initialization
- Loading all data on startup
- Hibernate scanning all entities
How to Fix It
Use spring-boot-starter-webflux for async. Defer non-critical beans with @Lazy. Exclude unnecessary autoconfiguration: @SpringBootApplication(exclude={...}). Move startup data loading to lazy-loaded service. Use spring.jpa.properties.hibernate.hbm2ddl.auto=validate instead of create/update. Profile startup with --debug flag.
Real developers can help you.

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)

I’m a product-focused engineer and tech leader who builds scalable systems and turns ideas into production-ready platforms.
Over the past years, I’ve worked across startups and fast-moving teams, leading backend architecture, improving system reliability, and shipping products used by thousands of users. My strength is not just writing code — but connecting product vision, technical execution, and business impact.

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.

You don't need to be technical. Just describe what's wrong and a verified developer will handle the rest.
