JINSEOK SEOK — Software, Cloud & Automation

I am a software and DX engineer based in Japan. My engineering work bridges business operations and engineering: translating operational requirements into maintainable software, cloud systems, and developer automation that remain robust long after initial release.

Repository Lifecycle & CI/CD Governance Framework

An engineering initiative designed to make repository conventions, lifecycle management, and CI/CD governance explicit, reviewable, and automated.

• Soku-Convention-Boilerplate [Public]
  • Role & Architecture: Public convention entry point owning the lifecycle, manifest schema, managed-file ownership model, and generic provider boundary.
  • Tech Stack: TypeScript GitHub Actions Shell
• ci-cd-control-plane [Private · Selected details]
  • Role & Architecture: Central governance repository defining versioned pipeline contracts and declarative CI/CD provider boundaries.
  • Tech Stack: Go Cloud Architecture Declarative Pipelines

Desktop Media Packaging & Processing Tool

• Objective: Privacy-first, local-first media packaging without cloud uploads.
• Engineering Highlights: Secure local processing via Electron desktop wrapper with native FFmpeg streaming pipelines.
• Tech Stack: TypeScript React Electron FFmpeg

Declarative Architecture Modeling & Load System

• Objective: Declarative architecture visualization and simulated load-scenario verification.
• Engineering Highlights: Parses declarative YAML system models into visual topologies with simulated throughput verification.
• Tech Stack: Go React YAML

Automated Business Intelligence & Reporting Pipeline

• Objective: Automated operational data aggregation and multi-source reporting.
• Engineering Highlights: High-reliability batch data transformation, sheet synchronization, and reporting automation for business operations.
• Tech Stack: JavaScript Google Apps Script Google Sheets

Multilingual Cloud Portfolio Platform Prototype

• Objective: Type-safe multilingual portfolio platform with decoupled cloud backend.
• Engineering Highlights: Type-safe multilingual rendering, executable validation, and serverless integration.
• Tech Stack: Angular Go GCP

TypeScript Go Python JavaScript

• Practical & Professional Experience: Business workflow automation, cloud systems (Google Cloud, Google Workspace / Apps Script), operational software.
• Project Engineering: Web and desktop applications (React, Angular, Electron), declarative data modeling, media processing pipelines.
• Current Engineering Focus: Repository conventions, CI/CD governance, lifecycle tooling (Soku ecosystem).
• Languages used across work and projects: TypeScript, Go, Python, JavaScript.

Engineering quality is defined by predictable delivery, testable code, and transparent collaboration:

• Issue-first: Every task begins with clear intent, scope definition, and explicit acceptance criteria before implementation.
• Contract-first: Interfaces, API schemas, and data structures are formally defined to ensure decoupled, testable components.
• Verification-centered: Code changes are backed by automated tests, type validation, and concrete execution evidence.
• Explicit approval: Production releases, schema migrations, and security-sensitive configurations require deliberate human sign-off.

AI-Assisted Development: AI-assisted workflows adhere to the same review, linting, and testing standards as human-authored code.

• Live Status & Roadmap: Repository Operations · GitHub Project #2 is the source of truth for current status and priorities.
