Top Rated full-stack AI engineer (68 jobs, 100% JSS, 2,000+ hours on Upwork) with 6+ years building production AI systems for manufacturing, FMCG, and operations clients. I ship full SaaS products end-to-end — backend, frontend, AI features, deployment — not prototypes. I build the whole thing. I am a full-stack AI engineer with 6+ years of real business experience inside manufacturing, FMCG, and operations at Coca-Cola, Singer Bangladesh (Arçelik), Walton Hi-Tech. I have been on the client side of broken tools and bad data. Now I build the systems I wished existed. What makes me different from most full-stack freelancers: I can ship your React frontend, wire it to a FastAPI backend, connect it to PostgreSQL, add an AI agent or LLM feature, deploy it to AWS or Vercel — and I understand the business problem well enough to tell you when you are overbuilding. → SAAS MVP DEVELOPMENT This is my primary focus. If you are a founder who needs a working product in 2–4 weeks, this is what I deliver: → React / Next.js frontends — clean, responsive UI built for real users, not just demos. Tailwind CSS, component libraries, smooth UX. → FastAPI or Node.js backends — REST APIs with proper auth (JWT/OAuth), rate limiting, error handling, and documentation your team can actually use → Database design — PostgreSQL with a schema that won’t break when you hit 10,000 users. Migrations, indexing, query optimization. → Full deployment — Vercel for frontend, AWS EC2 or Railway for backend, environment configs, CI/CD with GitHub Actions. You get a live URL, not a zip file. → Stripe integration — subscription billing, usage metering, webhook handling, customer portal. Revenue from day one. → Auth systems — user registration, login, roles and permissions, password reset, email verification. Done properly, not hacked together. → AI & AGENTIC FEATURES FOR YOUR SAAS Most SaaS products in 2025 need at least one AI feature. I build them as production-ready components, not demos: → AI agents built with LangChain and LangGraph — autonomous workflows that research, extract, decide, and deliver structured outputs inside your product → RAG document systems — users upload files, ask questions, get answers with citations. Customer support, internal knowledge bases, legal document review. → LLM-powered data extraction — turn unstructured inputs (emails, PDFs, forms) into clean structured data your database can store → Automation pipelines — Airflow or Celery workers that run background jobs, send alerts, process queues, and keep your product running while nobody is watching → DATA & ANALYTICS LAYER → Power BI and Looker dashboards embedded in your product or delivered standalone — connected to live data, auto-refreshing, built for decision-making not decoration → ETL pipelines — multi-source data ingestion into PostgreSQL or data warehouses, replacing manual work permanently → ML prediction APIs — demand forecasting, churn scoring, recommendation engines — FastAPI endpoints your product can call in real time WHO I WORK WITH Founders building a SaaS MVP who need one engineer who can own the full stack — frontend, backend, AI, and deployment — without managing 4 different freelancers. Startups that have a working product but need to add AI features, improve performance, or fix the architecture before scaling. Operations and manufacturing businesses that need internal tools, dashboards, or automation systems built properly. Small teams where budget matters — you need someone who makes good decisions independently, not someone who needs constant direction. WHAT I HAVE DELIVERED ✓ Full-stack SaaS starter — Next.js frontend, FastAPI backend, PostgreSQL, JWT auth, Stripe billing hooks, rate limiting, deployed on AWS. Used as a base for client products. ✓ RAG document assistant — React UI, FastAPI backend, LangChain + ChromaDB pipeline, deployed on Vercel + EC2. Users upload PDFs, ask questions, get cited answers. ✓ LLM automation agent — searches the web, reads documents, queries a database, writes structured reports to Slack. Replaced 3 hours of manual work per week. ✓ Commercial analytics at Coca-Cola Icecek — sales data systems driving strategic decisions in a high-volume FMCG environment ✓ Quality data systems at Singer Bangladesh

Looking for a QA Engineer who can deeply test your SaaS product, uncover hidden edge cases, and ensure smooth, release-ready deployments? You’re in the right place. ✅ I’m Khorshed, a Manual QA Engineer with 3+ years of experience testing SaaS platforms, AI applications, and complex workflow-driven web apps. I have tested platforms across SaaS, AI, Fintech, LegalTech, Healthcare, EdTech, Insurance, and Social platforms. Analytical thinking is one of my strongest QA skills. I quickly understand product workflows, user roles, and system dependencies, which helps me identify high-risk areas and hidden edge cases early. Instead of only testing happy paths, I think like a real user and actively explore misuse scenarios, permission boundaries, and workflow breaks. To ensure nothing is missed, I create a structured feature × role × environment testing matrix that maps every important functionality. This approach helps uncover logic gaps, access issues, and edge cases before release, which is especially critical for complex SaaS platforms. Core QA Expertise: - SaaS Product Testing - Role-based access testing (Admin / Super Admin / User / Approver) - Multi-tenant platform validation - Workflow & business logic testing - Feature branch testing before release - Release readiness validation Testing Types: - Functional Testing - Regression Testing - Smoke & Sanity Testing - Exploratory Testing - Edge Case Testing - Database & Data Validation - Integration Testing - Cross-Platform Testing Web: Chrome, Safari, Firefox, Edge Mobile: iOS / Android Desktop environments QA Documentation & Reporting: - Test Plans - Test Scenarios & Test Cases - Regression Suites - Bug Reports with reproduction steps - Severity & priority classification - Release validation reports Tools I Work With: - Jira - Github - Basecamp - ClickUp - Trello - TestRail - Airtable - Azure DevOps - Notion - Google Sheets QA trackers - Loom / Screenshots for bug documentation My SaaS Testing Approach: I follow a structured QA workflow used by product teams and startups. 1️⃣ Requirement Analysis: Review feature specs, workflows, and acceptance criteria to identify missing edge cases and logic gaps. 2️⃣ Test Planning: I create a coverage matrix (Roles × Features × Environments) in a spreadsheet to ensure no scenario is missed. 3️⃣ Test Execution: I perform deep exploratory testing, simulating real user behavior such as: - incorrect inputs - skipped steps - permission boundary testing - workflow misuse scenarios - URL manipulation attempts - UI logic validation 4️⃣ Bug Reporting: Clear, developer-friendly bug reports including: - Clear bug title - Steps to reproduce - Expected vs actual behavior - Screenshots / recordings with voice - Severity classification - Console errors when relevant 5️⃣ Regression Testing: Before each release I verify that new fixes do not break existing functionality. 6️⃣ Release Validation: Final smoke testing and release readiness checks before production deployment. SaaS Platforms & Products I’ve Tested: NFPhub (SaaS Project Management Platform) → - Multi-tenant system - Role-based access (Admin, Approver, User) - Tested 10+ testing cycles before launch - Integration testing with MS Teams & Google Calendar - Maintained bug tracking sheets until resolution - Provided UI/UX improvement suggestions Appara (LegalTech SaaS Platform) → - Document-heavy legal workflow platform - Tested data-driven modules and document workflows - Verified system logic across complex features Notch (Project Management SaaS) → - Tested collaboration workflows - Permission and access validation - Feature regression testing PhysicianUX → AI healthcare platform for doctors CrashClaim → AI-powered insurance chatbot JavelinAI → AI email management platform SunlightAI → AI-powered EdTech platform (Prompt Engineering) TharejaAI → AI project management tool In some projects I also contributed to prompt engineering and frontend improvements while testing AI-driven features.
