Full Stack Developer
Ibrahim Haykal Alatas
I build enterprise CRM and manufacturing systems with Laravel and React — turning messy operational data and legacy ERP constraints into workflows people actually trust.
Systems that hold up
on the factory floor.
I turn operational bottlenecks — legacy ERPs, manual warehouse tracking, spreadsheet reporting — into software that stays reliable under real production load.
I'm a Full Stack Developer at PT Data Teknologi Terintegrasi, building VALAK CRM — an actuarial consulting platform on Laravel 12 and React 19. Before that I spent a year and a half inside Astra Otoparts Group digitalizing warehouses and maintenance workflows on top of a read-only Infor/Baan ERP: FIFO floor storage, rack visualization, Smart Andon, and a live Oracle-to-PostgreSQL migration with zero downtime.
Things I shipped.
Enterprise platforms, manufacturing tooling, and client products — most of them running in production right now.
VALAK CRM — Actuarial Consulting
Enterprise CRM for an actuarial consulting firm on Laravel 12, React 19, TypeScript, and MySQL. A 19-stage project board synced live over Pusher with optimistic drag-and-drop and rollback, 32 REST endpoints across 6 controllers, an Excel-driven configuration pipeline that rewrites cells in place while preserving multi-sheet structure, and role-based dashboards for 6 internal roles.
Real-Time Warehouse Inventory
FIFO floor-storage monitoring for Astra Otoparts Group covering 48 material blocks and 400+ weekly transactions, with QR gate in/out, digital block visualization, and supply scheduling — cutting material search cycle time by 76.10% (103.00 → 24.62 minutes), validated by time study.
Smart Andon Ticketing System
Stateful digital ticketing that maps physical manufacturing workflows. QR validation, lifecycle tracking, technician activity monitoring, and Mean Time To Repair (MTTR) visibility for production issue handling.
Mitsubishi Dealership Landing
Freelance corporate profile and lead-generation landing page for a Mitsubishi dealership. Interactive vehicle showcases using Swiper.js and direct WhatsApp routing to accelerate sales conversions.
SME Digital Platform
National 2nd place hackathon platform for MSMEs (Jun 2025). Integrated a WhatsApp chatbot to streamline user engagement, digital marketing, and automated customer workflows.
SIPS Android Archiving
Full-stack archiving system built from a comparative study at BBSPJIKFK (Ministry of Industry). Architected with comprehensive UML and powered by a RESTful API.
AI Defect Detection (Fender Apron)
End-to-end visual inspection pipeline for automotive parts (Dec 2024). Custom dataset annotation via Roboflow, YOLOv8 training, and a live real-time inference app on Streamlit and WebRTC for automated quality control.
Wedding Organizer Platform
Web platform managing venue operations, dynamic package pricing, and customer inquiries. Streamlines vendor–client communication and booking logistics.
Q-Tin Dashboard UI
Responsive UI components for a smart dashboard using DaisyUI and Flowbite, built as part of a bilingual corporate profile platform with cross-device consistency.
Education Chat Bot
AI-powered learning assistant using deep learning NLP for intelligent, context-aware responses to student queries.
E-Brochure — Indomobil
Interactive digital automotive catalog with dynamic vehicle showcases, customizable color selections, and direct WhatsApp integration for sales lead generation.
Portfolio Website
This site. Personal portfolio built on Next.js and TypeScript with a hand-tuned GSAP scroll system, scroll-driven transitions, and a fully responsive layout.
Cargo Invoice System
Admin system for Herona Express optimizing logistics transactions and invoice generation, with master data management for regional shipment tracking.
Where the work happened.
Production systems in manufacturing, consulting, and client delivery — measured by what changed on the floor, not by feature count.
Full Stack Developer
Developing VALAK CRM, an actuarial consulting platform on Laravel 12, React 19, TypeScript, and MySQL — spanning authentication, master data, calculation, and reporting for 6 internal roles.
Built a 19-stage project board with Pusher real-time sync and optimistic drag-and-drop with rollback, using in-flight move reconciliation to prevent stale-state overwrites under rapid updates.
Delivered 32 REST endpoints across 6 controllers on a repository–service–handler structure, and resolved cross-layer defects in role-based board access.
Engineered an Excel-driven configuration pipeline: client-side parsing, header-driven editable previews, and in-place cell rewriting that preserves multi-sheet structure — relayed to a legacy calculation engine via machine-to-machine auth.
Built role-based dashboards and todo workflows for all 6 roles with a shared typed chart library and Leaflet maps, plus AI summary insights scoped per project and aware of document versions.
Full Stack Developer / System Engineer Intern
Developed a FIFO floor-storage warehouse monitoring system covering 48 material blocks and 400+ weekly transactions with QR gate in/out, digital block visualization, and supply scheduling — cutting material search cycle time by 76.10% (103.00 → 24.62 minutes, validated by time study).
Built a finished-goods visualization system for Giant Rack Plant 3, mapping 80+ rack columns across multi-layer, top, and side U-shape layouts with customer filtering, barcode scanning, and shipment status tracking.
