Broken integrations. Payment edge cases. Data that doesn&#8217;t line up across platforms. That&#8217;s the work I do, and I&#8217;ve been doing it for 13+ years.<\/p>\n\n<p class=\"wp-block-paragraph\">Right now I&#8217;m embedded with a German enterprise client (Shopware) as a forward-deployed engineer \u2014 gathering requirements straight from business stakeholders and shipping payment and AI-driven e-commerce features end to end. I&#8217;ve also run live demos at Shopware Community Day, so I&#8217;m comfortable talking to your customers as well as writing the code.<\/p>\n\n<h2 class=\"wp-block-heading\">What I can help with<\/h2>\n\n<h3 class=\"wp-block-heading\">1. E-commerce backend &amp; integrations<\/h3>\n<p class=\"wp-block-paragraph\">Shopware and Laravel backends, payment gateway work, multi-platform product and order syncs, marketplace APIs, and the crawler\/pipeline plumbing underneath. If two systems need to agree with each other and currently don&#8217;t, this is the one.<\/p>\n\n<h3 class=\"wp-block-heading\">2. AI features inside existing apps<\/h3>\n<p class=\"wp-block-paragraph\">Adding LLM and AI capability to software that already exists and already has users \u2014 RAG over your own documents, semantic search, AI translation, queue-based inference that won&#8217;t blow up your response times or your API bill. I built a multi-tenant AI translation platform on Laravel with DeepL integration, glossary management and version control, shipped to enterprise clients.<\/p>\n\n<h3 class=\"wp-block-heading\">3. Architecture rescue &amp; performance<\/h3>\n<p class=\"wp-block-paragraph\">Monolith-to-microservices migration, event-driven redesign with Kafka or RabbitMQ, database and query optimisation. Usually called in when something works but is too slow, too fragile, or too scary to change.<\/p>\n\n<h2 class=\"wp-block-heading\">Recent results<\/h2>\n\n<ul class=\"wp-block-list\">\n<li><strong><a href=\"https:\/\/dangnh.cf\/vi\/work\/lab-results-microservices-migration\/\">Lab results pipeline: ~3 hours \u2192 ~3 minutes.<\/a><\/strong> Led the migration of a large monolith to microservices at Diag Laboratories, a clinical diagnostics provider \u2014 with 100% accuracy in PDF generation and 99% uptime maintained throughout a live migration.

No surprise invoices.<\/li>\n<li><strong>Communication:<\/strong> I talk to stakeholders directly, in plain language, and I document technical decisions before implementing them. You will always know where things stand.<\/li>\n<li><strong>Rates:<\/strong> hourly engagements start at $50\/hour. For clearly defined scopes I prefer fixed price, so you know the number up front.<\/li>\n<li><strong>Availability:<\/strong> roughly 20 hours per week for new work.<\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading\">Let&#8217;s talk<\/h2>\n<p class=\"wp-block-paragraph\">Tell me what&#8217;s broken, what you&#8217;re building, or what you&#8217;re stuck on.
