𝗔𝗜 𝗰𝗼𝗱𝗲 𝗯𝗿𝗲𝗮𝗸𝘀 𝗱𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝘁𝗹𝘆 𝘁𝗵𝗮𝗻 𝗿𝗲𝗴𝘂𝗹𝗮𝗿 𝗰𝗼𝗱𝗲 - it looks perfect in a demo, then hallucinates, misses an edge case, fails silently, or creates bad data the first week real users touch it. I make sure it survives that. I'm Lizaveta, a full-stack developer focused on AI-powered SaaS products, internal tools, dashboards, CRM workflows, and production-ready integrations. I build with Node.js, TypeScript, NestJS, React, Next.js, Firebase, PostgreSQL, MongoDB, Redis, REST APIs, OpenAI API, Claude API, RAG, vector search, LangChain, LangGraph, and third-party APIs. My work is usually not “just add AI.” It is making sure AI fits safely into the product: validation, fallback logic, structured outputs, confidence thresholds, monitoring, human review flows, and clean backend boundaries. 𝗪𝗛𝗔𝗧 𝗜'𝗩𝗘 𝗕𝗨𝗜𝗟𝗧 A SaaS platform serving 35,000+ businesses and processing 2.5M transactions per year - integrated an AI chatbot with ML document parsing into a live product, hardened for real user traffic rather than a controlled demo. A Series B-funded PropTech SaaS with around 100 employees - built product features inside a live microservices architecture without disrupting workflows already used by thousands of professionals. A healthcare SaaS product - built AI-assisted workflows into an existing platform, with validation logic separating deterministic checks from AI-based interpretation so failures surfaced clearly instead of silently. Marketplace and dashboard products - built merchant/admin flows, user roles, reporting, API integrations, search, product-data workflows, and back-office tools where reliability mattered more than visual polish. CRM and automation workflows - built internal tools, lead flows, customer records, webhook integrations, task automation, and AI-assisted workflows that helped teams reduce manual work without losing control of the process. 𝗪𝗛𝗔𝗧 𝗜 𝗕𝗨𝗜𝗟𝗗 𝗙𝗢𝗥 𝗬𝗢𝗨 AI features that survive production: RAG pipelines, LLM-powered agents, AI assistants, document parsing, semantic search, prompt workflows, structured outputs, fallback paths, and evaluation harnesses. Full-stack SaaS applications: Node.js, NestJS, TypeScript, React, Next.js, Firebase, PostgreSQL, REST APIs, GraphQL, authentication, role-based access, dashboards, admin panels, and background jobs. Integrations that don’t quietly fail: webhooks, third-party APIs, payment flows, CRM integrations, Firebase functions, retry logic, idempotency, error handling, monitoring, and clean logs. Backend systems for AI products: API design, database schema, queue/background processing, vector search, metadata handling, file ingestion, secure auth, cloud deployment, CI/CD, and production debugging. Dashboards and internal tools: admin panels, analytics pages, CRM views, reporting flows, moderation screens, user management, team accounts, permissions, and workflow automation. 𝗛𝗢𝗪 𝗜 𝗪𝗢𝗥𝗞 I do not overbuild. I first identify where the system can fail: bad AI output, missing data, weak API boundaries, poor auth logic, unclear user roles, broken webhooks, slow queries, or integrations without retries. Then I build the smallest reliable version that can actually ship. You get clean communication, structured delivery, realistic estimates, and production-minded engineering. 𝗖𝗢𝗥𝗘 𝗦𝗧𝗔𝗖𝗞 Backend: Node.js, TypeScript, NestJS, Express.js, REST API, GraphQL, Firebase Functions Frontend: React, Next.js, Tailwind CSS, dashboards, admin panels, SaaS UI Databases: PostgreSQL, Firebase/Firestore, MongoDB, Redis AI: OpenAI API, Claude API, LangChain, LangGraph, RAG, vector search, embeddings, prompt engineering, AI agents Cloud / DevOps: AWS, Firebase, Docker, CI/CD, GitHub Actions Integrations: webhooks, OAuth/JWT, Stripe, CRM APIs, payment APIs, third-party SaaS APIs Reliability: logging, monitoring, validation, fallback logic, retry/idempotency, testing, production debugging 𝗚𝗢𝗢𝗗 𝗙𝗜𝗧 𝗜𝗙 𝗬𝗢𝗨 𝗡𝗘𝗘𝗗 An AI feature added to an existing SaaS product. A RAG system or AI assistant that needs to work with real data. A Firebase / Node.js / TypeScript backend cleaned up or extended. A dashboard, CRM, internal tool, or admin panel built properly. A third-party API, webhook, payment, or automation flow made reliable. A developer who can think through product risk, not just close tickets.

I help founders and businesses build AI-powered SaaS products, internal platforms, and backend systems that are designed for real users, real workloads, and long-term growth. Most software projects fail because teams focus on code before understanding the business process. My approach is different: first we define the workflow, users, integrations, and operational requirements. Then I design and build the system so it remains reliable when customers, data, and usage grow. Throughout my career I've worked on scalable cloud systems, authentication platforms, SaaS products, workflow automation tools, and AI-enabled applications using AWS and TypeScript. Whether you're launching a new product, modernizing internal operations, or integrating AI into an existing platform, I can help take the project from architecture to production. How I Work I combine strong software architecture practices with modern AI-assisted development workflows to accelerate delivery without compromising quality, maintainability, or long-term scalability. AI is integrated throughout planning, implementation, testing, documentation, and code reviews where it creates a clear advantage. This allows me to move faster on repetitive engineering tasks while keeping human oversight on architecture, security, business logic, and critical technical decisions. I work with modern AI development workflows, including AI coding assistants, agent-based tooling, retrieval systems, MCP-based integrations, and AI-powered automation pipelines. However, I view these as productivity tools—not substitutes for sound engineering judgment. For clients, this typically means: • Faster development cycles • Reduced implementation costs • Better documentation and maintainability • Quicker prototyping and iteration • More focus on solving business problems instead of repetitive engineering work What I Build AI-Powered SaaS Products AI-enabled applications and platforms AI agents and workflow automation Retrieval-Augmented Generation (RAG) systems Knowledge bases and document intelligence OpenAI and Claude integrations Multi-step agent workflows Backend Systems & SaaS Architecture Node.js and TypeScript backends NestJS applications Multi-tenant SaaS platforms Scalable REST APIs Authentication and authorization systems Event-driven architectures Enterprise workflow platforms AWS Cloud & Serverless Systems I design systems that remain maintainable and cost-effective as usage grows rather than requiring expensive rewrites later.
