You will get a Fractional CTO Strategy & Scalable Enterprise Architecture
Top Rated
Project details
Most startups fail not because of a bad idea, but because of a brittle foundation. As a Fractional CTO and Enterprise Architect with over 12 years of experience—trusted by global leaders like HSBC, Mastercard, and Deloitte—I bridge the gap between "Research AI" and "ROI-Driven Enterprise AI".
What sets this project apart is the Coretus Advantage. I implement proprietary, battle-tested, SOC2-ready modules for Authentication, Security, and Payments at zero cost. This ensures your budget goes 100% toward business logic and custom AI features rather than basic infrastructure.
Whether you are migrating a legacy monolith to Microservices or launching an AI-powered MVP, I provide the strategic oversight and high-level architecture required to scale to millions of users. You maintain 100% Code & IP Ownership while I ensure your system is architected for success from Day 1. Let’s build a secure, debt-free, and Series A-ready foundation for your venture.

Expert AI Tech Team & Fractional CTO for Enterprise Software
Coretus gave us confidence from the very beginning with their CTO-led approach and clear understanding of our vision. Instead of feeling like we were managing multiple resources, we felt like we had a dedicated technology partner. Their focus on scalability, security, and speed to market aligned well with what we were looking for. Overall, the team brought clarity, ownership, and a level of professionalism that made the process much smoother.

Hire Fractional CTO for Enterprise AI Roadmap & SaaS Architecture
We worked with Coretus to develop a complete e-commerce website for our jewellery business, and the experience has been excellent. Their team demonstrated strong technical expertise, great speed in execution, and a very proactive approach throughout the project.
One thing that truly stood out was their flexibility. During the project, we had to make a few sudden changes to the requirements, and the team handled everything smoothly without hesitation. They quickly resolved the challenges and ensured the project stayed on track.
We were genuinely impressed by the professionalism, adaptability, and technical knowledge of their developers. It was a pleasure working with such a reliable team.

Job Success
Rajkot, India - 6:47 pm local time
I’m a Fractional CTO, AI Engineer, and Full-Stack Developer with 14+ years of experience, Top Rated on Upwork with 100% Job Success and $100K+ earned. My experience includes work with Deloitte, HSBC, Mastercard, PepsiCo, and Airbnb.
Clients usually bring me in when the challenge is bigger than “just write the code” — when AI, product architecture, APIs, private data, security, and scale all need to work together.
That’s where I add the most value.
◆ FRACTIONAL CTO & SOLUTION ARCHITECTURE
I work with founders, CTOs, and engineering teams on product architecture, technical strategy, system design, technology selection, technical roadmaps, engineering processes, technical debt, and scaling decisions.
I can help you validate an architecture before development starts, improve an existing product, guide an engineering team, or step in when technical complexity is slowing the business down.
I’m not interested in adding complexity for the sake of architecture. The goal is to make the right decisions for the product you have today while keeping tomorrow’s growth in mind.
◆ AI AGENTS, RAG & GENERATIVE AI
I design and build production-grade AI Agents, Agentic AI systems, RAG applications, LLM solutions, and AI automation.
My work includes Multi-Agent Systems, AI Copilots, LangGraph, CrewAI, MCP, tool calling, structured outputs, human-in-the-loop workflows, semantic search, hybrid search, re-ranking, document intelligence, and vector databases.
I work with OpenAI's GPT, Anthropic's Claude, Google's Gemini, Llama, Pinecone, Qdrant, Weaviate, and pgvector.
What matters to me is what happens after the demo — retrieval quality, hallucination reduction, security, evaluation, observability, latency, and cost.
I also won’t force AI into a problem that doesn’t need it. If deterministic software, APIs, or conventional automation are the better solution, that’s what I’ll recommend.
◆ FULL-STACK & SAAS DEVELOPMENT
I can own the complete product, not only the AI layer.
My core stack includes Python, FastAPI, Node.js, TypeScript, React, Next.js, PostgreSQL, Redis, REST APIs, GraphQL, and Microservices.
I build AI SaaS, B2B SaaS, multi-tenant platforms, enterprise applications, admin systems, and workflow products with authentication, RBAC, subscriptions, billing, analytics, and third-party integrations.
Whether you need an MVP, a new SaaS platform, or modernization of an existing product, I can work across architecture, backend, frontend, and infrastructure.
◆ MOBILE APP DEVELOPMENT
I build React Native mobile applications, including AI-powered apps, SaaS companion apps, and products that require secure APIs, real-time features, authentication, and complex backend integrations.
◆ CLOUD & PRODUCTION ENGINEERING
I work across AWS, Azure, and GCP using Docker, Kubernetes, CI/CD, microservices, and event-driven architectures.
I think about security, reliability, scalability, maintainability, and infrastructure cost before they become production problems.
◆ WHERE I’M MOST USEFUL
Fractional CTO, Solution Architecture, AI Agent Development, Generative AI, RAG & LLM Applications, Agentic AI, Multi-Agent Systems, MCP Integration, AI Automation, AI SaaS, SaaS Development, Full-Stack Development, Python & FastAPI, React & Next.js, React Native, API Integration, Cloud Architecture and Product Modernization.
If you need someone who can understand the business problem, make the architecture decisions, and still get hands-on with the engineering, send me a message with what you’re building and where you’re stuck.
I’ll help you choose the right approach and build it properly.
