Software Development
Web business systems, admin panels, and data-facing pages — from requirements clarification and scope splitting through core development and deployment.

From requirements and scope to development, deployment, and delivery.
For teams and individuals who need Web business systems, GIS/WebGIS, 3D visualization, or data automation — with clear phase boundaries and engineering handover.
Problems I often help with
Grouped by project type — each maps to a service direction below.
A Web business system or admin panel where the first-release scope is still unclear.
View serviceMaps, spatial data, and business workflows need a maintainable GIS / WebGIS approach — not a simple embedded map.
View serviceLarge 3D scenes, model interaction, or 3D Tiles loading performance is blocking the project.
View serviceA legacy system needs takeover, extension, or second-phase development with unclear code and docs.

GIS / WebGIS Development
GIS and WebGIS systems, map business modules, GIS customization, and spatial data work — OpenLayers, PostGIS, GeoServer, WMS/WFS/TMS, routing, offline GIS, and large spatial datasets.
View service3D Visualization
3D scenes, model interaction, trajectory animation, and 2D/3D linked experiences — grounded in Cesium, Three.js, and 3D Tiles practice.
View serviceSystem Modernization & Ongoing Development
Take over existing front-end or 3D systems — triage, extension, interaction fixes, and iteration within agreed boundaries; no blind promise on every stack without assessment.

Real project problems and delivery paths — metrics only where they are established facts.
Open requirements to system shape
On a fiber inspection GIS project, started from open questions — how inspection and check-in work on maps — and helped shape Web + mobile flows, GIS data/services/APIs, and phased tasks with PM.
Large spatial data at scale
In the same GIS project, refactored 20M+ vector features into a PostGIS / GeoServer / WMS service chain for map display and click query.
20M+ spatial features
Large-area 3D resource control
Organized Hong Kong Island–scale 3D Tiles by spatial regions with camera frustum load/unload to control memory and render pressure.
2D / 3D linked editing
Built 2D editor and full 3D preview linkage with UV/texture mapping for exhibition-style models — collaborative project with clear module ownership.
Self-built full-stack product
Family Growth Bank — independent business rules, Vue + Spring Boot stack, PostgreSQL, private deployment, and iteration from real family use.
Selected case studies
End-to-end delivery examples across GIS, 3D, and full-stack product work.
Full project case
Fiber network inspection GIS
Web + mobile GIS for inspection check-in, device capture, and route management — including large spatial data and map service modules.

2D / 3D linked editor
Collaborative exhibition editor: I owned the 2D editor and all 3D visualization and interaction — UV/texture mapping and model node access.

Family Growth Bank
A full self-built product from real family task and points incentives — business rules, front end, back end, database, test acceptance, and private deployment iteration.

About me
Software engineer with 8+ years of experience across Web applications, GIS / WebGIS, 3D visualization, spatial data, and engineering automation. I have worked as a WebGIS engineer, GIS R&D lead / core engineer, and GIS architect. Since September 2025, I have been working independently, focusing on turning open-ended requirements into workable systems and carrying them through development, deployment, and delivery.

For software project opportunities — background, technical constraints, delivery approach, and collaboration model.
Good starting points
- A Web or GIS system idea where the first release scope and technical path are still unclear
- Map, 3D, or spatial data performance or architecture bottlenecks on an existing build
- Taking over a legacy system, extending features, or continuing second-phase development
- Engineering data collection, cleaning, or QA workflows with scripts or tooling
- A fixed milestone where you need an independent engineer to deliver or co-deliver
Helpful context before we talk
- Project background, users, and current pain points
- Existing pages, prototypes, sample data, or reference systems
- Stack preferences, deployment environment, or team setup
- First-release scope and timeline / budget expectations
- Confidentiality, offline deployment, or compliance constraints
