SHINSAN / 神算 — STRATEGY × DATA × AI

From hands-on experience
to better systems,
powered by AI and digital.

Drawing on experience across sales, business operations and corporate functions, I use AI and digital tools to improve workflows and build systems that work in practice.

ABOUT / PROFILE

PROFESSIONAL PROFILE | ZENFUKU

Starting on the frontline,
then learning to design the system.

I began my career in customer-facing and frontline operations, then expanded into B2B sales, sales promotion, branch and organisational management, corporate functions and overseas sales. Today, I connect that practical experience with strategy, data, AI and digital tools to create improvements and systems that work in real operations.

EXPERIENCE / BREADTH

From understanding customers
to understanding the business and organisation.

Rather than staying within one speciality, I have worked across B2C and B2B, frontline operations, sales, management, corporate functions and overseas business. That breadth now forms the foundation of how I approach process improvement.

FRONTLINE / BtoC

Customer-facing operations & sales

I started in stores and frontline customer service, gaining experience not only in sales but also staffing, operational quality and continuous improvement.

SALES & PROMOTION / BtoB

Corporate sales & sales promotion

I handled proposals for companies and public-sector clients, promotional campaigns, events and field operations, working across planning, proposal, execution and improvement.

MANAGEMENT

Branch & organisational management

My responsibilities expanded to P/L, KPIs, recruitment, evaluation, staffing and organisational management, giving me a broader view beyond individual projects.

CORPORATE / OVERSEAS

Corporate functions & overseas sales

I worked across accounting, HR, general affairs and recruitment, as well as overseas sales in manufacturing, including costing, quotations, production processes and coordination with overseas operations.

NOW

Business Operations × AI / DX

I now combine that practical background with generative AI, data and web implementation, selecting technology based on the work itself and connecting improvement ideas with working prototypes and implementation.

APPROACH

Understand the work.
Improve the system.

I do not start with a tool. I start with the current situation and the desired outcome, then treat problem definition, improvement design, implementation and validation as one continuous process.

01

Understand

Clarify the work, context and objectiveASSESS
02

Define

Make bottlenecks and information visibleDEFINE
03

Design

Redesign roles, processes and actionsDESIGN
04

Implement

Use AI and digital tools where they add valueIMPLEMENT

EXPERTISE

Start with the business problem.
Then choose the right means.

AI adoption is not the goal in itself. I look across work, people, data and systems to identify practical ways to improve how the business operates.

01

Process Mapping

Clarify workflows, roles and bottlenecks so the real improvement opportunities become visible.

02

Process Improvement・BPR

Reduce duplication, hand-offs and dependence on individuals by redesigning processes and responsibilities.

03

AI & Digital Enablement

Combine generative AI, existing SaaS and familiar tools such as Excel to create solutions suited to actual operations.

04

Data & Validation

Build a cycle of data collection, hypothesis, action and validation so improvement is not driven by intuition alone.

05

Sales, Organisation & Corporate Operations

Apply hands-on experience in sales, recruitment, management, accounting and HR to problems that cross functional boundaries.

06

Prototyping & Implementation

Turn concepts into tangible materials, websites and workflows that can be reviewed, tested and improved.

SELECTED CASES

Different fields.
The same problem-solving discipline.

Long before generative AI, my work already centred on understanding the frontline, breaking problems down and changing the system behind them.

FEATURED CASE 01 / FLAGSHIP STORE OPERATIONS

Redesigning the system
so people join, grow and stay.

In a manufacturer’s flagship-store operation, continuous recruitment, development and retention had become a major operational issue. Rather than treating it simply as a shortage of applicants, I separated the problem into candidate pipeline, hiring quality and retention, then reviewed recruitment media, applicant handling, competitor conditions, training, onboarding, mentoring, evaluation and compensation as one connected system.

Recruitment cost~20% lower
Turnover rate~10% better
Build the pipelineOptimise candidate touchpoints and channels
Improve hiring qualityAlign selection, information and expectations
Build retentionRedesign development, evaluation and onboarding
DATA → HYPOTHESIS → ACTION → VALIDATION | Moving from intuition-led operations to a measurable improvement cycle.

What if the real shortage was not people, but clearly designed roles?

We reviewed a structure in which sales, recruitment, training and administration were concentrated in the same roles, and introduced a dedicated support function for project operations. The aim was to support performance through role design rather than individual effort alone.

CASE 02 / RESOURCE STRATEGY

Changing the talent supply strategy
to fit the objective and constraints.

Right people × Focus × Scale

I have adapted recruitment channels and candidate-pipeline strategies to different requirements, including quality standards, peak seasons and large-volume staffing.

CASE 03 / BUSINESS MANAGEMENT

Looking beyond the project
to the branch and organisation.

Project → Branch → Organisation

My scope expanded from individual project sales, profitability, staffing and quality to P/L, KPIs, recruitment and evaluation across multiple projects and organisational units.

TOOLS

Tools are not the objective.
They are how ideas become workable.

I use different tools to think, operate, measure and create depending on the problem. The goal is not to depend on a particular product, but to combine the right tools for the job.

SHINSAN DESIGN

Clarify the problem.
Make the solution visible.

I turn business and marketing objectives into tangible web, video and advertising outputs. Here are three areas selected from my current portfolio.

AI BRAND FILM / CURRENT

From shot design to a coherent AI-generated story.

Brand-film production combining shot planning, reference materials, generation, selection and Premiere editing, with human direction shaping the final result.

WEB / LIVE SITE

Turning a recruitment journey into a working website.

From recruiting landing pages to other live concepts, I structure content around the audience, objective and decision journey, then implement it as responsive web.

CREATIVE EXPERIMENTS

Testing how different creative approaches change the message.

Six themes developed as A/B creative pairs, designed to compare differences in messaging, emphasis and visual treatment rather than simply display isolated banners.

Let's work out
the next practical step.

The problem does not need to be fully defined yet. I can help organise the work, people and data involved, then use AI and digital tools where appropriate to turn that understanding into a practical next step.
