Dependency Adding 500KB to Bundle Size
A small feature was added via npm package but bundle size increased 500KB. The feature doesn't justify the size increase. Build tools show the dependency is being included but it's rarely used, or lighter alternatives exist.
Adding the dependency solved a problem but created a new one: application loads slower for all users.
Error Messages You Might See
Bundle size warning: 500KB increase
Application load time increased significantly
Entry bundle larger than expected
Common Causes
- Package includes entire library when only one function is needed
- No tree-shaking configuration, entire package included despite partial use
- Dependency has heavy transitive dependencies (dependencies of dependencies)
- Duplicate dependencies at different versions in node_modules
- Development dependency accidentally included in production bundle
How to Fix It
Analyze bundle: webpack-bundle-analyzer, source-map-explorer show what takes space. Check package sizes on bundlephobia.com. Look for lighter alternatives. Use only needed exports: import { func } from 'lib' not import lib. Ensure devDependencies aren't bundled. Deduplicate: npm dedupe. Lazy load heavy dependencies.

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.

Full-stack developer experienced in fixing and deploying AI-generated apps from Lovable, Bolt.new, Cursor, and Replit. I specialize in debugging Supabase integration issues (auth flows, RLS policies, database connections), fixing broken deployments, resolving routing/blank screen problems, and cleaning up messy React/Vite codebases. I also build production apps with the Claude API and have shipped a Mac desktop dev tool (Nexterm from scratch. Based in Hong Kong, fast turnaround.
Jacek Rozanski
Senior PHP/Symfony developer and DevOps engineer with 20+ years of professional experience, running opcode.pl (web development agency, est. 2004).
Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month.
What I bring to AI-built apps:
- I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0
- I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture)
- I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting
- I integrate external services: payment providers, email systems, partner APIs, SSO/auth
Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code.
Based in Poland (CET timezone). Available for async work and calls during EU/US business hours.
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.**

Get HelpFrequently Asked Questions
How to analyze what's in the bundle?
Use webpack-bundle-analyzer (webpack-bundle-analyzer plugin) or source-map-explorer. Visualizes what takes space.
Should all dependencies be in package.json?
devDependencies for build tools, testing. dependencies for runtime. Never mix them.
How to reduce dependency size?
Use lighter alternatives (lodash-es instead of lodash). Lazy load: const lib = () => import('heavy-lib'). Tree-shake unused code.
