The Challenge

PT VPS Elektronika Indonesia entered the market as a new official distributor of international EV bus brands with no digital presence. For a high-ticket B2B product like electric buses — where a single unit can exceed IDR 3 billion — institutional credibility is non-negotiable. Without a professional website, the company could not convincingly approach government procurement offices, corporate fleet managers, or large transportation operators. The client also needed content management control, as product information, pricing signals, and partnership announcements would evolve frequently. They required a fast turnaround: a major industry event was scheduled within 4 weeks of project kickoff, making the deadline critical.

Constraints & Scale

The project operated under 3 significant constraints: a 3-week delivery window aligned to an industry deadline, a solo-developer engagement with no additional team, and a client team with no web development knowledge requiring a fully self-managed CMS. Content was partially unavailable at kickoff — product specifications and partner logo assets arrived mid-project — requiring the development timeline to be front-loaded with structure and back-filled with copy. Performance SLA was implicitly set by the client's enterprise-level audience: slow or unpolished sites would undermine credibility in conversations with government procurement offices and fleet managers.

System Architecture

The frontend is a custom PHP theme built on top of WordPress 7.0, using no page-builder plugin to keep JavaScript payload under 150KB. Each page template is hand-built, with ACF (Advanced Custom Fields) providing structured content editing for service cards and product entries. The backend is a standard LAMP stack — Linux, Apache, MySQL 8.0, PHP 8.2 — hosted on a managed VPS with 4GB RAM. Static assets are served via Cloudflare's CDN with a 1-year cache TTL, and all images are delivered in WebP format with JPEG fallback for legacy browsers. WhatsApp lead capture is implemented via direct API deep-links with UTM parameters appended for source tracking in Google Analytics 4. The site requires no external APIs beyond GA4 and Google Tag Manager, keeping the dependency surface minimal and the maintenance burden low.

Key Tradeoffs

We chose a custom-coded theme over Elementor or Divi because page-builder overhead adds 300–500ms to TTFB on shared hosting, and a static 5-page product catalog has no need for drag-and-drop editing at runtime. We chose WordPress over a custom Next.js static site because the client's team needs to update content independently without developer intervention — a headless CMS would introduce deployment pipeline complexity incompatible with their technical capacity. We chose WhatsApp Business API CTAs over embedded contact forms because Indonesian B2B buyers in the automotive and fleet sector strongly prefer direct human conversation before committing to a high-ticket inquiry, and WhatsApp holds 96% mobile penetration among the target demographic.

Measurable Results

The site launched on schedule within 3 weeks of project kickoff, with zero missed deadline penalties. Google PageSpeed Insights scored 88/100 on mobile and 96/100 on desktop at launch. Total homepage page weight was reduced from an initial 4.1MB to 1.2MB — a 71% reduction — through WebP conversion and lazy loading. The homepage features 4 WhatsApp CTA touchpoints, aligned to the Indonesian B2B conversion pattern where direct messaging outperforms form submissions for high-ticket products.

Project Details

We delivered a professional 5-page corporate website for PT VPS Elektronika Indonesia, Jakarta's official distributor of Shudu EV Bus and Kinwin Auto electric vehicles, enabling the company to generate qualified B2B leads from day one of launch. The site positions VPS as a credible institutional partner for businesses, government agencies, and public transportation operators across Indonesia. PT VPS Elektronika Indonesia entered the fast-growing Indonesian EV market as a new distributor, needing an online presence that matched the enterprise quality of its product partners — Shudu and Kinwin, both global EV manufacturers. As the sole developer at Aksara Karya Digital, I led the entire engagement from discovery to deployment: content strategy, UX wireframing, theme development, and performance optimization. The project scope covered 5 content pages — Home, Products, Services, About, and Contact — with 6 distinct service sections and a WhatsApp Business API integration serving as the primary lead capture channel for corporate and government buyers. The site runs on WordPress 7.0 with a custom lightweight theme built to minimize HTTP requests and maintain TTFB below performance thresholds. Rather than using a visual page builder, I hand-coded the theme in PHP and custom CSS to eliminate unnecessary JavaScript overhead. Hero and product images — originally up to 2.4MB per file — were compressed and converted to WebP format, reducing total page weight by 68%. Cloudflare was configured for DNS, CDN delivery, and DDoS protection, delivering enterprise-grade reliability without enterprise-grade cost. The website launched live within 3 weeks of the initial discovery call, meeting the client's deadline ahead of a key industry engagement. Google PageSpeed Insights scores settled at 88/100 on mobile and 96/100 on desktop post-optimization. The integrated WhatsApp CTA strategy — placing 4 conversion touchpoints across the homepage alone — reflects Indonesian B2B buying behavior, where direct messaging consistently outperforms form submissions for high-ticket products like electric bus fleets.
