Abdul Saboor K.

I help founders, product owners, and growing teams build, stabilize, and extend SaaS products, AI-enabled software/platforms, and business automation systems. 10+ years on Upwork · 4,000+ hours · $200K+ delivered Whether you need to build the next version of a SaaS platform, take an AI-assisted prototype into production, automate operational workflows, or stabilize an existing codebase, I work as a senior product engineer who thinks beyond the ticket and takes ownership of the outcome. 𝗛𝗼𝘄 𝗜 𝗖𝗮𝗻 𝗛𝗲𝗹𝗽 SaaS & Product Development: Build and extend SaaS platforms, marketplaces, customer portals, internal tools, and mobile products across frontend, backend, database, auth, payments, APIs, and deployment. AI Automation & Integrations: Automate business workflows using n8n, Make, Zapier, OpenAI/Claude, APIs, webhooks, CRMs, messaging systems, Shopify, and custom backend logic, especially when no-code tools alone are not enough. Prototype to Production: Have something built with Lovable, Replit, Cursor, Claude Code, or another AI-assisted workflow? I can audit the existing system, preserve what works, address fragile architecture, and prepare it for real users without defaulting to a rebuild. Existing Product Takeover & Stabilization: I work comfortably inside existing React, Next.js, Node.js, Supabase, PostgreSQL, Python, and API-based systems, understanding the current architecture first, then making focused improvements. AI Product Features LLM workflows, RAG, structured outputs, document processing, AI-assisted user experiences, agents where appropriate, and human-reviewed AI workflows. 𝗛𝗼𝘄 𝗜 𝗪𝗼𝗿𝗸 I focus on practical product engineering: • Understand the business workflow before adding complexity • Build architecture appropriate for the product’s current stage • Preserve working systems instead of rewriting unnecessarily • Use AI-assisted development to accelerate implementation • Review critical architecture and engineering decisions personally • Work through clear milestones, working demos, QA, and acceptance criteria • Keep the codebase understandable and maintainable for the next engineer AI accelerates implementation. Engineering judgment still owns the outcome. 𝗣𝗿𝗼𝘃𝗲𝗻 𝗣𝗿𝗼𝗱𝘂𝗰𝘁 𝗪𝗼𝗿𝗸 ZeitFilter: Production-ready marketplace, live on web and published across app stores. Jokester: Live streaming and ticketing platform for stand-up comedy. Scrive: AI-native HR SaaS, successfully delivered through internal beta. Confidential AI MVP (NDA): Multiple production phases delivered. 𝗧𝗲𝗰𝗵𝗻𝗼𝗹𝗼𝗴𝘆 Product Engineering: React · Next.js · TypeScript · Node.js · Express · NestJS · React Native / Expo · Python / FastAPI Data & Infrastructure: Supabase · PostgreSQL · RLS · Prisma · Drizzle · AWS · Vercel · Docker AI: OpenAI · Anthropic Claude · RAG · pgvector · LangChain · LangGraph · Structured LLM Workflows · MCP Automation & Integrations: n8n · Make · Zapier · Stripe · Twilio · Shopify · Webhooks · REST APIs · GraphQL 𝗡𝗲𝘅𝘁 𝗦𝘁𝗲𝗽 If you already have a product, prototype, workflow, or system that needs to move forward, send me the current state and the outcome you’re trying to reach. I’ll help determine whether the right next step is to build, stabilize, integrate, automate, or simplify.
