Turning finance requirements into controlled, testable ERP delivery.
SAP Functional Consultant at Accenture, focused on S/4HANA FI-Tax. Four production cloud ERP go-lives sit behind that role — from requirements and configuration through UAT, cutover and adoption. I connect each business rule to its posting, table, reconciliation control and test evidence.
This portfolio is organised as a consultant evidence trail: the business problem, the functional decision, the system behaviour, the test proof and the measured outcome. Choose a lens and the site will take you to the most relevant evidence first.
Start with outcomes, then follow the transition from engineering discipline to ERP ownership and SAP FI/CO specialization.
Move from configuration to document posting, Universal Journal evidence, reconciliation and statutory output using sample data and clearly labelled assumptions.
The evidence is organised around scope, decisions, controls, testing, cutover and adoption — with delivered work kept distinct from proposed SAP design.

View SAP FI Tax scope →Tax is a chain, not a single program. Set-up decides what an invoice posts; postings feed the daily and month-end adjustment programs; one reporting engine turns them into certificates, attachments and e-filing files; the returns are due on fixed dates. Play a thread to follow one document end to end, or click any box to see what feeds it, what it feeds — and what breaks if it fails. Object codes are neutral (anonymized), the same as in the FI-Tax Knowledge Lab.
Change a number, press play, and watch the documents, the postings and the ledger move. Nothing here is a client system — standard SAP S/4HANA behaviour and Thai tax rules with sample amounts.
Animated document flow for four processes — Procure-to-Pay, Order-to-Cash, Thai withholding tax at payment, and a foreign service with PND54 and VAT self-assessment. Each step shows the T-code, the tables written and the debit/credit posting, while a T-account ledger fills up and clears.
Thai withholding tax and VAT on a payment: pick who you pay and for what, and see the WHT rate, the form (PND3 / PND53 / PND54), the 50 Tawi certificate, the cash that leaves the bank and the posting — including gross-up when the payer bears the tax.
Book a USD invoice at one rate, settle it at another and watch the realized exchange gain or loss appear — or let the market wander for 30 days and see it tick.
One payment, several profit centers: document splitting creates one WHT line per profit center, and a tax report needs one row per line with the base prorated so the totals still tie to what was filed.

Configured material masters, vendor data, and 2-level approval workflow on XeerSoft. Applied Poisson Distribution and Modified EOQ statistical models to solve chronic XS/XXL uniform stockouts and textbook write-off.
Attended 48 weekly Executive Sessions over 12 months. Extracted multi-tier pricing logic from live family advisory sessions and translated into structured FD with 3 core pricing variables and AR billing structure.
Detected critical bulk-assignment defect on first test cycle. Led 5 iterative UAT build cycles, managing 60 defects with structured reproduction steps to zero critical post-launch incidents across 50+ members.
Designed AR billing for Newton's STEM programme across seven subjects. Configured collection tracking, cost allocation, and per-subject P&L. Go-Live June 2026 — collection recovered to 95.0% via post-go-live dunning.
A tech-consultant exercise: each delivered XeerSoft system above, re-scoped as a proposed SAP design — business flow, technical/configuration design, a sub-unit test plan (10-step manual criteria), a development pipeline, team shape, and effort estimate.
Every go-live carried the full analyst trail behind it — FD, Use Case & User Story — plus GL account determination and master-data setup. This is real delivery on XeerSoft Cloud ERP; the ≈ SAP tags mark where each capability maps, not SAP project experience.
Newton Sixth Form Boarding School (under Learn Balance Group) is where these XeerSoft ERP projects came to life: a 200-staff, 3-branch organisation running integrated Procurement, Finance, CRM, and HR modules on a single cloud ERP platform.
As the sole on-site Implementation Consultant, I'm the bridge between business operations and the remote XeerSoft development team, gathering requirements in walkthroughs, authoring FDs, configuring modules, leading UAT cycles, and supporting daily users from accounting to admissions.
Projects on XeerSoft followed a hybrid model: Waterfall for upfront discovery and FD authoring, then iterative UAT cycles with weekly Dev builds. Each project averaged 5 build cycles before Go-Live.
Dev team delivered weekly builds. I tested 1–3 days per build (depending on complexity), met 2× per week for review and defect triage, functionally identical to Agile Sprint cadence with shorter cycles.
Every project starts with a written FD before code. ERDs map data relationships. UAT test cases trace back to FD requirements. No code is built without a signed-off spec.
Example board structure from CRM Loyalty UAT Cycle 2: 60 defects tracked across 5 build cycles to zero critical post-launch incidents.
Mechanical Engineering from Chulalongkorn University (Class Honors, GPAX 3.40) who crossed into ERP consulting, bringing analytical rigour from engineering into business process design and system implementation.
From 2023 to 2026, I delivered four production go-lives at Learn Balance Group on XeerSoft Cloud ERP. As implementation consultant and embedded Business Analyst, I carried requirements through configuration, master data, functional specifications, integration testing, UAT, cutover and hypercare — serving about 200 users across three branches and five integrated modules.
Prior hands-on exposure to SAP in a live automotive manufacturing environment at Mitsubishi Motors Thailand, where I operated SAP as an end-user for procurement and asset management of my FPDU Assist Device engineering project, which won the Best Achievement Award from the full intern cohort.
My current chapter is SAP Functional Consulting (FI/CO) at Accenture, contributing to an energy-sector SAP S/4HANA programme. The public portfolio deliberately limits client detail; it demonstrates my functional method through anonymized testing evidence, standard-SAP references and clearly labelled design exercises. In parallel, I am building depth in BIZBOK / TOGAF capability mapping, value streams and operating-model design, and preparing along the S/4HANA FI/CO certification paths.
Before my XeerSoft ERP work, I led an engineering project on the PHEV manual line at MMTh Factory #1, where I designed an ergonomic assist device using SQCDE evaluation across 8 design alternatives, managed the full SAP procurement workflow (MSR → e-AR → PR → PO → Asset deployment), and conducted FMEA risk reduction. Selected from the full intern cohort for the Best Achievement Award. This is where my hands-on SAP end-user experience originated.
Built in my final year, after the Mitsubishi internship in year three, these capstone engineering projects are where the technical discipline behind my consulting took shape. The structured testing, iterative refinement, and acceptance-criteria design I practised here is exactly what powers my UAT and BA work today.
Implemented a complete Deep Deterministic Policy Gradient (DDPG) agent in Python 3 + TensorFlow 2.x, trained over 5,000 episodes in the CARLA Simulator. Two tasks: (1) smooth steering with path-following and (2) adaptive cruise control with 2-second safe-following distance. Designed 7-dim and 4-dim state spaces, custom reward functions with jerk-penalty for smoothness, and modular 5-file codebase.
I led a 5-person team for MUVMI (electric tuk-tuk ride-sharing) across two tracks. On the software / control side I co-owned a new regenerative-brake system: an analog angular-position sensor and speed-banded regen logic, tested live on the vehicle at I'm Park, recovering up to +220% braking energy. On the hardware side I also worked hands-on with the team on the driver-ergonomics build (brake lever, rest pedal, sensor mount) and integrated it into the combined deliverable, though my teammates led that design. As team lead I owned the weekly submission and consolidated all Functional Specs for MUVMI, working directly with the company's CEO and senior engineers, all for a 660 ฿ bill of materials. Voted Top 3 of 16+ Mechanical Engineering Design projects across all groups (cohort 101).
Open to SAP FI/CO and ERP implementation / business-analysis roles in Bangkok. I bring four delivered ERP go-lives, current enterprise SAP functional experience, and an evidence-first approach to design, testing, controls and cutover.
