The Problem

• Field activity, attendance, and reports were tracked manually across group chats and paper logs, with no single source of truth.
• Supervisors and administrators had no real-time visibility into what was happening on the ground.
• Roster verification was manual and error-prone, with no reliable way to confirm records against official data.

The Solution

• Built a five-role hierarchy (HQ Admin, State Coordinator, LGA Officer, PPA Supervisor, and Corps Member), each with scoped access and permissions.
• Delivered a Telegram bot for registration, logging, attendance, and reporting, so users could interact with the system without leaving a chat interface.
• Built a real-time dashboard so administrators can drill down from all states to an individual member, with live updates as new data comes in.
• Added CSV-based roster validation gated on official identifiers, so records are verified against source data before entering the system.
• Hardened the platform with strict security headers, rate limiting, IDOR testing, and verified email delivery.

The Result

• A live, production platform at copalog.vercel.app, built and demonstrated within a single NYSC service year — from concept to a working five-role system.
• Validates every roster entry against official callup numbers and state codes before it enters the system, closing a gap that manual verification couldn't.
• Routes reports and approvals through the correct role chain automatically, with no manual forwarding between officers.
• Grade A security headers, rate-limited endpoints, and tested against IDOR vulnerabilities — hardening most early-stage platforms skip.
• Positive reception at YEEP'26 from NYSC's ICT Chief, with a formal technical report requested for the Deputy Director of ICT.

What this does not claim

• The platform is deployed and working, but it is not an officially adopted NYSC system. It was demonstrated to officials and awaits a decision, and no organisational rollout has been agreed.

Stack

Inside the platform

State-by-state breakdown with live verification rates.

National impact view — corps members, active PPAs, and verified logs at a glance.

Roster upload — CSV records validated before they ever reach a corps member's registration.

Callup number and state code are checked against the uploaded roster at registration.

LGA Officer view — session codes, attendance counts, and group history.

Corps Member view — a full year of CDS attendance in one calendar.

Every session generates a unique code and a timestamped attendance record.

Built-in inbox — official communication without leaving the platform.

Every submission gets a unique reference ID — nothing gets lost or disputed.
