Hello, I’m Md. Bulbul Islam, a seasoned Data Analyst and Research Specialist with over 14 years of experience in national and international development and academic organizations. I previously served as a Data Analyst at BRAC University, one of the leading private universities in Bangladesh. I hold a Bachelor's and Master's degree in Education Research from the National University of Bangladesh, an MBA in Human Resource Management from ASA University, and a Master's in Applied Statistics and Data Science from Jahangirnagar University. Additionally, I have completed the Google Data Analytics Professional Certificate, further strengthening my technical and analytical capabilities. Throughout my career, I’ve built deep expertise in research design, quantitative and qualitative data analysis, and digital data collection. I specialize in tools like KoboToolbox, SurveyCTO, SPSS, Stata, Excel, R, and Python. I’ve also published four research papers in international journals and regularly contribute as a trainer and capacity-building consultant. I am now seeking freelance and / or remote opportunities where I can apply my research, data, and training skills to drive evidence-based decision-making and innovation.

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

𝗪𝗲𝗯 𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻 & 𝗪𝗲𝗯 𝗦𝗰𝗿𝗮𝗽𝗶𝗻𝗴 : I build resilient, production-ready automation and scraping systems that reliably collect the data your team needs. Practically, that means designing scrapers with robust retry logic, anti-bot handling, structured output (CSV/Excel/DB), and monitoring so data pipelines don’t break when sites change. Manual data collection is eliminated, reporting becomes timely and accurate, and teams stop chasing inconsistent spreadsheets. Faster decision-making from clean, repeatable data; fewer human errors; and predictable, auditable data feeds that stakeholders can trust. 𝗕𝗮𝗰𝗸𝗲𝗻𝗱 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁 : I design and implement backend services and APIs that make automation and data accessible, secure, and scalable. I focus on clean REST endpoints, reliable database integrations (Postgres, MongoDB, Supabase), authentication, and deployment-ready code that can be containerized and monitored. Internal tools and automations become stable building blocks rather than one-off scripts, reducing downtime and technical debt. Your automation outputs become usable products—dashboards, integrations, or services—so other teams can consume data and functionality without engineering friction. 𝗔𝗜 𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻, 𝗥𝗔𝗚 𝗦𝘆𝘀𝘁𝗲𝗺𝘀 & 𝗣𝗿𝗼𝗺𝗽𝘁 𝗘𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴 : I integrate AI thoughtfully—using retrieval-augmented generation, prompt engineering, and workflow orchestration—to automate customer interactions, summarize data, and enrich decision workflows. I focus on safe, testable AI behaviors and on connecting AI outputs to your existing CRMs and databases. Faster, more personalized customer responses, automated knowledge retrieval, and reduced manual workload for repetitive communication tasks. Improved conversion and response times, consistent messaging, and AI that augments human teams rather than replacing them. 𝗗𝗮𝘁𝗮 𝗦𝗰𝗶𝗲𝗻𝗰𝗲 & 𝗔𝗻𝗮𝗹𝘆𝘁𝗶𝗰𝘀 : I apply practical data-cleaning, transformation, and basic modeling to turn collected data into insights. This includes ETL pipelines, exploratory analysis, and preparing datasets for visualization or downstream ML work. I prioritize explainable outputs and reproducible notebooks so results are transparent. Decisions are based on reliable, well-prepared data rather than gut feeling; trends and anomalies are surfaced earlier. Better forecasting, targeted actions from clean metrics, and a foundation for more advanced analytics or ML when you’re ready. 𝗙𝗿𝗼𝗻𝘁𝗲𝗻𝗱 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁 (𝗲𝗮𝗿𝗹𝘆-𝘀𝘁𝗮𝗴𝗲 / 𝗴𝗿𝗼𝘄𝗶𝗻𝗴) : I create simple, user-friendly frontends and dashboards that turn raw data into actionable views. My work emphasizes clarity: intuitive layouts, clear status indicators, and lightweight interfaces that let non-technical users explore results and trigger workflows. Stakeholders actually use the systems you build because the UI makes insights accessible. Faster adoption across teams, reduced support overhead, and clearer communication between technical and business users. I work with empathy and clarity: I translate technical choices into business outcomes, document handovers so teams can run systems independently, and communicate progress in plain language.
