Engineering Hobby Lab

Viktors Jesilevskis

Engineering leadership ideas, explored through hands-on builds

I use small, focused projects to test ideas from platform transformation, engineering governance, and enterprise architecture in working systems.

Platform Systems Engineering Analytics Delivery Governance AI-assisted Engineering

This is primarily a hobby project lab for personal learning and practice. Production work is explicitly identified where included.

Shared engineering baseline

Every project is built around Guidelines

A reusable product and engineering framework keeps the work consistent from the first idea through architecture, implementation, verification, and operation. It brings the discipline of large-scale engineering into small experiments.

Featured Work

Engineering portfolio intelligence

Delivery Guard

White-labeling & customization

Combines sprint delivery, code quality, testing, and customer support signals into a working portfolio view for a large organization.

Successfully operating dashboards expose risks and trends across teams and provide a shared evidence base for conversations with team leads.

  • Python
  • SonarQube
  • Atlassian
  • Xray

Public procurement intelligence

EIS Monitor

Tracks Latvian public procurements and turns fragmented source records, changes, documents, buyers, and suppliers into one view.

Incremental collection and targeted enrichment keep the product useful while respecting real-world source constraints.

  • Python
  • FastAPI
  • SQLite
  • Jinja

Selected Projects

How I Build

1–2 week cycle

A short Guidelines-driven product loop that moves from a real personal need to a working system exercised in practical scenarios.

01 · Idea

Start with a concrete problem or a technology worth understanding.

02 · Self-validation

Check that the idea solves a real need I experience and would actually use.

03 · Mission

Define what the product exists to change and what stays outside its scope.

04 · Use cases

Turn the mission into concrete user flows, decisions, and success conditions.

05 · AI-assisted architecture

Explore options with AI, challenge assumptions, and choose the smallest viable design.

06 · Build & exercise

Implement the system, run it through real scenarios, and refine it from evidence.
