Developer intelligence, measured

Turn commits into Developer DNA

CodeDNA digests raw GitHub activity, system architecture and commit rhythm into a single measurable score — then tells you exactly what to learn next.

The RefactorIQ feedback loop

JavaParser ASTs in, measurable gains out. Six deterministic stages — no seeded repos, no synthesized scores, no LLM guessing.

  1. Analyze

    JavaParser builds the full AST — decision trees, nesting & coupling.

  2. Explain

    Hotspots get a root cause: why the code is risky, not just that it is.

  3. Recommend

    Practical patterns — Extract Class, Guard Clauses, named in order.

  4. Refactor

    Interactive diffs preview every safe transformation before you apply it.

  5. Re-analyze

    The same engine re-inspects and verifies every metric path.

  6. Gain

    32.9% average complexity gain — with zero regressions.

Analyze live — pasted code or a GitHub repo

RefactorIQ runs the same deterministic JavaParser + rule engine on every input. Empty states tell you what to do next, never fake numbers.

The platform

Built like a nervous system

DNA Score Engine

Five weighted signals collapse into one 0–100 number. Composite scoring recomputes the moment a Kafka event lands — your dashboard just updates.

Scoring Engine :8084

GitHub Integration

Repos, commits, languages and orgs — synced through a revoke-anytime OAuth token.

Repository Service :8082

Advanced Analytics

Trends, language mix, quality metrics and contribution heatmaps — live.

AI Recommendations

Your profile becomes a ranked study plan — what to learn next for your career.

Recommendations :8085

Real-time by design

Kafka decouples ingestion from scoring; WebSocket streams the new score straight into your browser. No refresh. No waiting room.

WebSocket /ws

Secure Authentication

JWT with BCrypt hashing. Read-only scopes, token in your browser only.

Auth Service :8081
Under the hood

One gateway, one event stream

Every service sits behind one gateway and talks over a Kafka event stream — so scoring never blocks a request, and a new score reaches your browser the moment it lands.

The score

Inside your DNA score

Every repository you connect feeds five weighted signals. Together they resolve into a single number out of 100 — and a ranked list of what to learn next.

Five weighted signals, one composite score

  • Code volume

    25%

    Commits, additions and deletions across every repository you own or contribute to.

  • Language breadth

    20%

    How many ecosystems you actually ship in — and how deep each one runs.

  • Commit consistency

    20%

    Rhythm beats bursts: a steady streak scores above one heroic weekend.

  • Collaboration

    20%

    Pull requests, reviews and issues — the work that happens with other people.

  • Code quality

    15%

    Tests, documentation and structure, read straight from the repositories themselves.
