Are you looking to build a high-performance SaaS platform, automate a complex supply chain, or integrate secure, production-ready AI into your business workflow? Many developers can write code, but very few understand how to seamlessly blend cutting-edge AI/ML systems with scalable, enterprise-grade architecture while ensuring strict data security (HIPAA, PCI-DSS). I am a Full-Stack Developer and AI/ML Engineer with extensive experience architecting end-to-end solutions for SaaS, Supply Chain, Healthcare (HIS/HMS), and custom ERP systems. Whether you need to build an MVP from scratch or scale an existing enterprise platform, I deliver clean, maintainable code and robust infrastructure. 🚀 Core Expertise & How I Can Help You: AI/ML & GenAI Integration: Building intelligent RAG systems, custom chatbots, and LLM-powered workflows using OpenAI, Anthropic, LangChain, and Vector Databases (Pinecone, Qdrant). Robust Backend & Architecture: Designing secure, high-throughput microservices and APIs using Node.js (NestJS), Python (FastAPI/Django), and PHP, backed by PostgreSQL, MongoDB, or Redis. Modern, Responsive Frontends: Crafting seamless web and mobile interfaces using React, Next.js, Angular, Vue.js, and React Native. Cloud, DevOps & Compliance: Deploying production-ready applications on AWS/GCP/Docker with CI/CD pipelines, keeping security and regulatory standards (HIPAA, GDPR) at the forefront. 🛠️ Technical Snapshot: Frontend: React, Next.js, Angular, Vue.js, React Native, Tailwind CSS Backend: Node.js (NestJS/Express), Python (FastAPI/Django), PHP, Java AI/ML: LLMs, LangChain, Vector DBs, Prompt Engineering, RAG Systems Cloud & Databases: AWS, GCP, Docker, Kubernetes, PostgreSQL, MySQL, MongoDB, Redis Let’s build something scalable.

I build automation systems and reporting pipelines that cut manual work and make operations actually scale. Over the past 5+ years I've worked across analytics, operations, and AI automation at companies like Beam Mobility, 500 Global, and Kaya — and more recently as an independent consultant delivering end-to-end automation projects for clients in insurance and manufacturing. Recent project examples: — Built a UAT automation pipeline for an insurance company's SME web portal (Python, Playwright, Gemini AI, n8n, GitHub Actions) — reduced manual test cycles significantly — Designed an AI-assisted supply chain workflow for a manufacturing client covering forecast planning and ops reporting — Built a Metabase dashboard automation system in Python for a fintech startup — Led data operations and reporting at Beam Mobility and portfolio analytics at 500 Global What I'm good at: — Translating messy, multi-source data into clean dashboards decision-makers can use — Building automation pipelines that actually run reliably (not just POCs) — Working across SQL, Python, n8n, BigQuery, Looker Studio, HubSpot, and AI tooling (Claude, Gemini) — Documenting clearly so nothing breaks when I'm not around I work best on projects with defined scope and real deliverables — not vague strategy engagements. If you need something built properly and documented well, let's talk.

I help enterprises, founders & funded startups building scalable production grade MVPs, multi-tenant SaaS platforms, AI SaaS, web, mobile, desktop & software applications, internal tools, business process automation systems, data-intensive backend systems & cloud-native platforms designed for scalability, reliability, security, maintainability, observability, and long-term growth. I’m 𝐓𝐨𝐩 𝟏% Senior Full Stack AI & Software Developer (expert vetted by Upwork) with 18 years of ‘traceable experience’ architecting, developing & deploying custom production-grade software platforms, including custom AI-powered SaaS apps I serve as a strategic ‘technology partner’ throughout the SDLC: from product requirements mapping, system architecture design, database design, API strategy, AI integration, and infrastructure planning to front-end & back-end development, full-stack development, cloud deployment, production launch, and ongoing support. I’ve delivered 200+ custom software solutions for Fortune 500 companies, US enterprises, founders, and funded startups across 38 countries, with a strong track record of client satisfaction. My work usually starts with building an MVP from scratch, scaling a product with traction, modernizing a legacy system, rescuing an unstable platform, improving performance, or integrating AI/new product capabilities without disrupting core operations. From there, I convert business goals, ROI expectations, user workflows, compliance needs, budget, and timeline into a development plan covering scope, milestones, architecture, integrations, testing/UAT, and rollout. For founders and funded startups, I help turn early product ideas, business models, and ROI expectations into a focused MVP scope, scalable architecture, launch roadmap, and growth plan without overbuilding too early. I design system, cloud, data, AI, SaaS, security, and integration architectures based on product stage, scalability needs, compliance requirements, operational complexity, and cost. My approach covers practical architecture decisions, secure integrations, tenant isolation, data modeling, AI-ready data foundations, production deployment, observability, reliability planning, and long-term maintainability.
