Need AI added to your app, a workflow automated, or an MVP finished? I can help you scope it, build it, and ship it without overcomplicating the first milestone. I build AI products that survive real users, real data, and real business workflows: SaaS MVPs, AI agents, RAG systems, voice AI, and automation inside existing products. ⭐ Top Rated Plus | Top 3% of performers on Upwork ✅ 10+ years building SaaS and AI products | 100+ projects delivered ✅ AI that ships: RAG, AI agents, MCP, Voice AI, LLM integration ✅ Full stack: Next.js, React, TypeScript, Python, Node.js, PostgreSQL, AWS ✅ SaaS, MVPs, automation, fintech, healthcare, construction, legal tech, and sales products You can hire me when: - You need one AI feature added to an existing app - You want OpenAI, Claude, Gemini, or MCP integrated into your product - You need a RAG system over PDFs, documents, knowledge bases, or internal data - You want a voice AI agent for calls, bookings, lead qualification, or CRM updates - You have a workflow involving documents, calls, follow-ups, data entry, or reporting that should be automated - Your MVP is half-built, buggy, slow, or stuck before launch - You need someone to build a full SaaS product from idea to deployment I work well on both small and large projects. If the right first step is a quick audit, prototype, bug fix, integration, or one-week milestone, I will tell you that. If the project needs a full build, I can own the architecture, frontend, backend, AI layer, deployment, and documentation. The part most AI freelancers skip: AI is rarely the whole product. It usually needs a backend, dashboard, auth, billing, permissions, logs, human review, and deployment around it. I build both the AI layer and the product around it. WHAT I DO: - AI SaaS & MVP builds: idea to deployed product with auth, billing, dashboards, and AI layer - AI inside existing products: RAG, agents, MCP, LLM features, document AI, and automation - Voice AI: agents that answer calls, book appointments, qualify leads, and log to your CRM - RAG and document AI: source-grounded answers, OCR, extraction, citations, and review queues - Workflow automation: documents, follow-ups, data entry, reporting, and API integrations - Rescue & ship: half-built MVPs refactored, hardened, and launched RECENT DELIVERIES: - AI sales CRM: call transcription, follow-up automation, multi-tenant pipelines - RAG document platform with every answer cited to source - AI financial intelligence platform: open banking + accounting sync into one ledger - AI voice agents for healthcare and sales, answering real calls daily - Turnkey B2B SaaS platform for the construction industry, end to end HOW I WORK: - I start by understanding the workflow, users, data, and business goal - I suggest the smallest useful first milestone when possible - I scope clearly before code is written, so you know cost and timeline up front - I can work on focused tasks, short prototypes, rescue work, or full product builds - I work full time on Upwork with overlap for US and European business hours If you need one AI feature, a quick prototype, a stuck MVP fixed, or a full SaaS product built, send me a short description of what you have and what you want it to do. I will reply with the clearest next step, the likely scope, and the first milestone I would recommend.
