Turn agricultural market data into actionable insights.
I build custom data and analytics solutions for agriculture businesses, including market price comparison, competitor monitoring, supplier research, and product intelligence.
I can collect publicly available data from relevant sources and turn it into a clean dashboard where you can compare products, suppliers, prices, countries, and market trends in one place.
The system can be built for different agricultural categories, from machinery and equipment to seeds, crops, fertilizers, and other products.
What I can build:
Agricultural web scraping & data collection
Product and price comparison
Competitor and supplier monitoring
Market trend analysis
Custom analytics dashboards
Data filtering, categorization & normalization
AI-powered insights and summaries
API integration and automated data workflows
Every project is customized around the data you need and the way your business works.
Have a specific agricultural data problem? Feel free to contact me and let's discuss what can be built.

Built Around Your Requirements
Every website is different. Instead of using a one-size-fits-all scraper, I build the extraction workflow around the website and data you actually need.
You provide the target website and the information you want to collect. I'll analyze the available data structure, determine the appropriate extraction approach, and build the workflow accordingly.
Have a website you need data from?
Send me the URL and tell me what information you need. I'll review the requirements and determine the best approach.

LUMORA Aesthetic Clinic: Booking Website with WhatsApp Integration and Owner Dashboard
I designed and built a full business website for LUMORA Aesthetic Clinic, a skincare clinic in Jakarta. It's not just an informational site, it's a working booking system that connects directly to WhatsApp, so the client doesn't need to manually go back and forth to get customers scheduled.
What it does:
One-click WhatsApp booking. Every service, doctor, and CTA button generates a pre-filled WhatsApp message with the specific service and doctor already included. Leads land in the owner's chat ready to confirm, not a cold "hi" message.
Dynamic service catalog. 7 treatment types with pricing, each independently bookable.
Doctor scheduling display. Per-doctor specialization, working days, and hours, so customers can pick based on availability before messaging.
Live weekly operating schedule. Shows real-time slot status (full, busy, limited) per day.
Owner dashboard with login. The clinic owner can update schedules and availability themselves through a private admin panel, without needing me to edit the site every time something changes.
Social proof section. Client testimonials and a clinic photo gallery to build trust before booking.
Location integration. Embedded map and address for walk-in customers.
Why this matters for the business:
This isn't a static portfolio-style site. It's built to actually convert visitors into booked appointments, and it keeps running without ongoing developer involvement, since the owner can manage day-to-day changes (schedules, availability) themselves.
Stack: React, Vite, Next.js, Tailwind CSS, a custom backend for the owner dashboard and login, deployed on production infrastructure with SEO-ready structure (fast load, mobile-first, clean metadata).

EXAPI - Public Media Processing API with Sub-100ms Global Response Times
I built and maintain EXAPI, a public REST API that lets developers download and process media from major platforms through a single, unified endpoint, with live, interactive documentation so anyone can test it directly from the docs, no separate playground needed.
Platforms supported:
Instagram, TikTok, Smule, Spotify, X (Twitter), Facebook, Threads, and CocoFun.
What makes it production-grade:
Lightning fast - sub-100ms response times globally, achieved through an API-based architecture I re-engineered from an earlier, less stable headless-browser automation approach.
Bank-grade security - enterprise-level protection on every call, including Bearer token authentication.
Infinite scale - built to handle high-volume traffic without breaking, backed by a Redis-based message queue and dispatch system that prevents message/data loss under load.
Under the hood: Python, FastAPI/Flask, PostgreSQL, Redis, deployed on production Linux VPS infrastructure with Nginx, Docker, and CI/CD via GitHub Actions, monitored and maintained by me directly for uptime and incident response.
Proof it works at scale: EXAPI is the same infrastructure powering three of my self-funded consumer products (TikTok, Smule, and Starmaker downloaders), serving real user traffic, not just a demo API.
