Critical Risks

P0

Security Issues Need Attention

Open vulnerabilities from pentest findings. Dependencies need updates.

P1

AI Single Provider Dependency

All AI features depend on OpenAI. Has retry/timeouts, but no multi-provider fallback.

P1

Hidden Dependencies

Changes in one area unexpectedly break other areas. Hard to predict impact.

P1

Teams Can't Ship Independently

Services too interconnected. Changes require coordination with other teams.

02 Service Maturity (5-Dimension Scoring)
welcome-accounts Best Tests
5.3 /10

Only repo that tests business rules (auth lockout, password history).

llm-gateway Critical
3.2 /10

Has resilience (5/10), but no events (1/10), duplicates wttj_ai.

ats-backend Critical
4.3 /10

BEST app layer (features/queries/dtos), weak resilience (2/10).

03 Frontend Maturity (5-Dimension Scoring)
sourcing-front Best
7.6 /10

Reference implementation - perfect API isolation, feature-based clean architecture.

wttj-front Average
5.4 /10

Replacing wk-front. GraphQL-first, needs test coverage improvement.

welcome-jobs-front Average
5.0 /10

LOW: 33 tests, 1 keyboard handler, lowest ARIA count (23).

Frontend Gaps: 5 of 7 repos have zero code splitting, 4 of 7 have TypeScript strict mode disabled, keyboard navigation critically underdeveloped.

05 Organizational Assessment

Top Themes from 37 Interviews

Strategic Clarity
Needs Focus

Unclear if migration is for consolidation or revenue

Scope Creep
High

Pricing added Dec without tech input, constant reprioritization

Staffing
Critical

1 QA, 1 SRE for all. 3-4 missing on ATS. Key departures.

Technical Excellence
Workshops & Coaching

Hands-on sessions covering clean architecture, testing best practices, and code quality patterns.

Evidence-based approach: All findings are reproducible. Highest code quality service (Sourcing) used as internal reference baseline. View full report →
