IT Manager Portfolio
IT leadership, cross-branch coordination, and practical digital products.
I'm Jesadakorn Kirtnu, a Phuket-based IT Manager at VIGNOLD. In my current role, I work closely between the Thailand and German branches to support IT operations, coordination, and business continuity. Separately, I build EPSX as a side project, which reflects my personal interest in creating clear and practical digital products.

working style
Business coordination, operational support, and practical digital product delivery.
Selected Side Project
EPSX side project spanning public analytics and internal operations.
EPSX is a separate side project where I shaped a clear product experience for two audiences at once: people exploring market analytics on the public platform and operators managing access, payments, notifications, and developer workflows behind the scenes.
Role
A personal side project where I handled the product-facing interface delivery across both surfaces, turning complex requirements into structured navigation, plan-aware states, and day-to-day operational tooling.
Scope
The work covered epsx.io and admin.epsx.io as one connected system, with emphasis on high-density information, permission-sensitive flows, and interfaces that stay legible under real operating pressure.
38
Public product states
Landing, pricing, analytics, portfolio, notifications, plans, and developer experiences.
46
Admin states
Operations, wallet access, plans, payments, notifications, and audit-heavy tooling.

Live product surfaces
A public user-facing platform and a separate admin operating environment.
What the work required
Designed and built interface patterns shared across the public product and the internal admin console.
Mapped gated states, wallet-related flows, analytics views, and developer-facing tooling into a coherent navigation system.
Focused on clarity for heavy operational tasks rather than decorative UI, especially across admin, notifications, and access management.
Live surfaces
The public platform and the admin console were designed to feel related, but each interface was tuned to its own job: one for product discovery and usage, the other for operational control.
Public Platform/38 states
epsx.io
A public-facing analytics platform built around plan-aware access, watchlist workflows, and data-heavy product navigation without losing readability.
Established a landing and pricing experience that explains the product clearly before users enter gated flows.
Structured rankings, filtering, search, and premium access states so dense information remains scannable.
Connected watchlists, portfolio tracking, and developer tooling inside a product shell that feels consistent end to end.
