"Your SaaS platform is 99% done." Real-time data doesn't work. API integrations fail under load. AI functionality was added but never connected to real data. Works for 10 users. Breaks at 1,000. The full-stack developer is gone. The pre-deployment audit says: start over.
My Clients never tell this story.
⭐ Top Rated Plus ⭐ 100% Job Success ⭐ 92% client retention ⭐ 8 years in the game
⭐ 3M+ unique users in production ⭐ 200K+ monthly active users ⭐ 37+ AI-powered solutions
I'm a full-stack developer specializing in SaaS platform development, Node.js, Python, and API integration. I build healthcare platforms, AI assistants, AI automation platforms, fintech systems, B2B SaaS applications, and enterprise integrations. Multi-tenant SaaS platforms, backend APIs, cloud infrastructure, and AI integrations using OpenAI API, Claude API, LangChain, and RAG architectures. Every SaaS platform I deliver is production-ready - scalable from day one, not rebuilt in six months.
Here's how I prevent each of those:
🔴 "99% done"
I define done as production-ready. A SaaS platform isn't finished until it's load-tested, edge cases are handled, and your team can maintain it. No surprises after handover.
📡 Real-time data
I architect the real-time data layer from the start, not as an afterthought.
WebSockets, event-driven systems, live dashboards that actually update when your data does.
🔌 API integrations
I build every API integration with error handling, retry logic, rate limiting, and monitoring built in.
When a third-party updates their endpoints, your SaaS platform keeps running.
🤖 AI functionality
I connect AI to your actual business data, not a feature floating above your product.
RAG systems, OpenAI API, Claude API, LangChain - embedded in the data layer where it creates real value.
📈 Scalability
Every SaaS platform I build is designed for 10x your current load from day one. Multi-tenant architecture, database optimization, cloud infrastructure that grows without a rebuild.
👤 The full-stack developer disappears
92% of my clients return for the next project.
Full documentation, knowledge transfer, and ongoing support are part of how I work.
✅ Pre-deployment — I deliver code that passes any audit. Architecture reviews, performance testing, and security checks are part of the build, not a last-minute discovery.
What I build:
🏗️ SaaS Platforms
Multi-tenant architecture, subscription management, role-based access control, B2B SaaS applications
🔌 API & Backend Development
Node.js, NestJS, Python, FastAPI, REST API, GraphQL, microservices, API integration with third-party services
🤖 AI Integration
RAG systems, AI agents, OpenAI API, Claude API, LangChain, LLM integration, AI-powered automation
☁️ Cloud Infrastructure
AWS, Docker, Kubernetes, serverless, cost-effective high-performance architecture
📊 Data-Driven Dashboards
Real-time analytics, financial reporting, BI migration, data visualization, Customer 360
🔄 Automation & Workflows
WhatsApp Commerce platforms, n8n, Zapier, custom automation pipelines
🛡️ Enterprise Integrations

⚙️ Tech Stack: NestJS, FastAPI, React, Next.js, TypeScript · AWS, PostgreSQL, MongoDB, Redis

Senior Python backend developer with 10+ years building scalable SaaS platforms, REST APIs, and AI-powered systems in Python, Django, DRF, and FastAPI. I turn product requirements into clean architecture, reliable integrations, and production-ready delivery.
Need someone to own the backend — from database and API design to LLM integrations and deployment? That's my core strength. I focus on backend-heavy web applications where reliability, maintainability, and business logic matter most, and I help teams fix slow, messy, or hard-to-maintain Python/Django codebases by restructuring logic, stabilizing APIs, and cutting technical debt.
I also deliver end-to-end SaaS MVPs — integrations, admin flows, auth, deployment, and collaboration across the full web stack.
𝗪𝗵𝗮𝘁 𝗜 𝗯𝘂𝗶𝗹𝗱:
🟢 SaaS backends and MVPs (Django / DRF, FastAPI)
🟢 REST APIs, webhooks, and third-party integrations
🟢 AI & LLM features — OpenAI, Claude, LangChain, LangGraph, RAG
🟢 Workflow automation and ETL pipelines (Celery, Redis)
🟢 Admin panels, authentication, roles & permissions
🟢 Refactoring & scaling legacy Python / Django systems
🟢 Docker-based deployment, AWS, and CI/CD
𝗖𝗹𝗶𝗲𝗻𝘁𝘀 𝗵𝗶𝗿𝗲 𝗺𝗲 𝘁𝗼:
🟢 Launch the backend for a new SaaS product
🟢 Stabilize and scale an existing Django application
🟢 Build APIs and integrations that scale reliably
🟢 Automate manual business workflows
🟢 Add AI / LLM functionality to an existing platform
🟢 Get senior-level execution without unnecessary complexity
𝗘𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲:
Over 10+ years I've shipped products across SaaS, fintech, healthcare, education, and internal business tools. I build modular, well-structured systems that stay easy to extend as your product grows — especially strong in API-heavy platforms, async workflows, and third-party integrations.
𝗖𝗼𝗿𝗲 𝘀𝘁𝗮𝗰𝗸:
Python · Django · Django REST Framework (DRF) · FastAPI · PostgreSQL · MySQL · Celery · Redis · Docker · AWS · GitLab CI/CD · REST APIs · Webhooks · Stripe · Twilio · OpenAI · Claude · LangChain · LangGraph · React
𝗛𝗼𝘄 𝘄𝗲 𝘀𝘁𝗮𝗿𝘁:
For projects where the scope needs validation, I offer a paid discovery phase — a practical way to align on architecture, priorities, and a delivery plan before a larger engagement. You leave with a clear roadmap, fixed next steps, and no guesswork.
If you need a solid Python/Django backend, clean APIs, AI integrations, and senior-level execution with clear communication, send me a message — I'll reply with honest feedback on your project.

I build and improve practical software systems for businesses, including full-stack web apps, automations, AI tools, integrations, dashboards, customer-intake flows, and operational workflows.
My strength is taking a business problem, understanding the moving pieces, and turning it into a working technical system. That may mean building from scratch, fixing an inherited project, connecting APIs, improving a website, automating a workflow, cleaning up a database, or integrating tools across a company’s existing stack.
I work across modern web, automation, AI, CRM, payment, communication, and data tools. Recent work has involved platforms, codebases, and tools such as React, Python, JavaScript/TypeScript, Supabase, Stripe, Twilio, Retell, Make .com, n8n, APIs, webhooks, and LLMs. I’m also comfortable adapting across broader stacks and business platforms, including Django, HubSpot, GoHighLevel, WordPress, CRMs, internal tools, and similar systems.
Clients hire me because I diagnose before I build, communicate clearly, explain tradeoffs honestly, and focus on systems that are reliable, maintainable, and useful in the real world.
What I can help with:
• Full-stack web apps, dashboards, portals, and business tools
• Workflow automations, APIs, webhooks, and backend integrations
• AI voice agents, chatbots, intake systems, and LLM-powered tools
• CRM, payment, phone/SMS, calendar, email, and operational workflows
• Data pipelines, reporting workflows, and internal business systems
• Website improvements, launch-readiness fixes, and inherited-project cleanup
• Security, OAuth, deployment, documentation, and handoff improvements
Credentials and proof:
• 100% Job Success Score on Upwork
• University of Maryland certification
• Anthropic Academy certifications listed in my profile
• Make .com Advanced Certified
• Camunda BPMN Certified
• Strong client feedback for communication, reliability, problem-solving, and delivery quality
If you need a practical technical builder who can understand the problem, choose the right approach, and deliver a working system, send me the details. I’ll tell you what I recommend, what it will take, and whether I’m the right fit.
