Debugging practice and hiring platform
Private repositoryBuglyst
Buglyst turns production-style failures into hands-on debugging labs and hiring assessments where fixes have to survive automated validation.
The product
Realistic debugging assessments built around failing code, hidden checks, and verified fixes.
Buglyst focuses on realistic engineering judgment: understand unfamiliar code, isolate the fault, patch it, and prove the behavior against visible and hidden checks.

01 · Challenge
Conventional debugging practice is frequently passive or limited to simplified examples. The platform required a coherent workflow spanning unfamiliar code, failing tests, hidden checks, and verified remediation.
02 · Approach
I developed browser-based labs, guided teaching flows, durable progress records, accepted-solution verification, and a controlled hiring interface with rotating assessment items and candidate reports.
03 · Outcome
The product includes production-style exercises, synthetic and open-source-derived problem generation, validation gates, and controlled candidate/company workflows.
Technology
Technology stack and implementation choices.
What it does
Realistic debugging assessments with starter, gold, and hidden-solution verification
Fail-closed publication rules, mutation rejection, secret scanning, and confidence gating
Narrative and grading-integrity checks before assessment publication
Candidate and company workflows with payments and GitHub integration surfaces
Problem
Hiring and practice flows often reward memorized algorithms instead of the work backend engineers actually do: reading unfamiliar code, tracing failures, and proving a fix without breaking surrounding behavior.
Architecture
The product is organized around generated assessments, validation evidence, candidate runs, company workflows, and publication gates. I distinguish implemented surfaces from production-enabled features when credentials, migrations, or flags are required.
Reliability and integrity
Assessment publication is treated as a quality gate: hidden checks, gold patches, mutation rejection, secret scanning, narrative checks, and confidence thresholds are designed to fail closed rather than publish weak material.
Trade-offs
The system favors assessment integrity over maximum generation volume. Some database-backed hiring features depend on the current production environment rather than being claimed as universally active.
