And in every case I have noticed: 𝐭𝐡𝐞 𝐬𝐮𝐫𝐫𝐨𝐮𝐧𝐝𝐢𝐧𝐠 𝐬𝐲𝐬𝐭𝐞𝐦 𝐰𝐚𝐬𝐧'𝐭 𝐝𝐞𝐬𝐢𝐠𝐧𝐞𝐝 𝐩𝐫𝐨𝐩𝐞𝐫𝐥𝐲. And worst of all, in some cases an AI agent wasn't connected to the right workflows, data, validation layers, and business rules. And user experience too were rarely creating meaningful business value. 𝐀𝐍𝐃 𝐓𝐇𝐀𝐓'𝐒 𝐖𝐇𝐄𝐑𝐄 𝐈 𝐇𝐄𝐋𝐏: I (and sometimes my team) work with founders, startups, and growing businesses to design and build AI systems that operate inside real-world environments. Systems we built help teams automate workflows, retrieve knowledge, support decisions, qualify leads, process data, and scale operations. 𝐋𝐄𝐓'𝐒 𝐋𝐎𝐎𝐊 𝐀𝐓 𝐑𝐄𝐂𝐄𝐍𝐓 𝐖𝐎𝐑𝐊: ✔ Enterprise AI Retrieval Platform combining RAG, NL2SQL, schema linking, validation layers, and intelligent query generation ✔ AI-Powered Career Intelligence Platform used to generate personalized resumes, career recommendations, and job application content ✔ Compliance-Aware AI Email Agent for automated outreach, qualification, and response management ✔ AI Voice Agent systems for lead engagement, qualification, and workflow automation ✔ Computer Vision solutions using YOLO, GPT Vision, and custom AI pipelines ✔ AI-powered automation ecosystems integrating OpenAI, Claude, CRMs, Slack, databases, APIs, and business workflows ✔ AI-powered mobile and web applications used by real customers 𝐂𝐋𝐈𝐄𝐍𝐓𝐒 𝐓𝐘𝐏𝐈𝐂𝐀𝐋𝐋𝐘 𝐂𝐎𝐌𝐄 𝐓𝐎 𝐌𝐄 𝐖𝐇𝐄𝐍: • They want to build an AI product from scratch • They have an AI prototype that now needs production architecture • They want AI integrated into an existing application • They need RAG, AI agents, automation, or knowledge systems connected to business workflows • They want technical guidance before making significant development investments 𝐌𝐘 𝐀𝐑𝐄𝐀𝐒 𝐎𝐅 𝐄𝐗𝐏𝐄𝐑𝐓𝐈𝐒𝐄: • AI Agent Development • Workflow Automation using n8n, Make, and Zapier • Retrieval-Augmented Generation (RAG) • OpenAI & Claude Integrations • Voice AI Systems • Computer Vision • AI-Powered SaaS Products • Mobile & Web Applications • Product Architecture & System Design • API Integrations • Multi-Agent Systems • Cloud Infrastructure What clients often appreciate most is that I start with the business objective than technology. Then I work backwards to determine whether the right solution is an AI agent, RAG platform, workflow automation, computer vision system, AI-powered application, or a combination of multiple systems working together. So, if you're exploring an AI product, internal copilot, AI agent, automation platform, RAG solution, computer vision application, or AI-powered SaaS product, feel free to reach out. I'm happy to discuss the idea, challenge assumptions where needed, and help identify the most practical path to building it successfully.

SYSTEM DESIGN MEETS FULL STACK DEVELOPMENT System design and full stack development are usually two different people two different conversations and two different bills. I bring them into one. Every system I design is grounded in how it will actually be developed and every application I build starts with a foundation that was properly thought through before anyone opened a code editor. DOCUMENTATION AND SYSTEM DESIGN - Write full Software Requirements Specifications to the IEEE standard detailed structured and actually usable by developers not the kind that gets ignored - Build complete UML diagram sets including Use Case Class Sequence Activity and State Machine diagrams - Create Data Flow Diagrams Entity Relationship Diagrams Component Deployment and Swimlane diagrams - Write User Stories and Functional Descriptions that translate business needs into clear technical requirements - Work in Drawio Lucidchart and Visual Paradigm and hand off documentation FULL STACK DEVELOPMENT - Frontend React TypeScript Vite and Tailwind CSS - Backend Nodejs Expressjs and RESTful API design - Databases PostgreSQL MySQL MongoDB and Prisma ORM - Caching Redis for session management and performance - Authentication JWT and Role Based Access Control - Deployment AWS EC2 Docker and Nginx WHY CLIENTS KEEP COMING BACK - Most developers skip planning and most technical writers cannot actually build software I do both - When I design I think about how it will be built not just how it looks on paper - When I build I bring the same discipline and structure that goes into good system design - Worked with clients across the US UK and Canada with a consistent five star track record If your project needs a solid foundation before development begins I would love to help you get it right from day one

I write the specs that stop your dev team from guessing. Most software delays trace back to one root cause: requirements that felt clear in a meeting but fell apart in development. I close that gap turning fuzzy product ideas into structured PRDs, SRDs, and entity models that developers can build from without back-and-forth. 15+ years across SaaS, marketplaces, ERP systems, and AI-enabled platforms. $300K+ earned on Upwork, 100% Job Success, 125 completed contracts. Recent work includes: MVP scope and requirements for a recruitment-matching SaaS platform Multi-ERP data unification strategy for an automotive group (EMBA capstone, Bocconi) AI governance specification work for a constitutional AI platform BA for a legacy software re-engineering project (298 hrs, ongoing client) Where I add the most value: Translating ambiguous product ideas into structured PRDs/SRDs/FRDs Designing entity models and data flows for complex or multi-system platforms Structuring PIM/data-matching/unification processes for marketplaces and ERP environments Scoping AI features into existing products without overengineering Acting as the translation layer between non-technical stakeholders and dev teams Certified Scrum Product Owner. Currently completing an EMBA in Digital Transformation (SDA Bocconi). Why not just use AI to generate this myself? AI tools are excellent at producing a document — they're not good at knowing what questions to ask, what's missing, or what will actually break in production. I use AI extensively in my own workflow to draft faster and model edge cases, but the requirements-gathering, stakeholder alignment, and judgment calls that prevent costly rework still require a human who's done this 125 times. Think of me as AI-augmented, not AI-replaced.

I’ve been writing code long enough to remember when BASIC felt like magic and when a “debugger” was mostly your own frustration. Across four decades, tech has changed faster than hairstyles, but I’ve happily kept both up to date. My coding journey, decade by decade: - 1980s: BASIC (my first love ❤️) and a bit of C - when computers were loud, slow, and beautiful - 1990s: Pascal, Cobol, C++ - the era of serious programming and questionable UI design - 2000s: PHP + MySQL - building the early web one spaghetti script at a time - 2010s: Java and JavaScript - enterprise on one side, wild west on the other - 2020s: Node.js, React, Solidity, Python — AI, blockchain, automations, and everything in between Along the way, I realized I don’t just like building software, I like building teams, systems, and processes that actually work. So I spent the last years mixing: - Project & Product Management across IT and SaaS - International Development projects (where "deadline flexibility" is a lifestyle) - Banking & fintech (where deadlines stop being flexible) - Academia, mentoring, research and development And yes… the real mining industry - not crypto mining, actual mining with rocks, helmets, and very serious engineers... Today I’m a hybrid: 🔧 Engineer by instinct 📊 Product/Project Lead by experience 🌍 International collaborator by habit 🤖 Automation & AI enthusiast by passion If it involves solving problems, building something new, or turning chaos into a process - I’m probably interested.
