About
Where ExperienceMeets Engineering
I bridge real industry experience with technology to design and build digital systems that are scalable, reliable, and aligned with business objectives.
Product Thinking
Workflows are framed around user needs, business context, and measurable outcomes.
Enterprise Architecture
Systems are structured for reliability, governance, and clear operational boundaries.
Software Engineering
Implementation is grounded in clean modules, validation, data models, and maintainable code.
Selected Work
Real Products. Real Impact.
A selection of enterprise products I have architected and engineered to solve real operational challenges.
01
COALISTIX Enterprise
FlagshipA full-stack enterprise platform for coal trading and logistics operations, connecting transactions, contracts, shipments, cargo tracking, stockpile activity, and dispatch workflows.
Challenge
Coal operations involve many connected records, handoffs, approvals, logistics assets, and status changes. The system needs enough structure to keep commercial, operational, and audit context aligned without hiding the work inside spreadsheets or disconnected tools.
Solution
COALISTIX Enterprise implements domain modules for the core operating flow: master data, transactions, contracts, shipments, cargo tracking, stockpile management, dispatch, dashboard reporting, and authenticated access.
My Role
Product & Engineering, with emphasis on solution architecture, domain modeling, and full-stack implementation.
Engineering Approach
- Separated backend and frontend applications in a workspace structure, with NestJS serving API modules and a Vite React frontend organizing product areas by feature.
- Modeled the operating domain in PostgreSQL through Prisma, including tenants, users, roles, permissions, audit logs, counterparties, contracts, shipments, cargo events, stockpile records, and dispatch entities.
- Applied guarded API boundaries with authentication and permission checks around operational controllers, keeping access rules close to the domain endpoints they protect.
- Kept UI implementation aligned to product workflows through feature folders for transactions, contracts, shipments, dashboard, master data, and authentication.
Engineering Evidence
- Backend modules exist for authentication, dashboard, transactions, contracts, shipments, cargo tracking, stockpile management, and dispatch.
- Prisma schema contains role, permission, session, audit, transaction, contract, shipment, cargo, stockpile, dispatch, and marine/logistics master-data models.
- Controllers declare domain permissions such as transaction, cargo, stockpile, port, vessel, barge, tugboat, and coal specification access.
- Frontend feature areas include protected authentication flows, transaction lifecycle screens, contract detail/edit flows, shipment scheduling, dashboard views, and master-data modules.
- Repository includes tests around controller permissions, lifecycle behavior, child aggregates, cargo tracking, stockpile, and master data.
02
COALISTIX Website
A public-facing digital experience for the COALISTIX product, structured around industry context, platform positioning, solutions, resources, and contact conversion.
Challenge
The website needed to communicate an enterprise operating platform clearly while supporting multilingual content, contact intent, and product context without becoming an overloaded brochure.
Solution
The implementation uses a structured Next.js app with localized public routes, reusable homepage and site components, validated contact handling, and supporting dashboard/assistant foundations.
My Role
Product & Engineering, focused on digital experience architecture and frontend implementation.
Engineering Approach
- Built public routes for about, contact, industries, platform, resources, and solutions with locale-aware routing.
- Separated content, site navigation, homepage sections, contact handling, AI assistant components, and dashboard support code into focused modules.
- Used schema validation for contact requests and generated SEO surfaces such as robots and sitemap from application routing utilities.
Engineering Evidence
- Next.js app includes localized public pages and next-intl routing.
- Contact API and contact form code use a Zod schema with explicit field limits and validation.
- Homepage, site navigation, AI assistant, conversion, and dashboard components are organized into separate source areas.
- Sitemap and robots entries are generated from SEO utilities rather than hand-coded page lists.
03
COALISTIX Enterprise Admin Dashboard
An administrative dashboard for COALISTIX operating oversight, covering website analytics, conversion analytics, AI operations, security, audit, and administration views.
Challenge
Administrative users need oversight across operational, security, audit, analytics, and AI-support areas without mixing every concern into one undifferentiated dashboard.
Solution
The admin app separates dashboard domains into protected routes and focused component groups, with role-to-domain authorization handled at the server boundary.
My Role
Product & Engineering, focused on dashboard information architecture and administration workflow implementation.
Engineering Approach
- Implemented as a dedicated Next.js admin app inside the COALISTIX website monorepo.
- Organized dashboard areas by domain: home, website analytics, conversion analytics, AI operations, security, audit, and administration.
- Enforced server-side dashboard authorization using approved administrative roles and explicit domain permission mappings.
Engineering Evidence
- Admin routes exist for dashboard home, website analytics, conversion analytics, AI operations, security, audit, and administration.
- Navigation config maps each dashboard domain to stable routes and localized labels.
- Authorization code defines approved administrative roles and default-deny domain permission checks.
- Component groups exist for administration, audit, security, AI operations, website analytics, and conversion analytics.
04
Employee Attendance Management
A focused attendance management app for employee check-in workflows, attendance history, admin review, employee records, and leave handling.
Challenge
Attendance tools need reliable daily records, role-appropriate access, and simple admin visibility without inflating the workflow beyond the team operations it serves.
Solution
The app provides employee and admin surfaces with authentication, attendance actions, attendance history, employee management, leave handling, and a PostgreSQL-backed data model.
My Role
Full-Stack Engineering, focused on application flow, authorization boundaries, and attendance business rules.
Engineering Approach
- Implemented with Next.js App Router, Prisma, PostgreSQL, NextAuth, and server-side role checks.
- Separated admin and employee routes so review, mutation, and employee self-service flows remain clear.
- Centralized attendance date/time rules around the Asia/Jakarta business calendar and workday policy.
Engineering Evidence
- Prisma schema defines users, employees, attendance records, roles, attendance statuses, and unique daily attendance per employee.
- Routes exist for admin attendance, leave, employees, employee attendance actions, history, login, and auth API handling.
- Authorization helpers enforce Admin, Employee, and Demo access rules, including demo mutation restrictions.
- Tests cover attendance time rules, attendance history, admin attendance, leave handling, authorization, demo account behavior, and synthetic datasets.
