About Naresh
Solution Architect for SaaS & AI Startups | MERN, Cloud, MVPs

Job Success
Delhi, India - 8:37 pm local time
I'm a Solution Architect for SaaS and AI startups. I design systems that work today, scale tomorrow, and don't trap you in technical debt later.
❝The best architecture is the one you don't have to rewrite. Discipline upfront saves you the rewrite later.❞
Why Founders & CTOs Hire Me
I've spent 8+ years architecting and shipping production systems for SaaS platforms, marketplaces, fintech products, and AI applications. I've seen what breaks at scale and what holds. I bring that pattern recognition to your stack before the problems become expensive.
I work as your architect, not your contractor. I make the decisions that matter: stack selection, data model, multi-tenancy strategy, AI integration patterns, scaling path. Then I either ship it myself or lead your team through the build.
Track Record⭐ Top Rated on Upwork | 100% Job Success 🚀 8+ years shipping production systems 💯 100+ projects delivered, $100K+ earned, 8,000+ hours logged
Where I Add the Most Value
✔ Pre-seed to Series A founders who need a senior technical voice before committing to a stack ✔ CTOs who need an architecture review or second opinion on a critical design decision
✔ Teams stuck on scaling problems: slow queries, broken multi-tenancy, AI cost blowouts
✔ Agencies and offshore teams that need senior architectural oversight
✔ Founders preparing for fundraising or technical due diligence
Engagement Models
🔸 Architecture Design (1 to 3 weeks): I diagnose your problem, design the system, deliver documentation, and hand off to your team.
🔸 Embedded Architect (10 to 20 hrs/week): I lead architecture decisions across an active build, review code, and unblock your team.
🔸 Tech Audit & Rescue: Fixed-scope review of a stalled or broken build with a clear remediation plan.
🔸 MVP Build + Foundation (3 to 6 weeks): I architect AND ship your v1 on a stack built to scale.
Core Architectural Specialties
✅ Multi-tenant SaaS architecture (data isolation, billing, scaling)
✅ AI system design (RAG pipelines, agent workflows, LLM integration patterns)
✅ Event-driven architecture and async processing
✅ API design (REST, GraphQL, webhooks, integrations)
✅ High-volume data pipelines and real-time processing
✅ Cloud architecture on AWS, GCP, Vercel
✅ Database design (PostgreSQL, MongoDB, vector stores)
✅ Microservices and modular monolith trade-offs
✅ Authentication, authorization, and tenant security
✅ CI/CD, containerization, and deployment strategy
Common Pitfalls I Help You Avoid
The early stage tempts overengineering. I keep your architecture aligned to your actual stage, not where you wish you were. That means:
✘ No premature microservices when a modular monolith would ship faster
✘ No exotic stacks chosen for the resume instead of the problem
✘ No 100% test coverage targets that slow down learning
✘ No AI integration patterns that burn cash without delivering value
✘ No frameworks you'll regret in 18 months when you need to hire
The right architecture is the simplest one that gets you to the next milestone. Everything else is vanity.
Tech Stack I Architect With
Frontend: React, Next.js, TypeScript, Tailwind Backend: Node.js, NestJS, Python (FastAPI), Laravel Mobile: React Native, Expo Databases: PostgreSQL, MongoDB, Redis, Supabase, Pinecone Cloud: AWS, GCP, Vercel, Docker AI: OpenAI, Claude, LangChain, RAG, vector embeddings Integrations: Stripe, Twilio, OAuth, REST, GraphQL, webhooks
I'm stack-agnostic when the problem allows it. I recommend what fits your stage and team, not what's trending on Hacker News.
