Paperless 📄✅

Paperless is a professional electronic document signing service designed for both individuals and corporate entities. It ensures that every signature made on the platform is 100% legally binding and recognized under Indonesian law.

Legal Compliance & Security ⚖️

The platform is built to strictly adhere to Indonesian legal regulations, specifically Article 11 of the Information and Electronic Transactions Act (UU ITE). To maintain the highest standards of trust and legality, Paperless operates under the continuous review and supervision of the Ministry of Communication and Informatics (Kominfo).

Core Technical Contributions 🛠️

As a Backend Developer on this project, I spearheaded several critical architectural enhancements:

1. PKI Infrastructure Migration

I led the migration from a basic electronic signature system to a robust solution based on Public Key Infrastructure (PKI). This involved implementing high-security cryptographic standards using OpenSSL to ensure document integrity and non-repudiation.

2. PSRE Integration (Electronic Certification Authority)

I successfully integrated the platform with PSRE (Penyelenggara Sertifikasi Elektronik), Indonesia's government-recognized certification authority. This enables every signature to be officially verified and legally authenticated at the government level.

3. Backend Architecture & Management

I developed and maintained the mission-critical backend services responsible for:

• Key Pair Generation: Securely creating public and private keys for users.
• Certificate Management: Handling the lifecycle of digital certificates.
• Signature Validation: Implementing complex workflows to verify signatures against PSRE standards in real-time.

Impact 🚀

By modernizing the technology stack and ensuring strict legal compliance, Paperless has become a trusted solution for businesses looking to digitize their legal workflows securely and efficiently.
