Hire the Best Liveoak Technologies Liveoak Specialists

I build SaaS platforms and marketplaces end to end. An eSIM marketplace where a purchase hits a provider API and the plan lands on the buyer's device in seconds. A city transit system tracking 800+ vehicles across 200 routes in real time. Both built and shipped solo. Most projects reach me at one of three points: a founder with an MVP that needs to become a real product, a marketplace where payments and payouts have to actually work, or a codebase someone else left half-finished. What I get hired for: Marketplaces and multi-vendor platforms. Provider APIs, vendor accounts, order flow, payouts. Payments and subscriptions. 30,000+ transactions in production across projects. Stripe, PayPal, recurring billing, webhook handling with idempotency, failed payment recovery. Real-time backends. Spring Boot with WebSocket, Redis and PostGIS. Live positions pushed to clients, not polled. Business logic that does not fit a plugin. A print pricing engine that computes cost from sheet imposition instead of a lookup table. A WooCommerce distributor portal with role-based pricing and a points balance. Both live and linked below. Stack: PHP 8, Laravel 8-11, Vue 3, Nuxt, TypeScript, Java, Spring Boot 3 including reactive WebFlux, PostgreSQL, MySQL, Redis, PostGIS, Docker, REST and WebSocket APIs. DDD, Clean Architecture, CQRS. Track record outside Upwork: 40+ completed projects, 5.0 average rating. How I work: written, async, detailed updates. I tell you when something in your spec will not work before I build it, not after. Send the repo, the URL or the spec and I will tell you what I actually see in it.

Stop building just another feature. Start automating business outcomes. As a Top-Rated Full-Stack Engineer (100% Job Success) specializing in AI Automation, I bridge the gap between traditional MERN/Next.js development and cutting-edge LLM integration. I don’t just wrap APIs; I build secure, production-grade AI systems that save time, cut costs, and scale gracefully. WHY PARTNER WITH ME? 🔹 Beyond Basic Chatbots: I engineer autonomous AI Agents (LangGraph, LangChain, CrewAI, MCP) that execute complex, multi-step business logic and real-world tasks. 🔹 Data-Driven AI (RAG): I build robust Retrieval-Augmented Generation pipelines using Vector Databases (Pinecone, Supabase) so your AI answers reliably using your private data—with zero hallucinations. 🔹 Production-Ready Architecture: AI is useless if the core app crashes. I ensure seamless integration into robust Node.js and Next.js architectures with enterprise-grade security and multitenant authentication (Keycloak/SSO). 🔹 Human-in-the-Loop Safety: I implement strict guardrails and prompt security to keep your proprietary data protected and your operations reliable. CORE TECH STACK & EXPERTISE: 🧠 AI & LLMs: LangGraph, CrewAI, Custom Agent Workflows, Prompt Engineering, RAG Pipelines. 💻 Frontend: React.js, Next.js, TypeScript, UI/UX optimization. ⚙️ Backend & Databases: Node.js, Nest.js, GraphQL, PostgreSQL, MongoDB, Vector Databases. ☁️ Cloud & DevOps: Docker, Microservices, Stripe API, Keycloak, REST APIs. TYPICAL ENGAGEMENTS: ✔️ Custom AI Agents: Building multi-agent systems for lead generation, data extraction, or automated customer support. ✔️ Internal AI Knowledge Bases: Designing RAG systems to instantly query massive amounts of internal PDFs, contracts, or company data. ✔️ Legacy Modernization: Retrofitting your existing web applications with modern, AI-native capabilities. ✔️ Full-Stack Development: End-to-end development of scalable SaaS platforms from architecture to deployment. My goal is to deliver measurable ROI, not just lines of code. If you want a technical partner who communicates transparently and delivers on time, let’s talk. Send me a message to discuss your current bottlenecks, and let's map out an automation strategy that scales. --- 🚀 EXPLORE MY WORK Please view the Portfolio section below to see live interactive demos of my AI-native applications and my complete 6-year engineering showcase.

Most software projects don't fail because the code was hard. They fail because the wrong decisions got made in the first two weeks, and someone paid for that later with a rebuild. That is the part I care about most. I run Posybl, an AI-native software studio. Along the way, I've built for names like Sony, PepsiCo and Ericsson, as well as founders and small teams who just needed their idea to work. I don't only write the build. I help you pick the right path before a single workflow is created, so you spend money once instead of twice. What I build • SaaS platforms • Startup MVPs • Marketplaces • CRM and ERP systems • AI-powered apps • Internal tools • Client and staff portals • Booking and scheduling systems • Inventory platforms • Dashboards and reporting • Workflow automation • Custom web apps that don't fit a template How I build it I choose the platform and architecture based on what the product actually needs. My team and I can launch lean, integrate the right services and scale the infrastructure as the product grows: • Node.js • Next.js • PostgreSQL • Supabase • Neon • Xano • REST and GraphQL APIs • Stripe and Stripe Connect • OpenAI and Claude integrations • Twilio • Google APIs • Airtable • Make(.)com and n8n So you're not hiring "a generic AI guy". You're hiring someone who can start you lean and move you onto heavier infrastructure the day your growth demands it. Where I've worked • Healthcare • Fintech and financial services • Construction • Education • Logistics • Property • Manufacturing, and • Professional services. Real projects have included AI education platforms, Financial applications, Compliance and Document Systems, Quoting and Estimating tools, Customer portals, Inventory Management, and End-to-end automation. What every build gets, by default Secure. Scalable. Fast on mobile and desktop. Easy to maintain instead of held together with patches. And shaped around how your business actually runs, not around whatever was easiest to code. How I work I start with the problem, not the feature list. I'll pressure-test your idea, flag the risks early, recommend an architecture that won't box you in, and build something that can grow with you. A lot of my clients launch a lean Bubble MVP to validate fast, then layer in Node.js, Supabase, Postgres or custom APIs as usage climbs. The goal never changes, software that returns real business value. Founder with a raw idea, or an established team modernising old systems, either way I'm happy to talk it through. If you want a developer who pairs the technical side with commercial judgement and clear, honest communication, let's have a conversation about what you're building.
