Project details
Launching a professional web or mobile application demands more than just functional components—it requires clean, scalable code, responsive layouts, and performance optimization. Many businesses face challenges with inconsistent UI, slow page loads, and fragmented user experiences, which can hinder growth and user satisfaction.
I provide full frontend development using React, Next.js, React Native, Tailwind CSS, and Material-UI (MUI) to deliver polished, responsive, and maintainable applications. From building individual pages to multi-page web apps or mobile interfaces, I focus on creating reusable components, scalable architecture, and cross-platform compatibility.
Whether you need a startup MVP, a growing product upgrade, or a fully-featured frontend, I ensure your application is fast, modern, and future-proof. My deliverables include responsive layouts, clean styling, API integrations, and thoroughly tested code, ensuring your users enjoy a seamless experience across devices.
Let’s build your full-featured frontend solution with modern technologies and design systems, delivering a high-quality, scalable, and performance-optimized application that meets your business goals.

Job Success
Toronto, Canada - 3:00 pm local time
I specialize in fixing and preventing those failures.
I am a Senior Full-Stack Architect with 7+ years of experience building, scaling, and rescuing production-grade applications across SaaS platforms, enterprise systems, and AI-powered products. My work spans architecture design, full-stack implementation, system integration, and production hardening using React, Next.js, Node.js, Python, and modern AI frameworks.
My focus is not task execution, it is system ownership. I help teams move from MVP to scalable production systems, integrate complex APIs and AI capabilities, and restructure broken or incomplete applications into maintainable, production-ready platforms.
Core Expertise
SaaS Architecture and Full-Stack Systems
I design and build scalable SaaS platforms with strong architectural foundations, including:
Multi-tenant system design using Supabase and PostgreSQL with Row Level Security
Scalable frontend architecture using React and Next.js (App Router, SSR, ISR, caching strategies)
Backend development using Node.js, NestJS, and Express with modular service design
API orchestration layers using Backend-for-Frontend patterns, REST, and GraphQL
System design focused on scalability, maintainability, and multi-team development
I have worked on systems where multiple engineering teams deploy independently into a shared platform without breaking stability, achieved through Micro Frontend architecture and centralized shell design.
AI Systems and LLM Integration
I build production-ready AI systems embedded directly into real products, not prototypes.
LLM integration using OpenAI, Claude, Gemini, and open-source models
Retrieval-Augmented Generation (RAG) pipelines using LangChain and LlamaIndex
AI agent workflows for automation, reasoning, and tool execution
Vector database implementations using Pinecone, Weaviate, and ChromaDB
Real-time AI systems using WebSockets and streaming responses
AI cost optimization, prompt design, and failure handling strategies
My focus is building AI systems that are reliable under real production usage, with proper grounding, fallback logic, and scalable architecture.
Production Rescue and Legacy System Fixing
A significant part of my work involves taking incomplete, broken, or poorly structured applications and turning them into production-ready systems.
This includes:
Cursor, Bolt, Lovable, and v0-generated applications that have hit architectural limits
SaaS MVPs that function partially but cannot scale
Codebases with weak structure, missing backend logic, or poor separation of concerns
Frontend-heavy applications lacking proper API or database design
I perform system audits, identify structural issues, and refactor or rebuild only what is necessary to make systems stable, scalable, and maintainable without unnecessary full rewrites.
Technical Stack
Frontend: React, Next.js, TypeScript, Tailwind CSS, Shadcn/UI, Redux Toolkit, Zustand, React Query

Databases: PostgreSQL, MySQL, MongoDB, Supabase
AI / LLM: OpenAI API, Claude API, Gemini API, LangChain, LangGraph, LlamaIndex, RAG pipelines, vector databases
Infrastructure: AWS, Vercel, Docker, CI/CD pipelines using GitHub Actions
Testing: Jest, Cypress, Playwright, React Testing Library
Enterprise Aviation Platform – Designed a Micro Frontend architecture using Webpack Module Federation enabling independent team deployments with a centralized shell for routing, auth, and shared state. Built a Backend-for-Frontend layer integrating REST and GraphQL APIs.
Preplify – Built a full-stack AI SaaS using Next.js with OpenAI and Gemini integrations, WebSocket-based real-time AI responses, and performance optimization via SSR/ISR.
Cyber Mart – Optimized a high-traffic Next.js SSR marketplace achieving 95+ Lighthouse scores and improved database performance by 40% through indexing and schema optimizations.
Who I Work Best With
SaaS founders moving from MVP to scalable production systems
Engineering teams needing architecture leadership and system design support
Startups building AI-powered applications with real-world integration requirements
Teams facing scaling issues, technical debt, or fragmented systems
Founders with partially built or “vibe-coded” applications requiring production-grade restructuring
Working Style
I operate as a system-level engineer. I first analyze architecture, constraints, and scalability requirements before implementation.
Clients can expect:
Clear architectural direction before execution
Honest assessment of system limitations and risks
Maintainable, scalable code structure
Consistent communication throughout delivery
Focus on production stability, not just feature completion
