15+ Years of Engineering Excellence. Transforming Complex Data Chaos into Scalable Enterprise AI Solutions. You hired developers to integrate AI, but you can’t tell if they are building the right workflows — or building them right. Your technical infrastructure is burning cash, data is leaking between your systems, and you are spending half your week making architectural decisions you shouldn't be making alone. If I were architecting your system, I would focus on creating a modular, cloud-native blueprint where data flows seamlessly, AI components reason with deterministic accuracy, and your operational costs drop by design. I am a fractional CTO, AI Architect, and Lead Data Engineer with a Ph.D. in Mathematics. I embed with your business to provide senior technical leadership without the full-time corporate overhead. I bridge the gap between heavy enterprise data warehousing (DWH), microservices, and frontier generative AI. 𝐇𝐨𝐰 𝐈 𝐖𝐨𝐫𝐤 I don't just jump on a brief weekly advisory call to give generic feedback. I take absolute ownership of the technology side of your business: Architecture & Guardrails: I make core architecture decisions, design resilient multi-agent systems, and prevent critical data formatting leaks. Quality Oversight: I manage developers, enforce high coding standards, perform strict code reviews, and keep delivery on track. Lightweight Agile: I introduce short sprints and daily check-ins so that an underperforming agency or developer is caught in week two, not month three. Core Technical Stack & Keywords AI & Generative Models: LangGraph, LangChain, AutoGen, OpenAI (GPT-4o), DeepSeek, Llama, Gemini, Vertex AI, RAG Pipelines, Multi-Agent Orchestration. Data Engineering & DWH: Data Modeling, Data Warehousing, Data Lakes, Self-Healing ETL Pipelines, Anomaly Detection. Databases & Infrastructure: PostgreSQL (+ pgvector), Oracle/Exadata, MS SQL, Google BigQuery, Snowflake, AWS Redshift, Docker, Kubernetes, GitLab CI/CD. Backend & Scripting: Python, Node.js, PL/SQL, SQL, Java, Golang. Selected Track Record & Milestones AI-Powered Multi-Agent Platforms (Travel & EdTech): Designed and built automated multi-agent AI frameworks from scratch featuring real-time conversational streaming voice interfaces and semantic vector searches (RAG) for unmatched response accuracy. Enterprise FinTech Infrastructure Modernization (VP of Engineering): Refactored 12+ core legacy trading services into high-load, cloud-native microservices with NATS eventing, eliminating system friction across global time zones. Scalable DWH & Global Data Engineering (CTO / Tech Lead): Directed 20+ full-cycle data engineering projects. Engineered automated, self-healing ETL pipelines and reduced enterprise ETL maintenance costs by 40%. 𝐖𝐡𝐚𝐭 𝐈 𝐃𝐨𝐧'𝐭 𝐃𝐨 I am not writing boilerplate code 40 hours a week. I review architecture, unblock your engineering team, and handle high-level logic. I am the architect, not the construction crew. I do not make product/business decisions. You decide what to build to hit your market target. I decide how to build it so it scales reliably and doesn't crash under high-load transactions. I am not an agency. I have no affiliation with outsourced development shops. When I recommend a tool, a framework, or a talent hire, it is 100% unbiased. 𝐅𝐀𝐐𝐬 𝐐: Can you participate in investor or due diligence calls? 𝐀: Absolutely. I have extensive experience translating complex financial, auditing, and technical data into clear language that investors, stakeholders, and compliance officers understand. You can put me on your pitch materials or website as your technical advisor. 𝐐: What if my current team or outsourced agency is underperforming? 𝐀: Once I introduce structured sprints, code observability tools, and automated pipelines, it becomes impossible to hide behind vague deadlines. I coach internal talent first — and if that doesn't work, I help you make the transition. 𝐐: What tech stack do you work with? 𝐀: I am stack-agnostic, but I specialize heavily in Python, Node.js, PostgreSQL, AWS, and modern generative ИИ frameworks. I choose technology that fits your current business stage and operational budget, not just what's trendy. Let's Build Something Scalable If your business matches this situation, send me a message. Tell me what you are building, what is going wrong, and what you’ve tried so far. I will tell you honestly whether I can help you fix it. Let’s connect for a brief discovery session to align your system architecture with your business goals.
