I help regulated organizations design secure AI, RAG, and data systems that are practical to implement and defensible in review. My work connects the parts that determine whether an AI initiative can move beyond a promising demo: data classification, identity and access, retrieval quality, logging, integration security, and clear operating guardrails. I turn those constraints into an architecture and implementation roadmap that technical and non-technical stakeholders can use. I bring 25+ years across enterprise architecture, data systems, cloud, and security. I currently support a state agency, where my work includes security architecture and governance for AI, data, and integration platforms in a public-sector environment. Typical engagements include: • Secure AI and RAG architecture reviews • AI governance and readiness assessments • Production-readiness and security reviews for web platforms • Identity, zero-trust, API, and integration security • Document intelligence and enterprise search design I also bring deep specialist experience in email deliverability, DNS, sender authentication, and transactional-email infrastructure—particularly useful when email is part of a launch-critical customer journey. If you need a clear, low-risk path from complex technical constraints to an executable plan, I can help.

Businesses often need more than just a developer. They need someone who can understand the requirement properly, suggest the right approach, and build a product that works smoothly in real use. I help startups, founders, and growing businesses build web applications, mobile apps, SaaS products, MVPs, and custom business platforms with a strong focus on clarity, performance, and long term scalability. With 15+ years of experience in software development, I have worked on projects from idea stage to launch, and also on existing platforms that needed improvements, feature expansion, workflow refinement, or complete redevelopment. My work covers both frontend and backend, so clients do not need to manage multiple developers for one product. I focus on understanding the business goal first, then translating it into a practical and reliable solution. This helps reduce confusion during development and keeps the project aligned with the real requirement. **What I can help with:** ---------------------------- • Custom web application development • Mobile app development (Hybrid and Native) • SaaS product development • MVP development • Admin panels and dashboards • API development and third party integrations • Ecommerce and marketplace platforms • Maintenance and feature enhancement of existing products **Tech stack I work with includes:** React, Node.js, Laravel, Flutter, Python, WordPress, Shopify, Swift, Kotlin, and API based integrations. Clients usually appreciate working with me because I bring clear communication, structured execution, dependable support, and a practical approach to solving product challenges. Whether you need to build a product from scratch, improve an existing application, or develop a stable MVP with the right technical foundation, I can help move the project forward in a clear and efficient way. If you are looking for a developer who can combine technical execution with a strong understanding of business needs, I would be glad to discuss the scope and suggest the right approach.

I’m a brand and UX/UI designer with 10+ years of experience working with tech companies of various sizes and stages, from high profile venture-backed startups backed by venture capital firms like Sequoia, a16z, and Y Combinator to large tech companies. I’ve collaborated with companies across many different sectors from SaaS, to AI, to healthtech, real estate tech, fintech, and more. I pride myself on delivering design solutions that combine aesthetics with functionality. If you have a project you’d like to collaborate on, I’d love to hear from you.
