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.
Iโm ๐๐จ๐ฉ ๐% Senior Full Stack AI & Software Developer (expert vetted by Upwork) with 18 years of โtraceable experienceโ architecting, developing & deploying custom production-grade software platforms, including custom AI-powered SaaS apps
I serve as a strategic โtechnology partnerโ 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.
Iโve 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.
Industry & domain experience: I've built & modernized software architecture across Healthcare, EHR, EMR, HIPAA, FinTech, Finance, Banking, Insurance, Sales & Marketing, Education, Legal, Manufacturing, Chemical, Media, Real-estate, Supply-chain, Logistics, Construction, Automotive, Retail, AI SaaS MVP, B2B SaaS, eCommerce, iGaming, Marketplaces,delivery, booking, listing, mobile apps, EdTech, LMS, CRM, ERP, Business process automation, multi-tenant SaaS Platforms
