Is your Microsoft 365 or Azure setup messy, half-configured, or not as secure as it should be? That is what I fix. I am a Microsoft-certified cloud architect (AZ-305, AZ-104, Microsoft 365) with 15+ years in enterprise IT. I help businesses clean up, secure, and properly run their Microsoft cloud, from Intune and Conditional Access to Defender, Purview, and tenant hardening. I also build practical AI on top of that foundation, deployed securely on Azure and Microsoft 365. WHAT I HELP WITH Microsoft 365 and Intune Tenant setup and cleanup, Intune device management for Windows, macOS, iOS and Android, Autopilot, compliance policies, app protection, security baselines, Exchange Online, SharePoint, Teams, OneDrive, migrations, and license optimization so you are not paying for seats you do not need. Security and Compliance Microsoft Defender for Endpoint and Office 365, Entra ID Conditional Access, MFA, PIM, Identity Protection, Zero Trust, Microsoft Purview, DLP and eDiscovery, plus full tenant hardening: BitLocker, secure recovery keys, break-glass and admin best practice. Azure Architecture Landing zones, hub and spoke networking, Azure Firewall, Private Endpoints, Azure Virtual Desktop, hybrid identity, governance, backup and disaster recovery, and cost optimization (FinOps). AI That Does Real Work RAG chatbots and knowledge assistants, Microsoft 365 Copilot rollout and governance, custom AI apps and autonomous agents on Azure OpenAI, Anthropic Claude and Google Gemini, and document intelligence for invoices, contracts and forms. Built privacy-first and GDPR-ready, not just a demo. WHY CLIENTS HIRE ME - Microsoft-certified architect (AZ-305, AZ-104, Microsoft 365), not a generalist - 15+ years delivering Microsoft cloud, security and endpoint projects - 5-star reviews across 59 Upwork projects for Azure, M365 and Intune work - Certified across Microsoft, AWS and ITIL v4 - Outcome-driven: you get a working result and clear documentation, not a list of questions TYPICAL PROBLEMS I SOLVE "Our Microsoft 365 tenant is a mess after years of different admins." "Our Intune rollout is half finished and devices are not enrolling." "We need MFA and Conditional Access done properly for cyber insurance." "We bought Copilot but the data is not ready and nobody uses it." "We want AI in the business but it has to be secure and private." POPULAR STARTING ENGAGEMENTS - Microsoft 365 Security Review - Intune and Endpoint Health Check - Tenant Setup and Migration (Google Workspace to Microsoft 365) - Copilot Readiness and Rollout - AI Assistant or Automation Pilot I work with clients worldwide and speak English, German and Russian. Available for short fixed-scope projects, larger builds, and ongoing monthly advisory retainers. Message me with what you are dealing with and I will tell you how I would approach it.

Full Stack Developer and AI Engineer - CEO and Co-Founder of Invirial, 𝐚 𝐬𝐞𝐧𝐢𝐨𝐫 𝐭𝐞𝐚𝐦 𝐨𝐟 𝟗+ shipping B2B SaaS and Fintech products. Track record: Member since 𝟐𝟎𝟏𝟐 · 𝟏𝟎𝟎% JSS · $𝟔𝟎𝟎𝐊+ earned on this profile · $𝟒𝐌+ earned across our agency. To be clear upfront: I don’t write the code myself on every project. As Co-Founder, I scope, architect, and oversee delivery — my Full Stack Developers and AI Engineers ship. That’s why clients hire us instead of a solo freelancer: real capacity, senior oversight, and no single point of failure. 𝐖𝐡𝐚𝐭 𝐰𝐞 𝐛𝐮𝐢𝐥𝐝 Most clients come to us with one of two problems: they need a product built properly from scratch — an MVP that ships in weeks, not quarters — or they have an existing system that needs a senior Full Stack Developer or AI Engineer team to take ownership and move it forward without hand-holding. We’re a Full Stack Developer and AI Engineer team in one shop. That matters in 2026 because the line between the two has collapsed: modern SaaS products need React and Next.js on the frontend, Node and Python on the backend, and LangChain, RAG pipelines, and OpenAI or Claude integration as core features — not as a bolt-on. We own the whole stack end-to-end so you don’t have to coordinate three vendors. Our Full Stack Developers ship in: React, Next.js, Node.js, TypeScript, JavaScript, Python, Django, FastAPI, MongoDB, PostgreSQL, Supabase, Tailwind CSS, shadcn/ui, Stripe, AWS, Docker, REST APIs, third-party API integration. MERN stack and Next.js + Supabase + Stripe are our two default builds for SaaS MVPs. Our AI Engineers ship in: Python, LangChain, LangGraph, OpenAI API (GPT-4o, GPT-5), Claude / Anthropic API, RAG pipelines, vector databases (Pinecone, Chroma, FAISS, Weaviate), LlamaIndex, FastAPI, Hugging Face, fine-tuning (LoRA/QLoRA), n8n, Make. com, AWS Bedrock, Azure OpenAI, prompt engineering, AI agent development, chatbot development, and voice stack (Vapi, ElevenLabs, Twilio). We don’t do prompt-only ChatGPT wrappers. Our AI Engineers ship real agentic workflows — multi-step reasoning, tool calling, memory, guardrails, and production deployment. 𝐖𝐡𝐚𝐭 𝐰𝐞 𝐝𝐞𝐥𝐢𝐯𝐞𝐫 Whether you need a React developer for a SaaS dashboard, a MERN stack developer for a full product build, an AI agent developer for a multi-agent system, a generative AI engineer for a RAG chatbot, or a Next.js developer to migrate from WordPress or Bubble — we have the right senior on the team for it. Common deliverables: B2B SaaS MVPs from scratch, Fintech platforms with Stripe and compliance-aware architecture, RAG chatbots and knowledge-base assistants, AI automation with n8n + Claude, AI voice agents, admin dashboards with auth and RBAC, no-code-to-code migrations (Bubble/Lovable/Framer → coded stack), and ongoing engineering for products in growth. Recent Full Stack Developer and AI Engineer projects A snapshot of the project archetypes our team ships most often: 🔘 Fintech SaaS platforms — Next.js + Supabase + Stripe builds with subscription billing, KYC flows, role-based access, and compliance-aware architecture. Senior Full Stack Developer–led. 🔘 RAG chatbots and knowledge-base assistants — production-grade retrieval pipelines built by our AI Engineers using LangChain, Pinecone, and OpenAI or Claude, with guardrails, source citations, and LangSmith evaluation in place from day one. 🔘 AI agent and agentic workflow systems — multi-agent architectures using LangGraph, OpenAI Agents SDK, or n8n + Claude for lead generation, CRM enrichment, and internal operations automation. Built by AI Engineers who’ve shipped agents in production, not just demos. 🔘 B2B SaaS MVPs from scratch — full-cycle Full Stack Developer builds covering product architecture, React/Next.js frontend, Node or FastAPI backend, payment integration, and AWS or Vercel deployment. Designed for clients who need to launch fast and scale without a rebuild. 🔘 AI-augmented Full Stack rebuilds — taking an existing B2B SaaS or Fintech product and adding LLM-powered features (chat with your data, AI copilots, smart automation) through our combined Full Stack Developer + AI Engineer workflow. The hybrid build is what we do best. Why clients pick our Full Stack Developer and AI Engineer team over a solo freelancer A senior team of 9+ means we ship faster than a solo Full Stack Developer or AI Engineer and survive bus factor. CEO and Co-Founder oversight on every project means architecture decisions get made by someone with 14+ years of shipped products behind them — not by whoever happens to be assigned to your account. And because we work as a single agency rather than a marketplace of strangers, the engineer reviewing your code on Friday is the same one fixing the bug on Monday. If you’re building a B2B SaaS or Fintech platform and need a senior team that ships, let’s talk.
