A passionate and detail-driven Full-Stack Developer with proven experience building scalable, responsive, and user-friendly applications. Specialized in no-code development with Bubble.io, I have delivered robust products for early-stage startups and growing ventures. On the front-end, I focus on creating elegant, efficient, and engaging user experiences.

I am a AI Solutions Developer & Architect. I design, engineer, and deploy production-grade AI systems, multi-agent architectures, and scalable SaaS platforms. I pride myself on my high energy, deep problem solving ability, and communication skills, something I offer to all clients. Building reliable AI systems requires secure data pipelines, intelligent orchestration, and resilient architecture. It also requires time, consideration, and conversation with clients. Clients know what they need, I know how to execute it, but that starts with listening, understanding, and translating the clients vision, problem, or ideas, into a technical reality. I provide both the technical leadership to design these systems and the hands-on engineering to build them. The Evidence & Results: With 8+ years of engineering and technical experience, I have built over 40 products and complex automation tools, managed teams of junior and mid-level developers, and scaled my own SaaS platform to 50,000+ users processing $4M+ in transaction volume. Because I actively manage my own portfolio of products in the market, I align deep technical execution directly with commercial realities. Recent deployments include: 1. AI Infrastructure: Architected an AI routing system using local LLMs, embeddings, as well as agentic systems to support ongoing maintenance and management without human intervention. 2. Agentic Systems: Engineered scalable conversational AI assistants and deployed custom MCP (Model Context Protocol) servers for advanced LLM tool calling. 3. Backend Architecture: Replaced the entire backend tech stack for an agency, delivering a bespoke product saving tens of thousands annually. 4. Workflow Optimization: Solved year-long CRM and complex operational bottlenecks for a B2B client in under four weeks. 5. Built a SaaS product and native mobile app that was showcased at an OpenAI event in Sydney, Australia (Builder Lounge). How I Help: I step in when individuals or companies need an expert to own the technical product roadmap, audit existing systems, or build complex AI pipelines from scratch. I do not build fragile prototypes; I architect systems that hold up under real-world load. Technical Depth and Experience: 1. AI & Systems Architecture: Multi-Agent Systems, Custom MCP Servers, LLM Tool Calling, RAG, Vector Embeddings, Solutions Architecture. 2. Languages & Frameworks: Python, TypeScript, JavaScript, Next.js, React, PHP. 3. Backend & Data: PostgreSQL, MySQL, REST APIs, BigQuery, Upstash, Database Migration. 4. Infrastructure & Ops: AWS, CI/CD, Product Management. 5. Product Development: Product design, development of MVPs, real world products, prototyping, and database design for actual SaaS product launches. I would welcome the opportunity to speak with you about your project on a free consultation call, or via direct message. Thanks, Nick

I've built and launched multiple SaaS products myself. As a founder who needed them to work, scale, and grow with the business. That background changes everything about how I approach a project. I show up as a product thinker who has been on your side of the table. I understand what a system needs to support real users, real operations, and real growth. And I bring that perspective into every engagement from day one. I find the smartest structure before complexity sets in. I simplify what others overbuild. I spot the opportunities that aren't in the brief yet. And then I build it. What I'm best at: - Multi-tenant SaaS platforms with clean role separation and solid data architecture - Stripe and Stripe Connect Express including subscriptions, webhooks, Connect onboarding, and seat reservation logic - Discovery and Blueprint engagements where we design the right system before the build starts - Platform audits and codebase takeovers where an existing product gets restructured and brought to its next level - Marketplace and multi-role systems where permissions and workflow logic are the core challenge - Operational platforms with compliance requirements, audit logging, and backend-heavy workflows I build with the right tool for the problem: Bubble for complex workflow-heavy SaaS products where speed and flexibility matter. Next.js, TypeScript, Supabase, and Vercel for code-based products where the stack calls for it. The tool follows the problem, not the other way around. Products I've designed and built: - A multi-location hospitality operations platform with reservation logic, capacity rules, Stripe billing, and operator dashboards, live and running in production - A multi-tenant water testing laboratory platform with five distinct user roles, strict data separation between tenants, audit logging, and compliance workflows, built for real daily operations - A sports course marketplace architecture with a block-based lesson generator, Stripe Connect Express trainer onboarding, and seat reservation logic, delivered as a paid Blueprint engagement before any build started - A brand review SaaS with structured feedback collection, a community discussion layer, AI-powered summaries, and an embeddable trust widget, self-built and operated - A curated AI film platform with moderation workflows, creator dashboards, and admin curation tooling, self-built and operated How we work together: Before we build anything, we design it together. A short Blueprint or Discovery milestone gives you a clear architecture, a realistic budget, and a solid foundation that grows with your product. You get a clear picture of exactly what you're building, how much it costs, and why every decision was made. I bring honest product thinking, sharp architectural judgment, and the kind of out-of-the-box perspective that comes from building your own products. I ask the right questions, find the smarter path, and make sure every decision serves the product long term. If you want a senior architect who thinks the system through, designs it properly, and then builds it with you, that's exactly what I do.

I help companies migrate their Bubble applications to scalable, code-based architectures on AWS — progressively, without downtime, and without rebuilding from scratch. I'm a software developer with 5 years of experience across Bubble and traditional code (Node.js, React, Python). Right now I work daily on exactly this problem, in two production environments: 🏭 VEXTA — an industrial AI platform for critical assets in Oil & Gas. I build and maintain a hybrid Bubble + code architecture: Bubble frontend connected to multiple external backends, heavy third-party integrations, and enterprise SSO (Login with Microsoft / Azure AD). This is the hybrid model I recommend to most clients as the first migration step — and I run it in production every day. ⚡ Enexus (Panama) — as part-time Technical Lead, I drive architecture decisions and the progressive migration of a production Bubble app to microservices on AWS. Selected results: ✅ Cut critical dashboard load times from 20s to 5s (75% faster) through stress testing and optimization ✅ Designed and built a custom backup & data distribution service outside Bubble — moving critical data functionality to independent infrastructure ✅ Led penetration testing and security hardening of the production app ✅ Trained the internal dev team in AI-assisted development workflows Why this matters to you: Bubble is excellent for launching fast, but as your product grows you hit its limits — performance, rising costs, scalability, vendor lock-in. Because I work on both sides every day, I know how to plan migrations that keep your business running while your stack evolves: one service at a time, with your app fully functional until each piece is safely replaced. 🔁 What I can do for you ✅ Migration audit & roadmap: an honest assessment of what to migrate, in what order — and what should stay in Bubble ✅ Hybrid architectures: Bubble frontend + code backend (the proven first step — I run one in production) ✅ Progressive migrations: rebuilding Bubble workflows as services and APIs while your app keeps running ✅ AWS infrastructure: Lambda, ECS, S3, RDS, API Gateway, CloudFront ✅ Database migration from Bubble to PostgreSQL / MongoDB ✅ Enterprise integrations: Microsoft/Azure AD SSO, Stripe, WhatsApp, CRMs, custom APIs ✅ Performance, security & scalability work on existing Bubble apps (you don't need to migrate to work with me) Also experienced with: MERN stack, Python, AI integrations (OpenAI, Claude, RAG systems), and automation with n8n & webhooks. 🛡️ How I work Migrations fail from poor process, not poor code. Every project with me includes: a staging environment for testing before anything touches production, a rollback plan for each migrated component, weekly progress updates with working demos, and full documentation and handover — your team owns everything I build. Availability: 15-20 hours per week — ideal for migration roadmaps, progressive migrations, and ongoing optimization of production apps. If your Bubble app is hitting its limits — slow pages, rising costs, features you can't build, enterprise clients asking for SSO — send me a message. I'll tell you honestly whether migration makes sense for your case, and give you a clear plan if it does.
