When your backend needs to scale, workflows need to run automatically, or you need Generative AI inside your product, that's where I come in. Python backend development, API integration, automation that ships.
A K-12 SaaS that saves teachers hours of manual grading weekly. A B2B logistics platform built on MERN that eliminated dispatch overhead and syncs Shopify, ERPs, and WMS in real time. A banking assistant that executes real transfers from a single sentence. A natural language interface that cut developer dependency for database reporting to zero. Those are my last four projects.

→ AI Automation and Agentic Workflows: If your team is still doing manually what a pipeline should handle, that is expensive. Autonomous multi-agent workflows built on LangChain, LangGraph, CrewAI, and n8n. BrokerBot AI handles real estate lead qualification around the clock, cutting response time by 60%. My LinkedIn outreach automation increased qualified leads by 4x and cut research time by 80%.
→ Generative AI Integration: AI features that work inside your product, not alongside it. RAG pipelines, document intelligence, AI chatbots, and natural language interfaces built on LangChain, OpenAI GPT-4, and Gemini. EdLoop, a K-12 AI SaaS, auto-generates personalized student feedback and surfaces district-wide insights, saving teachers hours of manual grading weekly with FERPA-compliant architecture.
→ RAG Pipelines and Natural Language Interfaces: Your data should not be locked away from the people who need it. Conversational interfaces over databases, documents, and knowledge bases using FAISS, Chroma, and LangChain. TALK2DATA lets non-technical teams query live PostgreSQL databases in plain English, zero SQL, zero developer dependency, zero waiting on reports.
→ SaaS Backend Development: Your backend should not be the reason your product cannot grow. Scalable API architecture on FastAPI, Django, and MERN, PostgreSQL and NoSQL databases, Stripe billing, webhook handling, and third-party integrations documented with OpenAPI. EtaFlex, a B2B last-mile SaaS, eliminated manual dispatch overhead and syncs Shopify, ERPs, and WMS in real time through event-driven n8n pipelines.

** TOP RATED PLUS | 100% Job Success | Senior Full-Stack AI Developer | AI SaaS Architect **
I am a Senior Full-Stack Developer with **10+ years of experience** building SaaS products, AI-powered applications, marketplaces, CRM/ERP systems, dashboards, APIs, and cloud-based platforms.
I usually work with startups and growing businesses where I’m expected to do more than complete tickets. I get involved in understanding the product, making technical decisions, building the frontend and backend, integrating external systems, deploying to production, and making sure the product remains reliable as it grows.
My core stack : ** Next.js, React, TypeScript, Node.js, NestJS, Python, Django, FastAPI, PostgreSQL, Supabase, AWS, Docker, and Kubernetes. **
### AI & LLM Development
A large part of my recent work involves building AI into real products rather than creating standalone chatbot demos.
I have worked with:
** OpenAI • Claude • Gemini • LangChain • LangGraph • RAG • AI Agents • MCP • Vector Databases • pgvector • Semantic Search • Document Processing • Structured Outputs • Tool Calling • AI Automation**
I build AI assistants, RAG and knowledge-base systems, document intelligence platforms, semantic search, agentic workflows, AI-powered SaaS features, and automations that connect LLMs with external APIs and business systems.
I also use ** Claude Code and Cursor ** in my daily development workflow. They help me move faster with implementation, debugging, testing, and refactoring, but I personally review and take responsibility for anything that reaches production.
### SaaS & Full-Stack Engineering
I have hands-on experience building:
• Multi-tenant SaaS platforms
• Authentication, RBAC & permissions
• Supabase RLS & tenant isolation
• CRM & business workflow systems
• Marketplace & booking platforms
• Stripe subscriptions & payments
• Admin/customer portals
• Dashboards & reporting
• Background jobs & automation
• Audit logs & approval workflows
• Real-time applications
• REST APIs, GraphQL & WebSockets
I’m comfortable starting a product from scratch, working from an existing PRD/technical specification, or taking over an existing codebase that needs to be fixed, refactored, or scaled.
### Technology
**Frontend:**
Next.js, React, TypeScript, JavaScript, Tailwind CSS, shadcn/ui, Redux, Zustand, Vite
**Backend:**
Node.js, NestJS, Express.js, Python, Django, FastAPI
**Database:**
PostgreSQL, Supabase, MySQL, MongoDB, Redis, pgvector
** Cloud & DevOps z:**
AWS, Vercel, GCP, Docker, Kubernetes, GitHub Actions, GitLab CI/CD, EC2, Lambda, S3, RDS, CloudFront
### APIs & Integrations
A lot of my work involves connecting products with external systems, ** Stripe, Twilio, Google APIs, CRM platforms, OAuth services, email/SMS providers, payment systems, webhooks, and third-party REST APIs. **
I pay particular attention to the things that usually cause problems after launch: expired OAuth tokens, duplicate webhooks, retries, rate limits, partial failures, bad payloads, idempotency, and external service downtime.
### How I Work
After 10+ years in development, I’ve learned that good engineering is usually about keeping things clear and dependable.
I prefer simple architecture over unnecessary complexity. I ask questions when requirements aren't clear rather than guessing. I won't recommend rebuilding something when a proven API or service already solves the problem well.
If I inherit an existing application, I understand it before changing it. If I see a security, scalability, or maintenance problem, I raise it early.
And I don't consider something finished just because it works locally, ** testing, deployment, monitoring, security, performance, and failure handling are part of delivering the feature.**
### Certifications
• AWS Developer Associate
• Certified Kubernetes Administrator (CKA)
• Docker Certified Associate
• GCP Cloud Engineer
• GitLab CI/CD Professional
• MongoDB Certified Developer
• DevOps Certified Engineer
• Certified API Professional
I’m a strong fit for **AI SaaS, AI Agents, B2B SaaS, marketplaces, CRM/ERP platforms, workflow automation, API-heavy applications, and products that need experienced technical ownership.**
**Available for Fixed-Price & Hourly Projects**
**Open to Long-Term Product Partnerships**
