I build and stabilize AI automation, agents, and full stack SaaS products that need to work reliably in production, not just in demos. I’ve shipped and scaled systems for founders from Y Combinator, Founders Factory, FutureLabs, and Republic of Work. Founders I’ve built with have gone on to raise €2M+, and my AWS/serverless work ranks in the top 0.2% for DevOps. A few results: ⚡ Multi-tenant SaaS with 28% faster integrations ⚡ Serverless system running under 200ms latency at 10K+ users ⚡ AI RAG system improving support efficiency by 45% ⚡ Next.js migration reducing hosting costs by 15% ⚡ SaaS MVPs shipped to production, with founders raising after launch A lot of products today get built quickly with Cursor, Lovable, Bolt, Claude Code, or an early freelance team. Then real users arrive. That’s when the problems show up: messy code, fragile backends, AI features that worked in the demo but fail in production, scaling bottlenecks, unreliable automations, and rising AWS costs. I help turn that into a production-ready system with clean architecture, a solid backend, reliable AI behavior, and room to scale. I also build new products properly from idea to MVP to production. What I can help with: * AI agents, chatbots, and AI voice agents * Workflow automation and business process automation using n8n, Make, Zapier, and APIs * Production RAG, LLM, and knowledge-based systems * Full-stack SaaS development with Next.js, React, Node.js, TypeScript, JavaScript, and Python * Backend systems, REST APIs, third-party integrations, and multi-tenant architecture * PostgreSQL, Supabase, Stripe, AWS, serverless, performance, and cost optimization * Stabilizing fragile or AI-built MVPs before they become technical debt How I work: We can start small. Send me your app URL, repo, or brief with a short note on the problem. I’ll review the likely bottlenecks, scaling risks, reliability issues, and what I would fix first before you commit to anything bigger. From there, I can take technical ownership of the build: architecture, backend, integrations, AI systems, delivery, and the parts that usually stall. I work best with: * Funded startups starting with or moving beyond MVP * SaaS teams hitting scaling, reliability, or cost issues * Founders who want a senior engineer to take ownership, not just ship tickets I’m probably not the right fit if you’re looking for the cheapest possible build. I’m a fit when the product matters, users depend on it, and it has to work. Tech I work with often: Python, JavaScript, TypeScript, React, Next.js, Node.js, AWS, Supabase, PostgreSQL, Stripe, serverless, OpenAI, Claude, Gemini, RAG, LangChain, AI agents, n8n, Make, Zapier, automation, and APIs. If your product was built fast and now needs to work properly, or you want it built right from the start, send me the repo, app, or brief, and I’ll tell you what I’d fix first.

Most AI SaaS ideas look simple in the beginning. -Connect an AI API. -Build a few screens. -Add login. -Add payments. -Launch. But once real users enter the picture, the product needs much more than a quick demo. -The dashboard has to feel clean. -The backend has to be reliable. -The AI feature has to work with real data. -Subscriptions need to be handled properly. -Users need accounts, roles, admin controls, and a smooth experience from day one. That is where I help! I’m Haris Chandio, a Full-Stack AI SaaS Developer with 5+ years of experience building SaaS platforms, dashboards, backend systems, and AI-powered tools.

I build Healthcare SaaS products for health-tech startups — HL7/FHIR integrations, HIPAA-compliant platforms, and AI-assisted workflows. It's a tricky space. The tech has to work, and it has to be compliant. I've learned to do both. Most developers can build a web app. Far fewer understand what it means to build one that handles protected health information, integrates with legacy EMR systems over HL7 v2, stays compliant under HIPAA, and still ships on a startup timeline. That's the gap I fill. WHAT I BUILD → HL7 v2 and FHIR R4 integration pipelines — connecting EMR systems, patient portals, labs, and third-party health APIs that weren't designed to talk to each other. I've handled ADT, ORM, ORU, and SIU message types, and built the error handling and audit logging that compliance requires. → HIPAA-compliant SaaS platforms — multi-tenant architecture with proper access controls, role-based permissions, data encryption at rest and in transit, and audit trails. Not bolted on at the end — built in from the start. → AI-assisted clinical and admin workflows — OpenAI and LLM integrations that actually make sense in a healthcare context. AI features that surface the right information, reduce manual data entry, and fit into how clinical teams actually work. Nothing added just because it's trendy. → EMR and EHR API integrations — connecting platforms like Epic, Cerner, or custom-built systems to modern SaaS products via FHIR R4 APIs and custom middleware. → Full SaaS infrastructure — Stripe billing, subscription management, multi-tenancy, onboarding flows, admin dashboards, real-time reporting, and the backend APIs that tie everything together. MY STACK Backend: .NET Core (ASP.NET Core, Entity Framework, C#), Node.js, NestJS Frontend: React, Next.js, TypeScript Cloud: Microsoft Azure, AWS Databases: PostgreSQL, SQL Server, MongoDB Integrations: OpenAI API, Stripe, Twilio, third-party health APIs DevOps: Docker, CI/CD pipelines, Azure DevOps HOW I WORK I've worked with early-stage startups building from scratch and with established teams adding features to existing platforms. Both are different, and I'm comfortable with both. For early-stage work, I move fast, ask the right questions upfront, and build things that can scale — not just things that work today. For existing codebases, I take time to understand what's there before touching anything. I don't take every project. If the scope isn't clear, the timeline isn't realistic, or the fit isn't right technically, I'll say so before we start rather than halfway through. That's saved a lot of clients from painful projects. WHO I WORK BEST WITH Health-tech startups building their first SaaS product or a new feature set. Founders who have validated their idea and need a developer who understands both the engineering and the regulatory layer. Teams that want clear communication, honest timelines, and work that doesn't need to be redone. If your project sounds like what I described above, I'd be happy to jump on a quick call. I charge $5 for a 30-minute intro — just to make sure we're aligned before either of us commits to anything.
