Full Stack Developer with experience building e-commerce platforms, business applications, SaaS products, and custom web solutions. I started programming at 12 and have spent the last several years working with clients ranging from small businesses to growing startups. My work began with WordPress, WooCommerce, and Shopify projects before expanding into custom applications, dashboards, API integrations, and platform development. Today, I serve as Lead Developer and Architect at ProfitJam, where I lead development of a visual funnel and website builder platform. My strongest skill is quickly understanding complex systems, identifying bottlenecks, and implementing practical solutions that move projects forward. Experience includes: • PHP • JavaScript • Node.js • MySQL • WordPress • WooCommerce • Shopify • REST APIs • Custom Dashboards • SaaS Platforms • Payment Integrations • Automation Systems Many projects I have worked on are proprietary or covered by NDA agreements. My Upwork history reflects most of my professional experience, including long-term contracts, recurring clients, and consistent 5-star feedback.

I build robust, secure, and scalable web systems. With over 6 years of background managing mission-critical databases in enterprise environments, I approach web development with a strong focus on architecture, data integrity, and performance. I don't just write code; I build reliable systems from the database up to the user interface. My Core Stack & Focus: • PHP, Python, and JavaScript (React, Next.js, Node.js) are my daily tools. • Custom Web Applications: Building fast platforms, custom dashboards, and APIs tailored to complex business needs. • Advanced WordPress & WooCommerce: Developing custom plugins, deep API integrations, and headless architectures (going far beyond basic themes). • Database Architecture: Structuring solid back-ends and hosting environments that won't break under pressure. The Automation Bonus: While my primary focus is web development, I also have deep experience with workflow automation. I run my own self-hosted n8n instances and build custom AI (LLM) integrations. If your web application needs to automate internal processes, sync data, or communicate intelligently with external APIs, I can build that seamlessly into the architecture. I value clean code, transparent communication, and delivering projects on time without the usual headaches. Let's chat about your project and how we can build it right. Send me a message.

Top Rated Full-Stack Engineer (.NET / Angular / React) — 10+ years, microservices, legacy rescue, AI-augmented delivery I’m Daniel, a Top Rated Upwork developer (100% Job Success) with a decade building enterprise systems for U.S. and UK clients and a Computer Science degree. I specialize in the parts most freelancers avoid: brownfield .NET codebases, microservices at scale, and shipping fast under legacy constraints. What I do best: Backend (.NET / C#) - ASP.NET Core 6–8, .NET Framework 4.7, WebForms, VB.NET, REST APIs, CQRS, MassTransit, Entity Framework Core, RabbitMQ, AWS (SQS/SNS/S3/Lambda), Azure (Service Bus, Storage Queues, Blob) Databases - SQL Server, MySQL, PostgreSQL Architecture - microservices (20+ services at handoff in my last enterprise role), event-driven systems, Docker, JWT auth Recent Upwork wins: 5.0★ legacy rescue, U.S. logistics client (229 hrs, $4.8K) — sole .NET developer on a WinForms VB.NET / MySQL app for ships, containers, parts, sales. Shipped features end-to-end and fixed bugs other devs had bounced off. Built AI coding agents into my workflow and tuned them for legacy VB.NET — throughput went from ~1 feature/day to 3+/day; refactors that used to take a day dropped to ~1 hour. 5.0★ microservice update — delivered on a fixed-price microservice + Angular update with the reviewer calling me “an absolute wizard.” Ongoing solo build (UK client) — full-stack PowerPoint-generation microservices app: React 18 frontend, .NET 6 API (C#, EF Core, PostgreSQL, Docker, JWT). I run it end-to-end. What makes me different Most engineers treat legacy code as something to escape. I treat it as the job. I’m also an AI-assisted developer. I work daily with Pi Coding Harness and Claude Code and have built custom extensions to make LLMs work better with legacy databases. Languages: Portuguese (native), English (C2), Spanish (fluent). Let’s talk about what you’re trying to ship.
