Most enterprise AI systems fail because they remain fragile, unscalable prototypes. I design and launch production-ready AI automation systems, autonomous AI agents, and secure SaaS platforms that reduce operational friction and scale with your business. Whether you need a custom multi-tenant SaaS application or human-like voice agents integrated with your existing tools, I bridge the gap between advanced LLMs and stable, enterprise-grade software. 🤖 AI Agent Architecture & Voice AI Voice AI Agents * Human-like voice agents powered by Vapi, Retell AI, and ElevenLabs * Outbound calling, appointment booking, customer support, and lead qualification Autonomous AI Agents * CRM automation * Knowledge base retrieval * Lead qualification * Internal business assistants LLM Integrations * OpenAI API * Anthropic Claude * LangChain * Vector databases (RAG) --- ⚙️ AI Workflow & Business Automation Operational Automation * Custom API integrations * Webhooks * Make (Integromat) * Zapier Data Synchronization * Secure integrations between databases, CRMs, and internal systems Business Intelligence * Automated reporting * Live monitoring * Scheduled alerts * Internal dashboards --- 💻 Full-Stack SaaS Development Platform Development * Multi-tenant SaaS applications * Web applications * Mobile applications * Admin dashboards * Client portals Core Business Systems * Stripe payment integration * Subscription management * Authentication & authorization * Role-based access control Performance & Scalability * Legacy codebase modernization * API optimization * Production scaling * Performance improvements --- If you're looking for someone who can build AI solutions that are reliable, maintainable, and ready for production - not just demos - I'd be happy to discuss your project.

Most AI SaaS MVPs fail in one of three places: they take so long to build that the market moves on, they fall over the first week real users show up, or the AI is bolted on as a demo feature instead of built into the core. I'm an AI-native full-stack developer who builds MVPs and SaaS platforms that avoid all three. The AI is load-bearing, the architecture holds up under real traffic, and v1 is built so it becomes v2 without a rewrite. I've worked on real products like Integry, a Silicon Valley integration platform that has raised multiple rounds and handles over a billion API calls a month, so scale isn't theoretical for me. And I have the shipped platforms to back it up. TopTec (Full-stack SaaS + AI voice agent): Multi-tenant home services marketplace with customer and technician mobile apps, role-based company and admin dashboards, Stripe subscription lifecycle, and an AI voice receptionist (Twilio + VAPI + GPT + MCP tools) that answers inbound calls and closes bookings autonomously, backed by n8n pipelines. Facebloom (AI + computer vision mobile): Turns a single selfie into a full skin analysis: skin type and condition detection, tone and undertone analysis, celebrity look-alike matching, and personalized product recommendations, all through a TensorFlow and Mediapipe vision pipeline. Reached Top 20 on the App Store. Fotivo (AI SaaS for ecommerce): Gemini-powered visual creation platform. Brands upload a product photo and get studio-quality marketing images, no prompt engineering. AI orchestration engine, Stripe billing, rate limiting, usage controls, and a full admin dashboard. SMFmed (Healthcare AI SaaS): AI medical records platform that turns dense clinical reports into plain-language summaries patients can actually read. Secure storage and parsing, cross-report history, and a dual-role doctor and patient portal with role-based access. Openline (AI counselling app): Relationship support platform for couples. Real-time messaging plus an AI layer that turns messy, emotional conversations into structured, constructive action plans. Heavy structured-output work under ambiguous, high-emotion input. Calling All Kids (AI voice, child-safe): AI character calling platform for kids. Children get personalized phone calls from fictional characters powered by GPT and ElevenLabs TTS, contextual to each child, age-appropriate, and consistent from one call to the next. Buff (Flutter mobile at scale): Gamified fitness app for the Buff Dudes brand. 50,000+ users in under a year, 5,000 daily active, RevenueCat subscriptions, and a scalable Node.js backend with Redis caching, Mixpanel analytics, and Sentry monitoring. ✅ How I work: I scope the MVP to what actually proves the idea, not a feature dump. I architect for v2 from day one (auth, billing, multi-tenant boundaries, REST APIs, webhook lifecycle) so you're not rebuilding after the first 1,000 users. I use AI where it earns its place: orchestration, structured outputs, computer vision, voice agents, wired into the core flow rather than bolted on as a chatbot. I also take over and fix existing builds: debugging live SaaS platforms, stabilizing buggy mobile apps, and resolving API and backend issues fast. ✅ What I build: Full-stack web apps and AI-native SaaS platforms (OpenAI, Gemini, computer vision, voice), multi-tenant architecture with Stripe billing, role-based dashboards and admin panels, backend and API development (Node.js, Express, Python, FastAPI, REST APIs, webhooks), mobile apps in Flutter for iOS and Android, AI voice agents (Twilio, VAPI, ElevenLabs) and n8n automation workflows, debugging and stabilization of live web and mobile products, and full production systems once the MVP works. ✅ Stack: - Frontend and mobile: React, Next.js, Flutter, TypeScript, JavaScript - Backend: Node.js, Express, Python, FastAPI, Firebase, REST APIs, Webhooks - AI and LLMs: OpenAI, Gemini, LangChain, RAG, structured outputs, multimodal models - Computer vision: TensorFlow, Mediapipe, ML Kit - Voice AI and telephony: Twilio, VAPI, ElevenLabs, LiveKit, Whisper - Automation: n8n, Zapier, workflow automation - Databases: PostgreSQL, Supabase, MongoDB, MySQL, DynamoDB - DevOps: AWS, Serverless, Vercel, GitHub, CI/CD, Redis - Payments: Stripe, RevenueCat, Plaid - Monitoring: Sentry, Mixpanel If you're building an AI SaaS or MVP, shipping a full-stack web or mobile product, or need an existing build fixed and scaled past launch, send me the brief. I'll tell you honestly whether I'm the right fit before we waste each other's time.

I help startups and businesses build AI-powered web applications, automate workflows, and ship production-ready software fast. 5+ years of professional experience across full-stack development, AI and LLM integration, cloud infrastructure, and DevOps. I've built SaaS platforms, RAG-based AI systems, voice AI agents, fintech backends, and scalable marketplace applications from architecture to deployment. AI & LLM Development I build real AI products, not demos. My work includes RAG (Retrieval-Augmented Generation) pipelines, AI agents, LLM-powered automation workflows, document processing systems, and chatbots with structured outputs and guardrails. I integrate OpenAI (GPT-4o), Anthropic Claude, Google Gemini, LangChain, and vector databases (pgvector, Pinecone, Qdrant) into production applications regularly. Recent AI work includes a production RAG system aggregating multi-source data and feeding structured context to Claude and OpenAI, a voice AI calling system with STT, TTS, and LLM conversation logic connected over SIP, and an AI-assisted SaaS platform using Claude for case analysis with validated JSON outputs. Full-Stack Web Development I build complete web applications from frontend to backend to deployment. I work across the MERN and MEAN stacks and am equally strong in Java Spring Boot microservices. Every system I ship is clean, documented, and built to scale. Frontend: React, Next.js (App Router), Vue.js, Angular, TypeScript, Tailwind CSS, shadcn/ui Backend: Node.js, NestJS, Express.js, Java Spring Boot, Python FastAPI Databases: PostgreSQL, MongoDB, MySQL, Redis, DynamoDB, Firebase APIs: REST, GraphQL, WebSockets, Webhooks, third-party integrations Cloud & DevOps AWS Services: Lambda, S3, EC2, ECS, RDS, API Gateway, DynamoDB, SES, Transcribe, Bedrock, SageMaker, EventBridge, CloudFormation, Secrets Manager Azure Services: App Services, AKS, Functions, Durable Functions, Data Factory, Synapse Analytics, Event Hub, IoT Hub, Blob Storage, Cognitive Services, Key Vault DevOps: Docker, Kubernetes, CI/CD pipelines, GitHub Actions, Jenkins, GitLab CI/CD, Azure DevOps, Terraform Types of Projects I Build SaaS platforms and multi-tenant applications AI automation systems and LLM-powered workflows Voice AI agents (Retell AI, Twilio, ElevenLabs, Deepgram) Fintech and payment systems (Stripe, ACH, wire transfers) Marketplace and e-commerce platforms Internal tools, admin dashboards, and CRM systems RAG pipelines and AI document processing DevOps setup, cloud migrations, and CI/CD pipelines API integrations and backend automation Why Clients Work With Me I communicate clearly and proactively. I flag blockers before they become problems. I write clean, maintainable code with documentation that future developers can actually use. I think in product terms, not just tickets, and I push back when something doesn't make business or technical sense. If you are building an AI-powered product, automating a manual workflow, scaling a SaaS platform, or need a senior developer who can own a system end to end, I would love to hear about your project.
