I am a senior financial and systems architect with a rare, 15-year career built at the intersection of institutional finance and full-stack development. I don't just analyze business problems; I architect and build the robust, end-to-end software solutions that solve them permanently. My expertise is in designing and building the "AI core" and data infrastructure for high-stakes financial and operational systems. I specialize in projects that require a deep, first-principles understanding of the business logic (from M&A valuation to derivative modeling) and the hands-on engineering skill to build the production-grade applications that bring that logic to life. Whether you need a complex financial model, a multi-API data pipeline, or a complete, AI-driven web application, I deliver institutional-grade solutions that are scalable, auditable, and built for real-world decision-making. Core Competencies (What I Deliver): Full-Stack Application Development: Architecting and building complete, end-to-end internal tools and data applications. This includes: Backend & API Architecture: Designing and building robust backend services, multi-REST API integrations, and LLM orchestration engines using Python (FastAPI, Django) and SQL/NoSQL databases. Frontend & UI/UX: Creating clean, intuitive, and interactive web-based applications and dashboards using Streamlit and other modern frameworks to allow non-technical users to execute complex scripts and analysis. Quantitative Finance & Modeling: Building institutional-grade financial models from the ground up, including M&A valuation, project finance, derivatives, and sophisticated stochastic models (Monte Carlo simulations) for risk analysis. AI & Machine Learning Engineering: Designing and implementing production-ready AI pipelines, from custom ML models for predictive forecasting to RAG (Retrieval-Augmented Generation) systems for intelligent document analysis and automated reporting. Financial Systems & Data Architecture: Architecting and managing the data pipelines, consolidation logic, and reporting frameworks for complex, multi-entity global organizations (140+ entities, 51 countries). Technical Skillset (The "How"): Languages & Frameworks: Python (Expert), SQL (Expert), C++, Java (Spring Boot), JavaScript Backend & APIs: FastAPI, Django, REST API Design & Orchestration, LLM Integration (OpenAI) Frontend & BI: Streamlit, React.js (Proficient), Power BI, Looker Studio Databases: PostgreSQL, DuckDB, MongoDB, SQLite Data Science & ML: Pandas, NumPy, Scikit-learn, PyTorch, LangChain, LlamaIndex Legacy & Enterprise: Advanced Excel, VBA, SAP BFC, HFM I thrive on architecting solutions to complex, data-intensive challenges. My unique value is my ability to operate as a true hybrid: a senior finance professional who can think at a strategic level and a full-stack engineer who can build the production-grade tools to execute that strategy. Let's build something robust, intelligent, and valuable together.

Hey, I’m Damian. I build AI automations that save B2B teams 20+ hours a week and run 24/7 without breaking. 300+ deployed, zero drama. Shoot me a message or invitation and I'll send back a personalized Loom breaking down how I'd approach your specific project. No templates, no copy-paste proposals. ============================ HERE'S MY DEAL Before I got into AI automation, I spent years in military cybersecurity building machine learning systems to detect zero-day attacks and managing data pipelines across classified networks. I have a Master's in Applied Data Science from the University of Michigan and 7 GIAC security certifications. Now I take that same engineering discipline and apply it to AI automation for businesses. The systems I build don't just work in a demo. They survive production because I come from an environment where failure wasn't an option. Whether your team is buried in spreadsheets, manually moving data between platforms, or running the same process fifty times a day, I'll design a system that takes it off your plate permanently. 300+ n8n automations deployed 100% Job Success Score | Top Rated Plus Master's in Applied Data Science (University of Michigan) 7x GIAC Certified (Machine Learning, Python, Cybersecurity) I use Claude API every single day - it's my primary tool, not something I learned yesterday Everything gets built on your accounts, your infrastructure. You own it all, zero lock-in ============================ WHAT I DELIVER AI Agents That Actually Reason I build multi-agent systems with Claude API and MCP that handle complex logic - not just simple if/then chains. Running costs as low as $0.02 per execution. Bulletproof n8n Workflows Production-grade automation with proper error handling, logging, and alerts. The kind that runs reliably at 3am without you worrying about it. Full-Stack AI Applications Complete apps with Next.js, React, Supabase - authentication, billing, AI features baked in. Deployed and ready to scale. Lead Gen & Content Pipelines Automated content creation and lead processing at scale. I've processed 880 leads for under $2 and generated 2,073 qualified leads in a single day. CRM & API Integrations Salesforce, HubSpot, GoHighLevel, Pipedrive, Zoho - properly connected and automated, not just surface-level syncs. ============================ WHAT CLIENTS SAY "Wish I had met more freelancers with this high-quality work ethic and delivery - 100% recommended. Great communication, fast delivery, hard working, listening, and looking for feedback. Can't recommend enough." - Elon S. "Damian was awesome! He'd clearly done his research before hopping onto our intro call, and worked steadily and quickly on a project that was admittedly pretty complex. He kept scalability in mind, was friendly and thoughtful, and altogether a pleasure to work with." - Maria Ada S. ============================ WHAT SETS ME APART Military-grade engineering background. I built ML systems that detected cyberattacks before they happened. That same rigor goes into every automation I build for you. I work across both code and no-code. Python, TypeScript, n8n, Make - I choose the right tool for the job, not the one I'm most comfortable with. Claude isn't a buzzword on my profile. I ship production systems with it daily. Before anything gets built, you get a clear scope and cost breakdown. No surprises. I communicate like a human, respond within 6 hours, and actually care about whether the thing I built is working for you after handoff. ============================ Upwork Skill Certification - Python Development Back-End Development GIAC Machine Learning Engineer (GMLE) GIAC Python Coder (GPYC) GIAC Certified Forensic Analyst (GCFA) GIAC Certified Intrusion Analyst (GCIA) Global Industrial Cyber Security Professional (GICSP) ============================ LET'S GET STARTED If you've got a process that's eating up your team's time, message me.
