AI Engineer & Full-Stack Architect | 20+ Years Experience | LLMs, AWS

20+ years of professional experience | 12 years on Upwork | 100% 5-star client feedback | Master of Computer Science | AWS AI Certified In 20+ years of engineering, I’ve learned that a successful product isn't just about code—it’s about technical ownership. Whether you are a founder launching a new AI-driven venture or an enterprise scaling to millions of users, I provide the strategic leadership and full-stack execution required to turn a vision into a robust, secure, and scalable reality. Why work with me? Fractional CTO Leadership: I act as your technical partner, managing agile sprints, defining best practices, and ensuring your roadmap is realistic and cost-effective. Master’s Level Architecture: With a Master’s in CS, I don't just "build apps"—I design systems. From handling high-concurrency Facebook apps (1M+ users) to solving complex mathematical constraint problems (SBC Solvers), I ensure your architecture is built for the long term. AI & LLM Specialization: As an AWS AI Certified architect, I specialize in the 2025 tech stack: RAG pipelines, agentic workflows, and secure AI integrations (using Python, FastAPI, and LangChain). Core Pillars of Expertise 1. AI Development & Data Strategy I design and deploy intelligent systems using modern LLM frameworks. I focus on accuracy, cost-efficiency, and data privacy (PII/PHI redaction). Tools: RAG, Weaviate, LangChain, Supabase, n8n, OpenAI/Anthropic API. 2. Full-Stack Web & Mobile Mastery I build high-performance, cross-platform experiences. Whether it’s a web-based enterprise dashboard or a high-engagement mobile app, I ensure SEO optimization and maintainable code. Stack: Python (Django/FastAPI), Node.js, React, React Native (Expo), Angular, PHP (Laravel). 3. Infrastructure & Cloud Governance I move projects from "messy prototypes" to "enterprise-grade" production environments with high security and 99.9% uptime. Cloud: AWS (Lambda, RDS, S3), Docker, CI/CD, Firebase, PostgreSQL/MySQL. Technical Evolution (2000 – 2025) Modern (2023-Present): Generative AI, Python/FastAPI, RAG Architecture, Vector DBs, Agentic Workflows. Mobile & Frontend: React Native, Expo, React, Next.js, Angular 2+. Backend & Logic: Node.js (Express/NestJS), Laravel, PHP, Python(Django/FastAPI), Supabase, Firebase Data & Systems: PostgreSQL/TimescaleDB, MongoDB, Weaviate, MySQL, Oracle, AWS, Docker, Git. The "Five-Star" Guarantee: I have been on Upwork for 12 years with 100% positive feedback. This is because I prioritize transparency, strict documentation, and clear communication. I am available for up to 40 hours per week to take full ownership of your technical success. Ready to build? Let’s schedule a consultation to discuss your architecture.
