📌 Last project: n8n AI agent for Knight Frank, an Australian real estate firm. Their team was manually answering email queries like "any properties available on Eagle Street?" by searching an Excel sheet built from monthly PDF reports. I replaced the whole thing with an n8n workflow: OCR pulled listings from PDFs in Dropbox, embeddings went into a pinecone vector database, incoming emails got matched against it, and OpenAI wrote the reply. Shipped in three weeks. Cut manual query handling by over 98%. Tech stack: n8n, OpenAI, RAG (Retrieval-Augmented Generation), Pinecone, OCR, I'm an AI Engineer with 4 years of industry experience who builds AI agents, voice agents, chatbots, and automations that run in production. 🔧 Other recent work: Complete Luxe Cleaners Voice Agent: Takes inbound calls, answers service questions, books appointments straight into the calendar, and drops leads into HubSpot. Built with Retell AI, Twilio, HubSpot, Google Calendar, and n8n. End-to-end n8n Sales Agent: Captures leads into GoHighLevel, writes AI-personalised first-touch emails, runs follow-up sequences, and updates pipeline status in real time. Tech stack: n8n, OpenAI, GoHighLevel, Gmail, Airtable. SyllabusSync.ai: Students juggling multiple course syllabi were missing deadlines because assignments and exam dates were buried in PDFs. I built an AI tool that extracts those dates and auto-syncs them to Google Calendar with reminders. 10,000+ students using it. Tech stack: OpenAI API, Next.js, NestJS, Supabase, AWS, Stripe. 🛠 Stack I use most: Retell AI, Vapi, n8n, Make, GoHighLevel, OpenAI, Claude, LangChain, LangGraph, Pinecone, ChromaDB, Twilio, HubSpot, Next.js, Node.js. If you need to build an AI agent, voice agent, RAG-based assistant, or automate a business workflow with AI, I can help you design and deploy a scalable, production-ready solution.

It worked perfectly in testing. Then a caller with a heavy accent asked a question while their dog barked in the background, and the whole thing collapsed. That project taught me something most AI developers learn too late: the demo is 10% of the work. The other 90% is everything that can go wrong - bad audio, CRM timeouts, users who say "um" fourteen times, edge cases nobody warned you about. Now I only build AI that handles the chaos. 𝗪𝗵𝗮𝘁 𝗜'𝘃𝗲 𝗯𝘂𝗶𝗹𝘁 𝗤𝗮𝗹𝗶𝗳𝗔𝗜 takes 40+ real estate calls daily. Not test calls - actual leads, live conversations, 92% intent accuracy measured across thousands of interactions. Built on VAPI with ElevenLabs voice, GoHighLevel CRM sync, and Google Calendar booking. It qualifies buyers, handles objections, and hands off to human agents without dropping context. 𝗣𝗮𝗽𝘆𝗿𝘂𝘀 answers research questions across 15,000+ academic papers. Hierarchical chunking, hybrid search with pgvector, Cohere reranking, and cited answers. It says "I don't know" when retrieval confidence is low. Researchers trust it because it doesn't make things up. 𝗘𝗮𝘀𝘁𝗹𝗮𝘄 searches 300,000+ Pakistani court judgments. Elasticsearch for filtering, semantic search for intent, FastAPI backend serving 200+ concurrent users. Lawyers use it every morning. 𝗔𝗜 𝗙𝗿𝗮𝗻𝗸 generates legal documents with jurisdiction-aware retrieval. 700+ documents created with proper citations pulled from the right statutes. React frontend, Python backend, pgvector for legal precedent matching. 𝗦𝘁𝗮𝘆𝗦𝗾𝘂𝗶𝗿𝗲 handles hotel reception calls - booking inquiries, room availability, guest requests. Retell for voice, n8n workflows for automation, webhook integrations with property management systems. 𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸 I take on Voice AI agents, RAG systems, and AI MVPs. I'm useful when you're past the "exploring AI" phase and need something deployed. Less useful if you're still figuring out whether AI makes sense - though I'm happy to tell you if it doesn't. Most of my projects are $2K–25K and take 2–6 weeks. I don't disappear mid-project, I document everything, and I build with handoff in mind so you're not dependent on me forever.

I help founders and product teams create from scratch, build MVPs, rebuild, and scale digital products through clean development, stable and scalable architecture, and smart technical decisions. I’m a full-cycle product strategist and founder of Cadabra Studio, where my team creates websites and mobile app, rescues broken SaaS platforms, fixes unstable MVPs, and rebuilds products that are hard to maintain, slow, or failing to scale. With 10+ years of experience working with mobile apps, SaaS, marketplaces, and complex web/mobile systems, I understand where products usually break: messy codebases, poor architecture, performance issues, missing documentation, and rushed integrations. That is why, we combine engineering, product logic, and UX thinking to deliver solutions that are not only functional but reliable, maintainable, and ready for scaling. What my team and I do best: • MVP development (web + mobile) • SaaS platfrom build or rebuild • Codebase audit and technical recovery plans • Refactoring and architecture redesign • API development and third-party integrations • Performance optimization and bug fixing • Backend + database design for scalability (Node.js, Python, PHP) • Front-end development for desktop (React / Vue / Angular) • Native app development (Swift for IOS, Kotlin for Android) • Cross Platform app development (Flutter/FlutterFlow, ReactNative) • AI-powered development/Vibe coding/no code development (Cursor, Claude, Lovable, Replit, Base44) • Secure development and deployment support • Product rebuilds from legacy systems • AI-powered features and integrations I strongly believe every development decision must support one goal: product stability and predictable growth. That’s why we start with a diagnosis, not assumptions. Every project begins with a free technical consultation, where we review your product situation and define what’s blocking performance, speed, usability, or growth, and what the most efficient recovery or rebuild path should be. If your product needs a trusted long-term technical partner - we can help. With respect, Anastasiia (Stacy) CEO at Cadabra Studio /UX Trauma Center

I build AI-enabled systems for Healthcare Providers, Legal Support Firms, Operations-heavy Businesses, and B2B SaaS teams where workflows are complex, regulated, and have to hold up under real production load. Not AI demos. Not chatbots bolted onto existing software. Systems where AI is one carefully designed layer inside a reliable, auditable process that actually runs the business. What I Help You Do: - Design AI-enabled platforms where the AI is reliable enough to put in front of patients, lawyers, or paying customers - Ship HIPAA-grade AI systems where PHI never leaks to an LLM, audit logs are append-only at the database level, and BAAs are signed across the full sub-processor chain - Build legaltech operations platforms with AI document parsing, multi-tenant isolation enforced at the database (PostgreSQL Row Level Security), and AI that never modifies the legal record - Automate document workflows, intake, triage, dispatch, and internal operations with AI where it has an edge and deterministic code where it doesn’t - Develop AI-enabled SaaS products from MVP to production-ready platforms with senior architectural judgment, not just code delivery - Extend AI capability into mobile apps, web platforms, and frontend/backend systems end to end - Wire AI into no-code and low-code workflows using n8n, Make, GoHighLevel, and Zapier when those tools are the right fit - Fix and stabilize existing AI systems that are slow, hallucinating, or failing compliance reviews How I Build AI Systems That Survive Production: - Most AI projects fail because they focus on the model instead of the workflow around it. - I design systems where AI is one layer inside a reliable process: - PHI and sensitive data de-identified before anything reaches an LLM, provable from API logs - Human-in-the-loop on every AI output that touches a regulated record - AI used for unstructured-to-structured work; deterministic code for calculation and rule enforcement - Append-only audit logs enforced at the database permission level, not the application - Tenant isolation at the database, not the application - Clear fallback, error handling, and observability from day one - Every AI call logged, costed, and traceable This is what separates an AI system that ships from one that survives a HIPAA review, a court challenge, or a security questionnaire from a Fortune 500 procurement team. What You Get: - AI architecture that holds up under regulatory scrutiny and senior technical review - Systems that turn hours of manual work into minutes without losing control - Clean code your team can maintain, with documentation a senior engineer can read in one sitting - Senior-level judgment on where AI fits, where it doesn’t, and what to build vs. buy - Real business impact (time saved, workflows automated, compliance posture strengthened) Core Stack for AI-Enabled Systems: AI and orchestration: OpenAI, Claude, RAG pipelines, LangGraph, vector databases (Pinecone, pgvector) Backend: Python (FastAPI, Django), Node.js Frontend: Next.js, React, TypeScript, React Native (mobile) Data: PostgreSQL with Row Level Security and pgcrypto, Redis, APIs, integrations (Stripe, Twilio, CRM systems, EHRs via FHIR R4) No-code and low-code automation: n8n, Make, GoHighLevel, Zapier Infrastructure: AWS, GCP, Docker, Vercel, all with BAA-covered configurations for healthcare workloads Compliance fluency: HIPAA Security Rule (45 CFR §164.308, §164.310, §164.312), HITECH breach notification, FHIR R4, SMART on FHIR, BAA chain management, court-grade evidence handling for legaltech If you’re trying to put AI inside a real business and you need it to work in production, in regulated environments, at the standard a senior engineering team would actually trust, I can help you design and ship it
