From Concept to Reality.

Tangbls is a trusted-records platform for valuable physical objects, bringing together ownership, provenance, valuations, insurance, private sales, and verifiable digital passports. I led the architecture for its secure, event-driven platform, combining auditable workflows, controlled evidence sharing, and independently verifiable blockchain anchoring.

I architected and developed a distributed media intelligence platform of about ten microservices for large-scale ingestion, fingerprinting, and similarity-based search across images, videos, and archives. I built high-performance Rust microservices, Kafka-based processing pipelines, and ClickHouse analytics infrastructure designed for petabyte-scale datasets and billions of hashes per month. I implemented perceptual hashing algorithms to identify duplicate and visually similar content, even across modified or transformed media, with a focus on scalability, processing efficiency, and low-latency retrieval.

I designed GoToCrypto, an event-driven crypto trading and operations platform that turns live market data into validated, risk-controlled trades on Hyperliquid. It combines live and paper trading, end-to-end reconciliation, audit trails, market-data recovery, PnL analytics, and a secure operator console. It is built around correctness, observability, and safe recovery from failure.

I led development of a multi-chain DeFi portfolio analytics and accounting platform in a SOC-compliant environment, building on Venato, the product Lukka acquired. It tracks wallet activity, reconstructs complex investment strategies and calculates historical portfolio valuations and profit and loss across approximately 100 DeFi protocols. I designed Kafka pipelines that process Ethereum transactions at scale to derive wallet-level net worth and asset exposures, with finality-aware block processing that stays accurate through chain reorganisations. I built automated asset pricing engines, including discovery of liquidity pools and valuation of non-tradable derivative tokens by reverse-engineering smart contracts, and a hybrid infrastructure that runs blockchain nodes on dedicated hardware while services scale in the cloud. The platform supports auditable portfolio reconciliation, investment performance analysis, and tax reporting.

I designed and developed KeyFi Ledger Adapter, a blockchain infrastructure and wallet integration platform providing a unified API across more than 15 blockchain networks. I built transaction signing and policy-based approval workflows, integrating secure cryptographic key management with Unbound CASP/UKC vault technology. I deployed and managed full and archive blockchain nodes across supported protocols, ensuring reliable access to on-chain data and transaction execution. I architected bare-metal Kubernetes infrastructure with Ceph distributed storage, automated provisioning, and Jenkins CI/CD pipelines for testing and deployment.

I designed and developed Stratis blockchain protocol testing and debugging infrastructure, focused on network resilience, consensus validation, and adversarial testing. I built custom Bitcoin-based clients, P2P protocol analysis tools, and managed blockchain test networks to detect forks, network splits, and consensus failures. I implemented network simulations covering malformed messages, invalid transactions, DoS scenarios, and adverse network conditions. I extended Bitcoin Core components and developed cryptographic solutions using ECDSA, zero-knowledge proofs (ZKP), and TumbleBit, alongside custom Wireshark tooling for low-level protocol analysis.

I designed and delivered enterprise automation, data validation, and regulatory reporting solutions for major UK banks, supporting BCBS239 and IFRS9 compliance. I developed C# frameworks for financial data reconciliation, business rule validation, ETL orchestration, and operational monitoring. I led technical delivery within a large-scale transformation programme targeting automation across around 2,700 applications, defining automation strategies, frameworks, and engineering standards. I built automated testing infrastructure spanning APIs, messaging systems, trading platforms, and financial applications, including SWIFT transaction simulation, large-scale test data management, and performance testing. I combined hands-on software engineering with technical project leadership, improving data quality, regulatory controls, and delivery efficiency across complex banking environments.
