Vacancy Index
Allowed sources enter ingestion, normalization, taxonomy, deduplication and freshness gates before a vacancy reaches the catalog.

HRTECH · DATA PLATFORM · EXPLAINABLE AI
Do not search with old words.Understand the real match.
A specialized HRTech platform that joins a current Vacancy Index, structured Talent Card and Talent Spec, and an explainable matching architecture across five deep-tech verticals.
FOR A PROFESSIONAL
The market is scattered; a résumé is too flat.
Vacancies repeat across sources, close without notice and use incompatible job titles. A static PDF does not express depth of skill, production responsibility or evidence of experience.
FOR AN EMPLOYER
A flow of texts is not a qualified shortlist.
Keyword search cannot reliably distinguish a passing mention from deep production experience. A single opaque AI score adds false certainty instead of explaining a decision.
THREE PRODUCT LAYERS
Current data, structured market sides, explainable match.
Talent Card / Talent Spec
Professionals and employers receive mirrored structured models instead of two incompatible free-text documents.
Explainable Match
Must-have coverage, strengths, gaps, quality of data and reason codes are shown separately from the final human decision.
FIVE VERTICALS
A market taxonomy, not a generic job-board category.

Vacancy Index
Employer Claim Loop
A verified representative can claim a prepared company asset built from permitted public vacancies, receive a workspace and take ownership of direct vacancy workflow. Candidate data remains private until explicit consent.
company → domain verification → invite → workspace
Portable data, not platform lock-in.
Talent Card and Talent Spec are designed as versioned JSON that their owners can export into compatible HR systems. Monetization belongs in workflow and results, not in blocking access to a person’s own data.
MY ROLE
Founder-built HRTech product and platform architecture.
I formed the 4ITX product model, built the Russian Vacancy Index and designed the path from disconnected prototypes to a two-sided production platform: ingestion, taxonomy, Talent Card, Talent Spec, explainable matching, employer commerce, privacy, state machines and a vertical-slice delivery roadmap.
