𝐒𝐭𝐫𝐮𝐠𝐠𝐥𝐢𝐧𝐠 𝐭𝐨 𝐒𝐜𝐚𝐥𝐞 𝐘𝐨𝐮𝐫 𝐒𝐚𝐚𝐒, 𝐍𝐚𝐢𝐥 𝐂𝐨𝐦𝐩𝐥𝐞𝐱 𝐏𝐚𝐲𝐦𝐞𝐧𝐭𝐬, 𝐨𝐫 𝐓𝐮𝐫𝐧 𝐚𝐧 𝐌𝐕𝐏 𝐈𝐧𝐭𝐨 𝐚 𝐏𝐫𝐨𝐝𝐮𝐜𝐭 𝐓𝐡𝐚𝐭 𝐂𝐚𝐧 𝐀𝐜𝐭𝐮𝐚𝐥𝐥𝐲 𝐒𝐜𝐚𝐥𝐞?
Over the last 6+ years, I've helped startups and growing businesses build SaaS platforms, Stripe-powered products, marketplaces, healthcare systems, logistics software, and AI-powered applications.
Today, getting an MVP live is easier than ever. 𝐁𝐞𝐭𝐰𝐞𝐞𝐧 𝐍𝐞𝐱𝐭.𝐣𝐬, 𝐒𝐮𝐩𝐚𝐛𝐚𝐬𝐞, 𝐕𝐞𝐫𝐜𝐞𝐥, 𝐎𝐩𝐞𝐧𝐀𝐈, 𝐋𝐨𝐯𝐚𝐛𝐥𝐞, 𝐑𝐞𝐩𝐥𝐢𝐭, 𝐁𝐨𝐥𝐭, 𝐚𝐧𝐝 𝐀𝐈 𝐜𝐨𝐝𝐢𝐧𝐠 𝐭𝐨𝐨𝐥𝐬, 𝐟𝐨𝐮𝐧𝐝𝐞𝐫𝐬 𝐜𝐚𝐧 𝐦𝐨𝐯𝐞 𝐢𝐧𝐜𝐫𝐞𝐝𝐢𝐛𝐥𝐲 𝐟𝐚𝐬𝐭.
The challenge usually starts after launch.
𝐔𝐬𝐞𝐫𝐬 𝐚𝐫𝐫𝐢𝐯𝐞. 𝐏𝐚𝐲𝐦𝐞𝐧𝐭𝐬 𝐬𝐭𝐚𝐫𝐭 𝐟𝐥𝐨𝐰𝐢𝐧𝐠. 𝐃𝐚𝐭𝐚 𝐠𝐫𝐨𝐰𝐬. 𝐑𝐞𝐩𝐨𝐫𝐭𝐢𝐧𝐠 𝐛𝐞𝐜𝐨𝐦𝐞𝐬 𝐬𝐥𝐨𝐰. 𝐍𝐞𝐰 𝐟𝐞𝐚𝐭𝐮𝐫𝐞𝐬 𝐛𝐞𝐜𝐨𝐦𝐞 𝐡𝐚𝐫𝐝𝐞𝐫 𝐭𝐨 𝐬𝐡𝐢𝐩. 𝐓𝐞𝐜𝐡𝐧𝐢𝐜𝐚𝐥 𝐝𝐞𝐛𝐭 𝐬𝐭𝐚𝐫𝐭𝐬 𝐚𝐜𝐜𝐮𝐦𝐮𝐥𝐚𝐭𝐢𝐧𝐠, 𝐚𝐧𝐝 𝐬𝐮𝐝𝐝𝐞𝐧𝐥𝐲 𝐭𝐡𝐞 𝐌𝐕𝐏 𝐭𝐡𝐚𝐭 𝐰𝐨𝐫𝐤𝐞𝐝 𝐩𝐞𝐫𝐟𝐞𝐜𝐭𝐥𝐲 𝐟𝐨𝐫 𝟏𝟎𝟎 𝐮𝐬𝐞𝐫𝐬 𝐬𝐭𝐫𝐮𝐠𝐠𝐥𝐞𝐬 𝐰𝐢𝐭𝐡 𝟏𝟎,𝟎𝟎𝟎.
That's the stage where I usually get involved.
I work with founders who already have an idea, an MVP, or an existing product and need help making it secure, scalable, and maintainable for the long term.
A large part of my work revolves around SaaS architecture, Stripe billing systems, marketplaces, AI integrations, database performance, reporting systems, and multi-tenant applications.
On the payments side, I've worked extensively with Stripe Subscriptions, Stripe Connect, Payment Elements, ACH payments, marketplaces, usage-based billing, webhooks, invoicing, subscription lifecycle management, and complex revenue workflows.
On the SaaS side, my core stack includes Next.js, React, TypeScript, Supabase, PostgreSQL, Redis, .NET, C#, AWS, Azure, and Vercel. More importantly, I understand how these technologies fit together to create products that can continue growing without becoming difficult or expensive to maintain.

• Built a multi-tenant advertising and digital signage SaaS platform similar to Google Ads, allowing businesses to manage campaigns, banners, targeting rules, scheduling, analytics, and reporting. The platform processes millions of records while keeping dashboards and reports highly responsive through optimized database architecture, aggregation strategies, and caching.
• Spent 3+ years helping build a large-scale logistics platform used by delivery operations across the UK. The system includes route optimization, order management, driver mobile applications, proof of delivery, real-time tracking, customer notifications, support ticketing, invoicing, reporting, and operational workflows.
• Designed and implemented Stripe-powered subscription platforms and marketplace payment systems, including recurring billing, usage-based pricing, ACH payments, automated payouts, Stripe Connect onboarding, subscription lifecycle management, and webhook-driven automation.
• Built AI-powered solutions using OpenAI, AI agents, RAG systems, document processing workflows, intelligent assistants, and business automation systems that reduce manual work and improve operational efficiency.
What clients appreciate most is that I don't simply implement tickets.
I spend time understanding the business behind the product.
How customers sign up. How revenue flows. What should be automated? How permissions work. What happens when usage grows? Where the risks are. And how to avoid expensive mistakes before they happen.
That business-first approach allows me to make better technical decisions and build products that continue working as the company grows.

Top Rated Plus Full-Stack Developer with 12+ years of experience building SaaS platforms, internal business systems, dashboards, customer portals, and Stripe subscription products using React, Next.js, Node.js, TypeScript, PostgreSQL, and AWS.
I work with startups, SaaS companies, and growing businesses that need more than a basic website. My focus is on building software products and business platforms that improve workflows, reduce manual work, and give teams a system they can actually rely on as they grow.
Whether you’re launching a new SaaS product, building an internal operations platform, replacing spreadsheets and manual processes, creating a subscription-based application, or integrating AI into an existing product, I can help take it from planning to production.
RECENT PROJECT EXPERIENCE
Healthcare SaaS Platform (AFH Homes)
Built a HIPAA-compliant operations platform for Adult Family Homes that centralized admissions, onboarding, compliance workflows, incident reporting, audit trails, document generation, e-signatures, and multi-facility management. The system replaced fragmented manual processes and created a scalable operational foundation for long-term growth.
AI Healthcare SaaS Platform (NeuroCode MDM)
Led the end-to-end development of an AI-powered SaaS platform that helps physicians and medical coders review clinical documentation against AMA E/M guidelines, generate CPT E/M and ICD-10 coding recommendations, identify documentation gaps, and improve coding accuracy. I handled application architecture, AI integration, authentication, subscription logic, database design, and deployment.
Stripe Subscription SaaS Platform (Party Bands)
Designed and implemented the full Stripe subscription infrastructure for Party Bands, including Stripe Checkout, subscription management, webhook handling, renewals, cancellations, failed payment recovery, and customer billing workflows. The system was built to support recurring revenue growth with reliable payment and subscription handling in production.
WHAT I BUILD
• SaaS platforms and multi-tenant web applications
• Custom business software and internal operations systems
• CRM systems, admin dashboards, and workflow tools
• Subscription products and Stripe billing platforms
• Customer portals and self-service platforms
• AI-powered features, GPT integrations, and business automation
• Healthcare and HIPAA-conscious operational software
• API-driven applications and third-party integrations
• Startup MVPs that need to move from idea to production quickly
CORE TECHNOLOGIES
React.js • Next.js • Node.js • TypeScript • JavaScript • PostgreSQL • MongoDB • MySQL • REST APIs • GraphQL • OpenAI API • Stripe API • AWS • Docker • Authentication Systems • Role-Based Access Control (RBAC)
WHAT CLIENTS WORK WITH ME FOR
✔ Building SaaS products from idea to launch
✔ Structuring scalable backend systems and application architecture
✔ Developing dashboards, portals, and internal business tools
✔ Integrating Stripe subscriptions, billing flows, and payment systems
✔ Adding AI capabilities into products and operational workflows
✔ Improving, stabilizing, and scaling existing web applications
I don’t approach projects as isolated development tasks. I look at business goals, user workflows, system structure, scalability, and long-term maintainability before development starts. That helps me build software that is easier to operate, easier to extend, and better aligned with how the business actually works.
Over the years, I’ve worked on SaaS products, healthcare platforms, CRM systems, subscription businesses, customer portals, internal operations software, and AI-enabled applications that help teams work more efficiently and scale with less friction.
If you need a developer who can help architect, build, and scale a SaaS platform, business application, AI-powered product, Stripe-based subscription system, or internal operations platform, feel free to reach out and share the details of your project.

Bolt, Lovable, Cursor, and Claude Code get you 70% of the way there. The last 30% is where I live.
I finish and harden AI-built apps, and I build production AI from scratch. If your app demos well but falls apart once live users hit it, saves that don't stick, a data model that buckles at scale, security holes you can't see, that is what I fix. I also build the AI itself: phone and voice agents that book appointments, agentic workflows, and full Supabase and Stripe backends.
I know where these tools break because I clean it up for a living. One Lovable app owner described it as "fix one thing and five break." That traces straight to the generated backend, the data model and the save logic, not the features. Solidify that and the cascading bugs stop.
Recent work:
• AI phone receptionist for a service business. It answers and texts customers in the owner's voice, books appointments, and writes them straight into their Jobber CRM: client, job, and visit created automatically, nothing re-keyed in the morning. Built on Twilio, a voice agent, and a knowledge base of the owner's own playbook.
• Took a Lovable-built MVP to production: a creator marketplace that generated 150M TikTok views and paid out $15,000 to 200+ creators. Stripe Connect plus PayPal payouts, TikTok API, multi-tenant row-level security. Client: "Andrew got my MVP over the line and helped bring my vision to life."
• Overhauled a production voice agent for a hospitality venue handling live booking calls, then built one source of truth so non-technical staff edit a single page and both the text bot and the voice agent update from it.
• Audited a Supabase app and found 14 significant bugs, including booking records any logged-in user could read and missing security rules. Every finding came with the specific fix and why it matters.
• Stabilized a Lovable carousel app's edit and save flow so edits stick and it holds well past its first users.
How I work:
• Fixed price per milestone. You know the cost up front, there is no open meter, and you only move to the next piece once the current one is done and working.
• I use Claude Code and Cursor to ship 2-3x faster, and I verify everything the AI touches.
• Straight about tradeoffs and limits up front, especially on security work.
• I explain technical decisions in plain English. Most of my clients are not developers.
Stack: Supabase (Postgres, RLS, Auth, Edge Functions, Vector/RAG), Stripe (Connect, Subscriptions, webhooks), React, Next.js, React Native, TypeScript, Node.js, voice agents (ElevenLabs, Retell), Twilio, OpenAI and Claude APIs, n8n, Vercel.
Background: 10 years full-stack across health tech, edtech, and fintech. Taught two web development bootcamps. Top Rated, 100% Job Success, $60K+ earned.
If you built something with AI and it is almost there, send me a message. I will tell you straight what it needs, and what it does not.
