Evidence is not demand
Every conclusion retains its evidence family, coverage, and confidence. The product separates what was observed from what may reasonably be inferred.
Scopova
A production pilot that detects early product momentum while keeping evidence quality, uncertainty, and collection cost visible.
Find products worth investigating without pretending public signals prove demand.

THE CHALLENGE
Why this was hard
01
Popularity rankings surface products after momentum is already obvious.
02
Public storefront signals are incomplete and must not be misrepresented as sales.
03
Paid collection can make a technically valid product economically unsustainable.
MY ROLE
What I owned
- Defined the target workflow, MVP boundary, and acceptance criteria.
- Designed signal families, confidence rules, cold-start behavior, and evidence coverage.
- Set collection budgets, rate limits, idempotency requirements, and operating safeguards.
- Directed architecture and releases, then verified them through tests and production checks.
KEY DECISIONS
The choices behind the system.
Cold start stays visible
New products first establish a historical baseline. Insufficient history is displayed as a state, not hidden behind a manufactured trend.
Cost is product correctness
Daily limits, request ledgers, rate controls, and idempotency checks run before paid collection. Sustainable evidence gathering is part of the design.
VERIFICATION
Claims tied to evidence.
Every figure carries its scope. Strong evidence includes the boundary around what it does—and does not—prove.
- Next.js, FastAPI, Celery, PostgreSQL, Redis, Docker, and Alembic across a multi-service deployment.
- Hourly trend recomputation with discovery every six hours during the controlled pilot.
- CI covered strict typing, unit and integration tests, service dependencies, frontend build, API contracts, and secret scanning.
- Encrypted daily backups with documented download, checksum, and restore verification.
OUTCOME
What changed
Scopova reached a controlled production pilot with repeatable collection, deterministic scoring, measurable operating cost, and an audit trail behind each signal.
Scope note
Pilot figures describe controlled coverage, not proven sales or broad market traction.
REFLECTION
What I learned
Market-intelligence products earn trust by exposing uncertainty.
Collection economics must influence scoring from the beginning.
A narrow observable pilot is stronger than broad unverified coverage.
