Sobre este Serviço
Headline: Stop fighting your legacy code. Start scaling your product.
Are you stuck with a slow, outdated .NET Core 2.1 or Angular 8 application? Or are you ready to launch a high-performance AI SaaS that won't crash under load?
I am a Senior Full-Stack Engineer with a track record of engineering platforms like Cargors and Homereach, scaling them to 300k+ sales with 99.9% uptime. I don't just write code; I build production-ready systems.
What I specialize in:
- Legacy Migrations: Seamlessly upgrading .NET Core to .NET 8 and Angular 8 to Angular 21.
- Modern SaaS Stack: Next.js, Vercel AI SDK, Tailwind CSS, and shadcn/ui.
- Backend Discipline: High-performance Node.js, BullMQ/Redis worker queues, and PostgreSQL architecture.
- Headless CMS: Expert-level integration with DatoCMS, Contentful, and Netlify routing.
Why choose me?
- Architecture First: I focus on memory management, idempotency, and clean separation of concerns.
- Technical SEO: Expert in fixing soft 404s and complex Netlify redirect logic.
- Proven Experience: I've built for Logistics, PropTech, and AI-Recruitment industries.
I do not provide "quick hacks." I provide structured, deliberate engineering

Perguntas frequentes
What kind of projects have you worked on in the past?
I have a proven track record of engineering high-traffic platforms like Cargors (Logistics) and Homereach (PropTech). My work involves building systems that handle over 300k+ transactions with 99.9% uptime, focusing on robust backend architecture and seamless frontend experiences
Do you work with both modern stacks and legacy systems?
Yes. I specialize in both building new AI-native SaaS platforms (Next.js, Node.js, Vercel AI SDK) and modernizing legacy enterprise applications (specifically migrating .NET Core to .NET 8 and Angular 8 to Angular 21).
My site has "Soft 404" errors and SEO routing issues. Can you fix this?
Absolutely. I specialize in Technical SEO for headless architectures (DatoCMS, Contentful). I can refactor your Netlify/Vercel edge routing and client-side logic to ensure your server returns true HTTP status codes (200, 404, 301), which is critical for search engine indexing.
Can you handle high-load backend tasks like image processing or OCR?
Yes. I am an expert in worker queue architectures using BullMQ, Redis, or RabbitMQ. I implement deterministic hashing, idempotent logic, and memory-efficient background processing to ensure your main API remains responsive even under heavy loads
Which databases and hosting platforms do you prefer?
For performance and scalability, I typically work with PostgreSQL (Neon, RDS) or MS SQL Server. For hosting, I am proficient in Vercel, Netlify, Azure, and AWS, depending on whether your project is a lightweight SaaS or a heavy enterprise application
Will the code be documented and easy for my team to maintain?
High-quality code documentation is a standard part of my delivery. I follow Clean Code principles and provide a "Maintenance Map" or "Cheat Sheet" for non-technical founders, so you can update content or manage the site without needing a developer for every small change
How do you handle project communication?
I believe in transparency and structure. I provide daily written updates and work within defined sprint cycles. You will always know exactly what has been completed, what is in progress, and if there are any technical risks we need to address early
Do you offer post-launch support?
Yes. Every project includes a 14-day post-launch support period to fix any unexpected bugs. For larger SaaS platforms, I also offer ongoing maintenance packages to handle security updates and feature scaling.
Should I message you before placing an order?
Yes, please! Every technical project has unique requirements. A brief 5-minute chat allows me to audit your current stack or requirements and provide an accurate quote, ensuring we choose the right architecture for your business goals.
