Selected work · Confidential by default

Projects built for real operational environments.

A look at the systems, constraints, architecture areas, and delivery responsibilities behind recent digital asset, identity, wallet, and enterprise engineering work.

Client names, commercial data, and sensitive implementation details are withheld where confidentiality applies.

Case 01

Regulated Gold Tokenization Platform

Context

A platform designed to represent physical gold through permissioned digital assets while coordinating investor identity, payment, custody, issuance, transfer controls, sale, and physical redemption.

Challenge

The platform had to keep asset ownership, token supply, participant eligibility, payment state, and operational records consistent across multiple services and external parties.

Constraints

Permissioned ownership and transfer
Identity-linked investor participation
Physical and digital asset reconciliation
Multi-role operational approvals
Payment and redemption workflows
Auditable administrative activity

Architecture areas

Identity and onboarding services
ERC-3643 token infrastructure
ONCHAINID integration
Asset and issuance services
Payment orchestration
Custody and reconciliation workflows
Administrative and trustee operations
Event and audit processing

Technology and standards

TypeScript · NestJS · PostgreSQL · Solidity · Foundry · ERC-3643 · ONCHAINID · EVM

Case 02

Enterprise Digital Identity and Recovery Platform

Context

A consumer identity platform combining verified identity, secure credential storage, breach monitoring, recovery workflows, partner integrations, and consent-driven interactions.

Challenge

The system had to coordinate privacy-sensitive information, device security, external identity providers, banks, telecom providers, insurance workflows, and large-scale threat intelligence.

Constraints

Privacy-sensitive identity information
Secure on-device storage
Multi-level recovery
High-volume monitoring and matching
Multiple external institutions
Consent and approval requirements
Regulatory and security obligations

Architecture areas

Identity verification
Verifiable credential issuance
Mobile wallet and secure storage
Recovery orchestration
Threat ingestion and matching
Alerts and case workflows
Partner integration services
Consent and audit systems

Technology and standards

Verifiable Credentials · Mobile SDKs · TypeScript · Event-driven systems · Secure device storage · Cloud infrastructure

Case 03

Institutional Reward and Wallet Infrastructure

Context

A multi-tenant custodial reward platform enabling organisations to issue locked digital rewards, manage user balances, apply lock policies, and support controlled withdrawal to external exchanges.

Challenge

The platform required secure authorisation across backend services and smart contracts while maintaining tenant isolation, reliable automation, and operational control.

Constraints

Multi-tenant isolation
Locked and unlocked balances
Signature-controlled withdrawals
Exchange account validation
Automated execution and retry
Contract and database consistency
Administrative freeze and override controls

Architecture areas

Tenant API and authentication
Reward and balance services
Smart contract registry
EIP-712 signing service
Withdrawal automation
Blockchain event listener
Exchange integration
Administrative and audit tooling

Technology and standards

NestJS · MongoDB · Solidity · EVM · EIP-712 · AWS · Event processing
