FECT — AI customs & trade portal

FECT is the flagship product of Rudasoft (now Astra Technology) — an AI-integrated portal for cross-border trade that brings customs operations into one place for 500+ import-export enterprises. At its heart is an AI trade consultant that handles everything from HS-code and tariff lookups to rules-of-origin and legal questions, wrapped around six modules: Q&A, Origin, Inventory, Clearance, Track and Express.

FECT — AI customs & trade portal
The challenge

By August 2024 the FECT product worked — 500+ enterprise users — but its landing didn't. A generic page converted at just 3.2%, bounced 68% of visitors and held attention for 23 seconds. With a Series A raise and a Vietnam expansion ahead, the company needed a marketing portal that told the story and qualified leads — with a brand-new AI chatbot, FectQ, built in. The catch: four weeks, zero marketing / pricing / feature documentation, and a Korean board referencing a dozen unrelated sites with no settled direction — and no PM, BA, marketing or motion designer to lean on.

01UX Research & Strategy

Before any screen, I mapped how exporters actually move through customs — the documents, the hand-offs, the moments things break. In customs, one wrong HS code or a missing certificate stalls a shipment, so the research had to be precise.

  • Designed for multiple user flows — Seller, Buyer and Admin — plus a dedicated responsive experience for the Buyer.
  • Mapped the end-to-end journey across all six FECT modules (Q&A, Origin, Inventory, Clearance, Track, Express).
  • Ran usability sessions and behaviour tracking to locate friction — the document flow was the biggest drop-off.
  • Built an analytics framework of 15+ KPIs (funnels, cohort retention, feature adoption) so every decision was evidence-led.
  • Tore down 12 customs-software landing pages to learn what actually converts in the category.
  • Wrote the content-requirements doc the company didn't have — then got the CEO to supply expert customs copy via a translator.
  • Reframed a regulation-first product around the user's task, not the bureaucracy.
02UI & Visual Design

I designed a calm, information-dense interface that carries a lot without feeling heavy — plus the 'fect' brand (the iridescent cube) so a compliance product still reads modern and trustworthy.

  • High-fidelity UI for the Portal, Admin and Certificate-of-Origin / Clearance flows.
  • A restrained visual language: clear hierarchy, generous spacing, status-driven colour for a data-heavy domain.
  • Designed the 'fect' identity and applied it consistently across web and mobile.
  • Guided, step-by-step flows with in-context help that cut the support burden.
03Product Management

As product owner I set the roadmap by business impact and technical feasibility, and coordinated a 12-person cross-functional team across four core systems.

  • Owned the product lifecycle across 4 core systems generating $500K+ ARR.
  • Prioritised by revenue potential, retention and feasibility; tracked it all in Jira, Notion and Figma.
  • Led a design-system standardisation initiative across 3 product lines.
04Front-End Development

I vibe-coded the Portal from Figma into a live front-end myself — turning the tokenised design system into the running site at fect.vn.

  • Vibe-coded and shipped the FECT Portal front-end (fect.vn).
  • Translated design tokens into code components for one-to-one consistency.
  • Bridged design and engineering daily, closing the gap between intent and implementation.
  • Handed engineering comprehensive component specs, reference links and detailed motion specs — citing specific animation references — for a faithful build.
Approach
  1. 01

    Discover

    Shadowed how exporters actually file customs — interviews, support logs and behaviour data — to find exactly where shipments stall.

  2. 02

    Define

    Reframed six scattered modules into one coherent product and set the KPI framework that would judge every decision.

  3. 03

    Systemise

    Built the tokenised design system so the Portal, Admin and CO flows all spoke one visual language.

  4. 04

    Design & build

    Designed the high-fidelity flows, then vibe-coded the Portal front-end live at fect.vn.

Key decisions

Treat the board as users, too

The endless approval loop was really a research gap. I studied the Korean board's design culture and a dozen Korean sites, found the shared aesthetic (vibrant, dynamic, youthful) and designed toward it — turning subjective debate into alignment.

Two design systems, on purpose

The product design system didn't fit a vibrant marketing landing, so I spun up a second, simplified system for the landing — keeping product consistency while meeting the board's aesthetic, fast.

Skip hi-fi wireframes

With four weeks and no content, I prototyped straight on the design system instead of wireframing — running design and CEO-supplied content in parallel to hit the deadline.

One UI, switchable real / demo data

Missing real assets could have blocked the build. A switchable real/demo mode with an identical interface let the page ship now and swap in real content later.

Ship hero motion now, hire a specialist for v2

With no motion designer and a hard deadline, I spec'd the animations myself and agreed with the board to keep the hero motion as-is — while advocating to bring in a dedicated motion designer for the next release.

Outcome
  • Document completion rate 68% → 90%
  • Customer activation 12 days → 4 days; CSAT 7.2 → 8.9
  • Support tickets −40% (~$20K/yr saved) via in-app guidance
  • Design system cut development time ~30% and lifted UI consistency 6.2 → 8.8
  • $500K+ ARR across 4 core systems
Reflection

The biggest lesson wasn't visual — it was that stakeholders are users too. Researching the board's design culture turned an endless approval loop into alignment. And with no product, marketing or motion role in place, I had to stretch across all of them without dropping the thread — the breadth I think a modern product designer should have.
