Job Success
Jammu, India - 7:47 pm local time
I help startups, SaaS teams, 3PL Ops Managers and operations-focused businesses build, improve, and scale AI-enabled applications, workflow automation systems, dashboards, marketplaces, and internal tools. With 5+ years of experience, I work across React, NextJS, TypeScript, NodeJS, Python, C#/.NET, Golang, API integrations, PostgreSQL, Supabase, Stripe, authentication, billing, and backend workflows.
I bring around 6 years of full-stack development experience across frontend interfaces, backend systems, databases, integrations, authentication, billing, and production support.
HOW I CAN HELP
• Build SaaS MVPs and production features
• Improve, debug, and stabilize existing applications
• Develop AI assistants, RAG search, document extraction, and classification workflows
• Automate repetitive business processes using APIs, webhooks, queues, and n8n
• Build 3PL, logistics, fulfillment, inventory, order, and shipping workflows
• Integrate payment gateways, subscriptions, Stripe billing, OAuth, and external APIs
• Develop dashboards, admin portals, role-based access, and multi-step workflows
• Implement background jobs, notifications, real-time updates, and reliable retry handling
• Build marketplace, CRM, LMS, reporting, and internal operations software
CORE TECHNOLOGIES
React, NextJS, TypeScript, JavaScript, NodeJS, NestJS, Express, Python, FastAPI, C#/.NET, Golang, PostgreSQL, MySQL, MongoDB, Supabase, REST APIs, GraphQL, Stripe, OAuth, Redis, BullMQ, Socket IO, Docker, AWS, Vercel, n8n, OpenAI API, RAG, and webhooks.
BEST-FIT PROJECTS
• AI SaaS and workflow automation products
• 3PL, logistics, fulfillment, and operations software
• Existing SaaS applications requiring improvements or new features
• API and third-party platform integrations
• Marketplaces and search-based products
• CRM, LMS, admin, and management portals
• Document processing and approval workflows
• Subscription and customer-retention platforms
HOW I WORK
I first understand the existing codebase, product flow, and business rules. I then divide the work into small, testable milestones with clear deliverables.
I prioritize maintainable code, reusable components, dependable backend logic, resilient integrations, and concise asynchronous communication. Features, major migrations, architecture changes, and complex integrations are clearly scoped before implementation.
If you need help with full-stack SaaS development, AI integration, workflow automation, API integrations, or improving an existing application, send me your current stack, main problem, desired outcome, and deadline.
I’ll review the requirements and suggest a practical first milestone.
