I build AI agents and RAG systems that give trustworthy answers, not plausible-sounding guesses. 9+ years full-stack, Top Rated Plus, 100% Job Success Score. What I actually solve: Most "AI features" fail the same way: the model sounds confident and is wrong. I build the layer that prevents that, grounding every answer in real data, validating before it reaches the user, and making failures visible instead of silent. That's the difference between a demo and something a business actually trusts. Core expertise: 🔹 AI Agents & RAG — natural language to structured, grounded output. Built Vanna AI, an agent that converts questions into SQL, executes it, and validates results before answering. 🔹 Claude Code, daily driver, not occasional use. I make codebases agent-ready (CLAUDE.md, module context, safe patterns), then use adversarial AI review, a second model challenges the first's output before a human ever sees it. I've built MCP servers exposing clean tool calls on top of production backends. 🔹 Full-stack: Python (Django, FastAPI), Node.js, React, Next.js, TypeScript. Databases: PostgreSQL, MySQL, MongoDB, Redis, vector stores (pgvector, Pinecone). 🔹 Document & data intelligence: built Befiler, an AI platform extracting and validating structured data from financial documents, and Fidap, ETL pipelines with AI-assisted data cleaning. 🔹 DevOps & security: Kubernetes, Docker, CI/CD (GitHub Actions, GitLab), GitOps (FluxCD/ArgoCD), RBAC, least-privilege access, secrets management, audit logging. Real projects, not just claims: Vanna AI (vannaai), Befiler, Fidap, LinkGraph/SearchAtlas, Ablestar (Shopify product-ops platform, ablestar). How I work: PRD, plan, AI-assisted build, adversarial review, human review, staging, production, monitoring. AI never ships to production unsupervised, speed doesn't replace judgment. I read your job post before I write a proposal, if I message you, it's because I can genuinely help, not because I mass-applied. Let's talk about what you're building.

Full-Stack Engineer who builds scalable web apps that hold up in production — Angular & React on the front, Java Spring Boot & Python (Django/Flask) on the back. 100+ projects delivered, 0 missed deadlines. WHAT I BUILD → Enterprise-grade REST APIs and microservices with Java Spring Boot → Dynamic, responsive front-ends with Angular and React → Lightweight Python backends with Django and Flask → Automated web scrapers that extract, clean, and deliver structured data at scale → Database design & optimization — PostgreSQL, MySQL, MongoDB TECH STACK Frontend: Angular | React | JavaScript (ES6+) | HTML5 | CSS3 Backend: Java Spring Boot | Python Django | Flask Databases: PostgreSQL | MySQL | MongoDB Scraping: BeautifulSoup | Selenium | Scrapy | Playwright Tools: Git | REST APIs | Docker | Postman HOW I WORK I don't just write code — I ask what the feature is actually for before touching a keyboard. That means fewer revisions, cleaner architecture, and software that solves the real problem, not just the surface one. You get: ✔ Clean, documented, maintainable code ✔ Regular updates — you'll never be left wondering where things stand ✔ Honest timelines — I'd rather under promise and overdeliver ✔ A developer who thinks about your business, not just the ticket GOOD FIT FOR - SaaS platforms and internal tools - REST API development and third-party integrations - Data scraping pipelines and automation - Full-stack builds from MVP to production - Migrating or refactoring legacy systems If you're building something and need a developer who gets it done cleanly — send me the brief.

I am an AI/ML Specialist who lives by the motto "Stop chasing the hype. Build something users trust." I build AI-powered chatbots, platforms, automation systems, and real-time applications that combine strong backend engineering with practical AI implementation solutions that actually survive production traffic, unpredictable users, API failures, scaling pressure, and long-context conversations, not just “wrapper around GPT” products. My work typically involves architecting and scaling systems powered by OpenAI, Claude, LangChain, RAG pipelines, vector databases, real-time communication infrastructure, and custom backend services. I have worked across IoT, BLE, Healthcare, Education, AI Chatbot platforms, Fitness, Ride-hailing, Food Delivery, FinTech, Dating, Matrimonial, eCommerce, Gaming, and other high-scale, engagement-heavy systems. In terms of collaboration, expect: No ghosting. No guesswork. Just proactive, hyper-structured updates, technical clarity, transparent timelines, and deep collaboration from architecture reviews to sprint execution. That said, drop your product idea, biggest bottleneck, or enhancements you are seeking/ failures in the existing system in my inbox, and I’ll send back a practical, execution-focused technical roadmap designed to move your project/platform forward in the most efficient and scalable way possible.

Production AI systems are what I build: RAG, agentic workflows, and real-time voice with sub-500ms latency. .NET and Python stacks. 15+ years shipping for production, including Intersight AI (RAG document intelligence on Azure OpenAI) and InTake AI (real-time voice agent on .NET Core + SignalR). Most "AI projects" stall at the gap between a working prototype and a system that holds up under real traffic, real edge cases, and real auditability. That gap is what I close. WHAT I ACTUALLY BUILD RAG systems with hybrid search, structured extraction, and confidence scoring (not just chunk-and-stuff) Agentic workflows where determinism, error recovery, and human-in-the-loop are designed in from day one Real-time voice AI with measured latency budgets across STT, LLM, and TTS Multi-tenant SaaS platforms with proper tenancy isolation, background jobs, and observability Production-grade .NET Core and Python (FastAPI) backends with full CI/CD, monitoring, and rollback paths WHERE I'VE SHIPPED EmpowerNow: an enterprise AI orchestration platform using Python FastAPI microservices. Developed Agentic RAG pipelines with support for Pinecone, Weaviate, Milvus, Qdrant, and Chroma. Intersight AI: Production RAG on Azure OpenAI with LangGraph, structured document extraction, clause-level scoring InTake AI: Real-time voice AI, sub-500ms end-to-end latency, .NET Core + SignalR streaming STT/TTS SkyBoss: Multi-tenant field-service SaaS serving hundreds of companies, Stripe billing, cross-account reporting Eureeca: Global equity crowdfunding platform, KYC/AML compliance SMP Pharmacy: HIPAA-compliant mobile app with EMR integration, RBAC, and audit trails THE STACK I REACH FOR LLM and AI: OpenAI, Azure OpenAI, LangGraph, LangChain, vector databases (Pinecone, ChromaDB, pgvector), structured outputs, evaluation harnesses Backend: Python (FastAPI), microservices, REST and GraphQL APIs, Redis, .NET Core, C#, PostgreSQL, SQL Server Frontend: Angular, React, Next.js, TypeScript Cloud: Azure (Functions, Container Apps, AI Search, App Service), AWS, Docker, Kubernetes basics, CI/CD pipelines HOW I WORK Each milestone ships with a Loom walkthrough and a shared staging environment you can poke at. Weekly written summary covering what shipped, what's blocked, what's next, so you're not chasing for status. I scope before I quote, push back when something won't scale, and write tests on day one rather than as cleanup. GMT+5, response within 2-3 hours during your working day. WHO THIS IS FOR Founders are moving an AI prototype to production. Teams modernizing legacy .NET or SaaS platforms. Companies that need a senior engineer who can own architecture decisions and ship, not just take tickets. If you're building chatbot wrappers or one-off scripts, I'm not the right fit. Happy to jump on a 30-minute Zoom to walk through your architecture and where I'd start.
