I build production AI systems: RAG pipelines, LLM agents, and ML models that ship inside real products, not notebooks. Recent work: a citation-grounded RAG assistant (Claude API + pgvector) for a real-estate intelligence platform, and an XGBoost revenue-management system pricing thousands of daily airline flights. WHAT I DELIVER → RAG systems on your data: ingestion, chunking, embeddings, vector search (pgvector), and schema-validated, citation-grounded answers enforced in code so the model can't invent sources → LLM integration & AI agents: Claude and OpenAI APIs, tool use / function calling, agentic workflows, MCP servers, evals and guardrails → ML that earns money: demand forecasting, dynamic pricing, and valuation models (XGBoost, scikit-learn), containerized and retrained on schedule with Docker/Kubernetes → The full product around the AI: FastAPI or .NET backends, Vue/React frontends, PostgreSQL/PostGIS, auth, tests, CI/CD RECENT PROJECTS → LotScope (solo build): vacant-land intelligence platform. Async FastAPI, PostgreSQL + PostGIS + pgvector, Redis workers, Vue 3/Quasar frontend. Its "Ask the Parcel" RAG assistant answers zoning and feasibility questions with citations enforced by schema validation. → Airline revenue management (Japan): XGBoost models forecasting bookings, load factor, and ADR across thousands of daily flights; Kubernetes-scheduled retraining; pricing recommendations built on competitor and event signals. → Fortescue Metals "Catalyst": led migration of an enterprise portfolio platform to Vue 3 + .NET 9 with Snowflake pipelines, earned-value and financial tracking (22-month engagement). → King County Stormwater Planner: geospatial analysis across 90,000+ roads; 60% faster data loads through an intelligent caching layer.

Need a MERN stack developer who can turn a SaaS idea into a production-ready product? I build React, Next.js, and Node.js apps with the billing, roles, and dashboards real users actually need. Hi! I'm Waleed Saifi, a MERN stack developer with 6+ years building SaaS products with real product logic: billing, roles, dashboards, CRMs, messaging, APIs, reports, and workflows. I build and fix React, Next.js, Node.js, Express.js, MongoDB, and TypeScript apps that need to hold up under real production traffic. Most developers can build screens. The harder part is the system behind those screens: the data model, user permissions, payment flow, admin logic, API structure, third-party integrations, deployment setup, and the edge cases that only show up once real users start using the product. That's usually where I come in. I work best on SaaS platforms, internal tools, dashboards, CRMs, marketplaces, booking systems, real-time apps, and web/mobile products where the app is more than a basic frontend. Problems I regularly handle: - Turning a rough SaaS idea into a working MVP: frontend, backend, database, auth, payments, and deployment - Cleaning up React or Next.js apps that got hard to maintain - Fixing slow dashboards, broken APIs, unstable MongoDB queries, Stripe issues, auth bugs, and deployment failures - Building admin panels, user roles, subscription flows, notifications, messaging, reporting, and workflow automation - Integrating Stripe, Stripe Connect, Twilio, Google Maps, Firebase, OAuth, JWT, webhooks, and custom APIs - Adding AI-assisted features where they actually improve the product, not just because "AI" sounds good Recent product work: ▪️ WAWCD .com – SaaS CRM platform. Built with React, Next.js, Node.js, and MongoDB for 20K+ active users. Worked on CRM functionality, Stripe payments, Twilio messaging, and AI-assisted workflow automation. ▪️ Tournated .com – sports management platform. Built as a web platform and extended toward mobile, using Next.js, Node.js, MongoDB, and mobile-first product flows. ▪️ Prospeo .com – real estate SaaS platform. Built with React and Node.js for lead generation, data management, and AI-assisted property insights. Before writing code, I look at the product goal, user roles, database structure, API flow, payment logic, integrations, and deployment plan. Bad architecture early usually turns into expensive cleanup later, so I'd rather build it right from day one. I'm not the best fit for simple brochure sites or one-page landing pages. I'm a strong fit if you need a MERN stack developer who can take ownership of a real product, make technical calls, and ship features that hold up past the demo stage. Send me the app details, current stack, and what needs to be built or fixed. I'll come back with a practical technical plan.

I build production AI systems into full-stack platforms: RAG pipelines, LLM agents, OpenAI and Claude API integrations, and MCP servers, backed by Node.js, Python, and Next.js architecture that holds up under real users. Clients keep me long past the first milestone. My Upwork engagements regularly run past 500, 800, and 1,400 hours because I take ownership of the full stack and ship value within the first week, whether the codebase is greenfield or mid-flight. 𝗪𝗵𝗮𝘁 𝗜 𝗮𝗰𝘁𝘂𝗮𝗹𝗹𝘆 𝗯𝘂𝗶𝗹𝗱 AI-powered applications using OpenAI API, Claude API, LangChain, RAG pipelines, MCP integrations, AI agents, and custom document processing systems. Complex web platforms on Next.js, React, NestJS, Node.js, Python, and TypeScript. Marketplace platforms with matching engines, deal lifecycle workflows, and subscription management. Enterprise systems with role-based access control, audit logging, and Kubernetes deployments. Real estate, healthcare, and fintech platforms with Elasticsearch-powered search, automated analytics pipelines, and event-driven architecture. Full-stack SaaS products with multi-tenant architecture, tiered subscriptions, and production-grade data layers using PostgreSQL, Supabase, MongoDB, and Redis. 𝗣𝗿𝗼𝗱𝘂𝗰𝘁𝗶𝗼𝗻 𝗽𝗿𝗼𝗷𝗲𝗰𝘁𝘀 Hainok, an AI-powered real estate investment SaaS for the Spanish market. I worked across Next.js, NestJS, MongoDB, and Elasticsearch on AI investment scoring that surfaces the most profitable opportunities nationwide, automated ROI and cash flow analysis, geographic search and filtering, and a tiered subscription system built for scale. Finance Lobby, a commercial real estate financing marketplace on Next.js, Laravel, GraphQL, and PostgreSQL. AI-powered document parsing turned manual deal entry into automated structured submissions, feeding an algorithmic broker-to-lender matching engine. The platform today facilitates $40B+ in deals across 10,500+ verified lenders. Grip Facility, an AI-augmented contract management platform. I worked across the Next.js and TypeScript frontend with deep backend API integration, building AI-assisted workflows that help facility teams draft, review, and track contracts. Kliere, a HIPAA-aligned medical director oversight SaaS I built from scratch as the solo developer. Next.js, React, TypeScript, and Supabase with row-level security enforced at three layers, an 11-module compliance workflow, and a rule-based risk engine ending in signed weekly oversight reports. Gluu Inc., an enterprise IAM platform modernization: TypeScript migration, React architecture standardization, and authentication audit visibility across Kubernetes and VM environments for enterprise compliance teams. RCO and BREMOD, two production admin-panel systems I built end-to-end from scratch, covering inventory management, full order lifecycle, and operational reporting. 𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸 I integrate AI where it earns its keep, not as decoration. Prompt design, evals, latency, cost, and graceful fallback are part of the work, because a demo that impresses and a system that survives production are two different things. I do not start coding until I understand the architecture decisions that will be hardest to reverse. I set milestones, deliver working builds at each one, write documentation, and provide complete handoff support at close. Most of my engagements involve dropping into existing codebases mid-flight and shipping value within the first week. 𝗦𝘁𝗮𝗰𝗸 𝗔𝗜: OpenAI API, Claude API (Anthropic), LangChain, RAG systems, MCP servers, AI agents, Claude Code, Pinecone, document pipelines. 𝗙𝗿𝗼𝗻𝘁𝗲𝗻𝗱: React, Next.js, TypeScript, Vue.js, Angular, Tailwind CSS. 𝗕𝗮𝗰𝗸𝗲𝗻𝗱: Node.js, NestJS, Python, Django, FastAPI, GraphQL, REST APIs. 𝗗𝗮𝘁𝗮: PostgreSQL, Supabase, MongoDB, Redis, Elasticsearch. 𝗖𝗹𝗼𝘂𝗱: AWS, GCP, Docker, Kubernetes, CI/CD, GitHub Actions. Send me what you are building, and I will give you an honest read on the approach within a few hours.

I am a Senior Python and Cloud engineer with 7+ years of experience building high-performance systems. My core focus is delivering the complete package: robust Python/FastAPI backends, secure multi-cloud infrastructure (DevOps) and intelligent AI Agent workflows that actually solve business automation problems. Instead of just writing code, I bridge the gap between AI, data pipelines and scalable infrastructure. This means your AI apps will not just work in a local demo: they will scale seamlessly, run securely in production and keep cloud costs minimal. 💼 Domain Expertise & Business Impact I have built and scaled systems across Fintech, Edtech, Crypto, Retail and the Legal space. I specialize in deploying Agentic AI to automate complex, multi-step workflows that directly impact the bottom line: Fintech & Crypto: Built secure, low-latency transaction and trading backend systems, automating risk assessment and data ingestion pipelines while ensuring strict data compliance and cost efficiency. Legal Tech & Compliance: Developed autonomous AI Agents and advanced RAG pipelines to automate document analysis, contract extraction and legal research—cutting manual review times by up to 80%. Edtech & Retail: Designed intelligent recommendation engines and automated customer lifecycle workflows that increased user engagement and streamlined operations. 🚀 Production-Grade AI Agents & Backends I do not just call APIs; I build multi-agent systems, autonomous workflows and production-ready RAG pipelines that operate reliably under load. AI & Agentic Workflows: Designing autonomous AI Agents, tool executors and multi-agent orchestration. Hands-on with LangChain, OpenAI APIs and advanced RAG. Vector Search: High-performance similarity search using Qdrant, FAISS and Redis Vector. Backend Scale: Building low-latency RESTful and WebSocket APIs using Python and FastAPI (utilizing Asyncio for high concurrency). Distributed Workflows: Complex task management and AI pipeline orchestration using Celery and Redis. ☁️ Cloud Architecture & DevOps As an AWS Architect with extensive GCP and Azure experience as well, I build infrastructure that is automated, monitored and cost-optimized from day one. Infrastructure as Code (IaC): 100% automated deployments using AWS CDK, Terraform and CloudFormation. Containers & Serverless: Extensive work with AWS Lambda, ECS, EKS, Fargate, GCP Cloud Run and Kubernetes. CI/CD & Observability: Setting up robust deployment pipelines (GitHub Actions, AWS CodePipeline) and end-to-end monitoring (CloudWatch, Prometheus, Grafana). Cost Management: Active budget tracking, resource rightsizing and architecture reviews to stop cloud budget leaks before they happen. 📊 Data Engineering & Event-Driven Pipelines AI systems are only as good as the data feeding them. I build the pipelines that move and process your data efficiently. ETL/ELT Pipelines: Designing reliable data flows for batch and real-time workloads using PySpark and SQL. Streaming & Event-Driven Systems: Real-time data routing with AWS Kinesis, GCP Pub/Sub and Redis streams. 🤝 How We Can Work Together Clients usually bring me in when they need someone who can take full ownership of a technical challenge. Whether you need to build an autonomous AI agent to automate internal operations, spin up a secure cloud environment from scratch or scale an existing Python application, I deliver clean, documented and production-ready code. If you have a project that requires a mix of backend stability, DevOps automation and modern AI capabilities, send me a message and let's jump on a brief call to map out the architecture.

Clients come to me when something needs to work reliably and scale. I've spent the last few years building SaaS platforms, ETL pipelines, AI-powered tools, and automation systems in Python/Typescript, and I've managed dev teams without stepping away from the actual work. What I work on: 📊 Data Engineering and ETL: Pipelines that pull from APIs, databases, or scraped sources, transform and clean the data, and load it where it needs to go. I've worked with PostgreSQL, Redis, Neo4j, Google Sheets, and REST APIs as both sources and targets. 🤖 AI Integration: OpenAI API (GPT-4, embeddings, function calling, fine-tuning), Claude API via the Anthropic SDK, and Claude Code for agentic workflows. I build practical AI features into real products, not demos. Customer support bots, document processing, classification pipelines, and LLM-backed automation. ⚙️ Automation and Backend: Flask and FastAPI services, webhook handlers, Dockerised microservices, scheduled jobs, and anything that ties systems together. I handle full deployment cycles on Linux servers with Docker and docker-compose. 🕷️ Web Scraping: Anti-detection Selenium/Playwright with proxy rotation, multi-threaded Chrome profiles, dynamic content handling, and structured data output pipelines ready for downstream processing. 💬 Bot and Messaging Platforms: Telegram, Discord, Instagram (Graph API and automation), Facebook Marketplace, WhatsApp (Twilio and Meta API), and SMS workflows via Twilio. I build bots as part of larger systems tied to real-time data, alerts, CRMs, or user dashboards, not standalone scripts. I've led developer teams, written technical documentation, and delivered across fixed-price and long-term retainer formats. If you need someone who can scope, build, and own a data or automation project end to end, let's talk. 📚 Stack: Languages: Python, TypeScript, JavaScript, Rust, SQL Backend: FastAPI, Flask, Django, Node.js Frontend: React, Next.js, Tailwind CSS AI: OpenAI API (GPT-4, embeddings, function calling, fine-tuning), Anthropic Claude SDK, Claude Code, RAG Vector stores: pgvector, Pinecone, Chroma, Qdrant, Weaviate, FAISS Databases: PostgreSQL, Redis, Neo4j, SQLite, MySQL, MongoDB, Google Sheets API Scraping: Selenium, Playwright, proxy rotation, multi-profile Chrome, BeautifulSoup, Puppeteer Messaging: Telegram, Discord, Instagram Graph API, WhatsApp (Meta and Twilio), Twilio SMS Infra and DevOps: Docker, docker-compose, Linux, systemd, Caddy, Vercel, Railway, Hetzner, AWS, Git

AI SaaS MVPs and Platforms I build full-stack SaaS products from idea to launch: user accounts, dashboards, admin panels, role-based access, subscriptions, reporting, Stripe billing, notifications, and cloud deployment. I focus on clean architecture so the MVP can grow instead of needing a rewrite later. RAG and LLM Applications I build document intelligence systems, knowledge-base chatbots, structured extraction tools, and grounded AI assistants using OpenAI, Claude, embeddings, vector databases, LangChain/LangGraph, and custom retrieval pipelines. Secure Full-Stack Engineering My background in healthcare-grade and enterprise systems gives me a strong advantage when security, audit trails, access control, data privacy, reliability, and scalability matter. Core stack: React, Next.js, TypeScript, Node.js, Python, FastAPI, Nest.js, PostgreSQL, MongoDB, AWS, GCP, Docker, Kubernetes, OpenAI, Claude, LangChain, vector databases, Stripe, Twilio, REST APIs, GraphQL, and third-party integrations. Why clients hire me: I do not just build features. I help clarify the product, design the architecture, ship usable milestones, and make sure the system can survive real users, real data, and real business growth. If you are building an AI agent, SaaS MVP, RAG application, workflow automation platform, or secure full-stack product, I can help you turn it into a working production system.
