Hey everyone!

I'm a frontend developer looking to connect with people who are interested in building projects together, learning from each other, and gaining practical experience.

My main tech stack includes JavaScript, TypeScript, React, Next.js, and Tailwind CSS. I've already worked on some personal projects, but I want to challenge myself, improve my coding skills, and gain more experience building real-world applications.

I'm open to different kinds of projects, whether it's a web app, a SaaS idea, a developer tool, or something completely new. I don't have a specific idea in mind yet, so it'd be great to brainstorm ideas and decide what we could build together.

I'm looking for someone who's motivated to learn, share ideas, solve problems, and collaborate along the way. You don't need to be an expert. I'm happy to work with beginners or more experienced developers, and I'm also open to learning new technologies.

My goal isn't just to finish a project, but to learn, improve, and build something useful together.

If you're interested, feel free to comment or send me a DM. Tell me a little about yourself, what technologies you use, or what kind of projects you'd like to work on!

Looking forward to meeting some fellow developers! 🚀

Hi everyone,

I’m Carolina, a frontend-focused fullstack engineer based in Brazil, available for remote freelance projects, international contracts, and end-to-end development.

I specialize in taking complex requirements, data-heavy interfaces, and high-stakes systems and turning them into fast, reliable, production-ready products. While my core strength is deep in frontend architecture, state management, and performance, I comfortably own backend layers, APIs, data models, and server architecture when a project demands it.

Selected Experience & Background:
I Built the frontend of an internal platform for an international financial firm from scratch, which processed over $1.5M in wire transactions within its first 3 days in production. Later scaled micro-frontends with a distributed global team and worked on internal AI tool context servers.

In another project I build Node.js/Fastify APIs and MongoDB models handling thousands of daily calls with 98% uptime and sub-200ms response times, alongside Vue.js dashboards and an AI optimization engine that improved client ROAS by 35%.

Portfolio & Live Work:
You can check out my live projects, systems, and active work at caroolt-dev.vercel.app.

How We Can Work Together:
Whether you need someone to build a complete platform from scratch (design + code), modernize an existing interface, scale a high-performance frontend, or partner on backend integration, I handle projects end-to-end with clear communication and strict reliability.

Post-launch maintenance and ongoing feature evolution plans are also available.

What I Bring to the Table:

Frontend Excellence: React, Next.js, Vue.js, Nuxt.js, TypeScript, JavaScript, Tailwind CSS, Storybook, GSAP animations.

Backend & Data: Node.js, Nest.js, Fastify, REST APIs, GraphQL, PostgreSQL, MongoDB, Prisma, WebSockets.

Architecture & Production: End-to-end delivery, CI/CD, Docker, AWS, Sentry, testing (Jest, Vitest, Cypress), writing clear ADRs/RFCs.

AI & Tooling Integration: Experience working with LLM integrations, OpenAI APIs, and internal AI context servers.

If you have an opening, a product to build, or want to discuss a project scope, feel free to reach out via [email](mailto:carolinatc1405@gmail.com) or connect with me on LinkedIn.

Hey everyone,

I am an independent full-stack and mobile developer BZDevelopments. I build and launch complete web applications and mobile apps for founders and small businesses who need things shipped quickly without agency overhead.

My core stack:

- Web: Next.js 15, React, TypeScript, Tailwind CSS

- Backend and Databases: PostgreSQL, Supabase with Row-Level Security, Drizzle ORM, SQLite

- Payments and Auth: Stripe, PayPal, Better Auth, OAuth

- Mobile: Flutter for iOS and Android, focusing on offline-first architectures and local data sync

Recent production projects I have built and deployed:

- A privacy-first contract and subscription deadline tracking SaaS built on Next.js 15, Supabase, and automated email reminders.

- A modular full-stack starter kit suite with clean Drizzle ORM schemas and Better Auth session management.

- Offline-first mobile tools in Flutter (ERP, inventory, and bilingual accounting apps with local SQLite storage and receipt printing).

Pricing:

My rate is $30/hr, but for defined scopes like MVPs, prototypes, or specific features, I prefer agreeing on a flat fixed price so you know the exact cost upfront. Typical MVPs take between 10 to 20 days.

If you have a project or idea you want built, send me a DM here on Reddit. I will send over my GitHub and live project links so you can inspect my work, and we can discuss your scope.

I've been looking for job recently and got in touch with Circe (https://circecareer.com/)

Three interviews, not a single question about my tech stack. Generic ai-generated website. Telegram account of last interviewer was created at the same day when interview occurred.

The only question was, will I have problems with impersonation of other dev on interview.

The last guy I was talking to pretended to be a full stack dev, who said that me using Ubuntu is "unusual", knew nothing about virtualbox (I told him, that untrusted code will be executed only there) and sent me links to remote control malware.

Stay cautious, folks, and stay away from scammers
