Persistent Personalised Development

The AI Developer Coach That Remembers You

Most tools score you once and forget you exist. Meridian remembers every session, watches your growth across platforms, and gets sharper the longer you use it.

The Three Pillars of Growth

Meridian builds a living profile of your engineering performance, not a static resume.

Real Data

Connect your GitHub, LeetCode, and Codeforces handles. We score actual commits, competitive ratings, and problem-solving velocity — not self-reported skills.

Multi-Signal Scoring

Our MSTS algorithm triangulates six behavioral dimensions to produce a composite parity score across different platforms and development styles.

Persistent Memory

Powered by Hindsight, Meridian remembers every session. Every sub-score, weak area, and timestamp compounds into a persistent memory of your growth.

The MSTS Composite

Multi-Signal Triangulation Score (MSTS) evaluates six independent signals to build your behavioral profile.

25%

Task Complexity

Evaluates architectural depth, dependency changes, and issue severity across GitHub contributions.

25%

Code Survival Rate

Measures technical debt by tracking what percentage of your code resists refactoring over 12 months.

15%

Issue Resolution Velocity

Weighted speed of closing critical path items, accounting for platform-specific difficulty.

15%

PR Review Depth

Tracks review cycles, cross-team impact, and the educational value of your code reviews.

10%

Cross-Repo Bonus

Multiplier for demonstrating adaptability across distinct tech stacks and repository structures.

10%

Temporal Decay

Favors consistent growth. Past glories decay, incentivizing continuous skill development.

Persistent Memory Layer

Powered by Hindsight

Hindsight SDK captures full session context — every sub-score, weak area, and behavioral timestamp. Unlike static dashboards, Meridian recalls your trajectory to compute deep insights that compound over time.

How It Follows You

Four step pipeline to persistent coaching. We connect your data, score your signals, and remember your growth.

1

Connect Platforms

GitHub OAuth + LeetCode username + Codeforces handle.

2

MSTS Scores You

Six behavioral signals produce composite 0-100 score.

3

Hindsight Remembers

Full session retained — sub-scores, weak areas, timestamps.

4

Agent Coaches You

AI recalls past sessions, trajectory, surfaces silent patterns.

Trusted by Engineers

Growth is quiet. Meridian makes it visible.

Verified Profile

"Meridian completely changed how I view my PRs. It accurately identifies high-leverage architectural shifts that used to go completely unrewarded by simple commit counts."

S

Sarah Drasner

@sarah_edo • Senior Engineer

Verified Profile

"The persistent memory via Hindsight is the killer feature. It remembered a concurrency patterns I struggled with 6 months ago and showed me how much my Code Survival rate has improved."

D

Dan Abramov

@dan_abramov • Core Contributor

Verified Profile

"I love that the coaching is data-driven. No generic advice. The MSTS score accurately identifies my weaknesses in tree traversal and suggests challenges that actually push me."
