Data Analytics & GenAI Engineering
Mochammad Reyhan Mauluddi
Data Analytics Specialist & GenAI Engineer
Transforming complex, high-volume datasets into strategic blueprints — and now extending that expertise into Retrieval-Augmented Generation applications that turn raw data into AI-powered insight.
About Me
Turning complex data into clear answers
In today's data-heavy world, everyone has information, but very few have clear answers. As a Data Analytics Specialist with over 6 years of experience, my career has been defined by a single mission: transforming complex, high-volume datasets into the strategic blueprints that drive business solutions. I specialize in the intersection of mathematical precision and commercial intuition.
Life Mission
To build impactful data solutions using the latest technology and analytics while growing my career globally.

Sport
Beyond the data, you'll find me out for a run or a ride.
Investment
Actively exploring investment opportunities in both physical assets and digital banking platforms.
Data Analytics and AI
Passionate about architecting end-to-end data solutions and diving deep into the world of Generative AI to build smarter, data-driven systems.

Things I've built
WiseSherpa — Gamified Job Hunter Advisor
An AI job-search copilot that reads job-alert emails (JobStreet, LinkedIn, Indeed) via Gmail API, filters them against a parsed CV down to the ~20 best matches a day, then scores each on fit (relevance, credibility, benefits) and acceptance odds, alongside multi-persona POV analysis from a Job Advisor, User Advisor, and HRD Advisor — in a gamified quest board.
Business Impact
Turns passive job-alert inboxes into a scored, actionable pipeline — so job hunters spend their time on the listings worth applying to, with an authority-level advisor perspective.
Advanced RAG with LangGraph — "RASA"
A LangGraph-orchestrated platform that combines structured (Pandas) and unstructured (vector) data, dynamically routing and synthesizing multi-source insights into one natural-language narrative.
Business Impact
Lets non-technical stakeholders ask natural-language questions and get both hard numbers and contextual explanation back — cutting the time between a business question and an answer from hours of analyst work to minutes.
BigQuery Text-to-SQL Agent
An AI agent that turns natural-language questions into transparent SQL against Google BigQuery, returning tabular results, chart recommendations, and a visualized LangGraph workflow trace.
Business Impact
Removes the SQL bottleneck between business teams and their data — anyone can query a BigQuery warehouse in their language, while the visible SQL and workflow trace keep results auditable and trustworthy.
Customer Churn & Analytics Dashboard
Interactive data application for descriptive, diagnostic, and predictive churn analysis, integrated directly with Google BigQuery and a RAG pipeline that lets users query both tabular data and PDF documents for actionable business insights.
Business Impact
Helps retention and marketing teams spot at-risk customers before they churn and pair the numbers with supporting documents in one place — turning a reactive retention process into a proactive one.
Retail Sales Performance Dashboard
An interactive Power BI dashboard built on a full star-schema data model, tracking retail sales, growth, and product performance.
Business Impact
Gives retail stakeholders a transparent, end-to-end view of the business — from raw source data and DAX logic through to store-level performance.
Ecommerce Sales & Revenue Dashboard
An interactive Looker Studio dashboard connected to Google Sheets, tracking ecommerce sales and revenue performance.
Business Impact
Gives ecommerce stakeholders a comprehensive, always-current view of sales and revenue — from a general overview down to per-store performance.
End-to-End Analytical Pipeline
Migrated legacy manual Excel workflows to automated R-based scripts, covering data cleaning, statistical modeling, and streamlined Power BI reporting.
Business Impact
Cut a multi-hour manual Excel reporting cycle to a repeatable programming cycle with scripts.
LLM-based Recommendation System
Master's thesis (Institut Teknologi Sepuluh Nopember) — a recommendation system built with LLMs and prompt engineering to evaluate the Top Brand Award as a business unit and enhance competitive value.
Business Impact
Top Brand Award as a business unit gets a strategy recommendation grounded in broad public opinion, helping it sharpen its competitive value.
VPS Data Infrastructure
Configured and managed an Ubuntu-based VPS to host Airflow webservers and schedulers for automated data engineering DAGs.
Business Impact
Keeps scheduled data pipelines running reliably and on time without paying for a fully managed service — so downstream dashboards and reports are never stale when leadership checks them.
Working Experience
Diverse industries, one core skill: turning data into decisions
6+ years turning data into decisions across five very different worlds — government integrity surveys, telecom operations, national market research, FMCG distribution, and now Generative AI. Along the way: 10M+ record government databases, multi-industry client surveys, regional sales data, and unstructured documents fed into RAG pipelines. Same core skill, applied wherever the data lives.
