I'm an independent full-stack developer with 10+ years of experience shipping production systems in Node.js, React, Angular, PHP, CakePHP, CodeIgniter, Yii2, Symfony and Laravel. I work directly with founders and engineering teams — no agency middlemen, no project managers in between. You talk to the person writing the code. Project Delivered - 1. Multi-channel eCommerce APIs integration-based SAAS tool for online stores management - description, inventory, orders, delivery etc. 2. Transportation CRM for a vehicle moving company. 3. ERP system for the repair business 4. Pateron API-integration-based secure membership portal for content creators with a custom player. 5. FedEx, USPS, DHL, Canadapost integration-based shipping price comparison portal. Where I add the most value: → Backend & APIs — Node.js (Express) REST services, database design (PostgreSQL, MySQL, MongoDB), authentication, payments, third-party integrations. → Full Stack Web Apps — End-to-end builds with React or Angular on the front end and Node.js or Laravel on the back. Comfortable owning a project from architecture through deployment. → Legacy Modernization — Migrating older PHP codebases (CodeIgniter, Yii2) to Laravel or Node.js without breaking what works. My mixed background actually pays off here — I read old code fluently. → CMS & E-commerce — Custom WordPress plugins and themes, Prestashop and OpenCart development, and performance optimization for stores with real traffic. How I work: I respond to messages within the hour during your business day. I scope before I quote. I write clean, documented code, ship in small reviewable chunks, and flag scope risks early — before they become problems, not after. Availability: 40 hours/week, full-time freelance, available for audio/video interviews. If you have a project in mind, send a message describing what you're trying to build or fix and any timeline constraints. I'll reply with honest thoughts on scope and approach before we discuss pricing.

You're building a SaaS platform or AI product. You have a developer or agency, but you're not sure the architecture will hold up at 10x scale. Or you're about to commit to a stack, and the wrong choice now will cost you six months and $100K to undo. 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. Industries SaaS · Fintech · Healthcare · CPG · Manufacturing · Supply Chain · Logistics · ERP/CRM · Human Capital Management · Real Estate · Banking/NBFC Specialised Use Cases ✔ Multi-tenant SaaS platforms ✔ AI Chatbot & Agent Systems (RAG, customer support, lead gen) ✔ AI Automation & Workflow Engines ✔ AI Demand Forecasting (CPG, supply chain, retail) ✔ Warehouse Management Systems (WMS, inventory, fulfilment) ✔ Cargo & Logistics Platforms ✔ Custom ERP & CRM Builds ✔ Compliance-aware Healthcare Platforms Send me your architecture question or your current system diagram.
