The Problem

The company conducted performance reviews manually using spreadsheets and emails, leading to inconsistent evaluation criteria, delayed feedback cycles, and lack of visibility into team growth metrics across 200+ employees.

The Solution

Led the product vision and technical architecture for an internal performance review platform. Defined requirements through stakeholder interviews with HR and managers, designed the review workflow, built core backend services, and implemented analytics dashboards for leadership visibility.

Case Study

Context

Company-wide performance reviews were conducted manually using spreadsheets and email threads.
HR spent 120+ hours each quarter coordinating reviews across 200+ employees and 30+ managers.
Inconsistent evaluation criteria led to subjective reviews and lack of visibility into team growth.
Leadership needed data-driven insights to identify top performers and areas for improvement.

Decision

Build an internal platform to standardize and automate the entire review cycle.
Take a dual role: define product requirements AND build core backend services.
Prioritize manager experience first to drive adoption, then expand to employee self-reviews.
Design for flexibility to support both quarterly reviews and continuous feedback.

Execution

Conducted stakeholder interviews with HR, managers, and leadership to map the review process.
Designed review workflow with customizable evaluation criteria and rating scales.
Built RESTful APIs in Node.js with PostgreSQL for review data management.
Implemented role-based access control for managers, HR admins, and employees.
Created analytics dashboards showing team performance trends and completion rates.
Ran pilot with 2 departments before company-wide rollout.

Outcome

Reduced review cycle time by 60% from 6 weeks to 2.5 weeks.
Achieved 95% manager adoption within first quarter of rollout.
Saved HR team 120 hours per quarter in manual coordination work.
Enabled leadership visibility into performance trends across all departments.
Platform now supports 200+ employees with consistent evaluation standards.

Learnings

Internal tools succeed when they solve real pain points for the people using them daily.
Hybrid product-engineering roles require clear boundaries on when to switch hats.
Piloting with friendly departments builds advocates for company-wide rollout.
Analytics dashboards drive executive buy-in and continued investment.
