The systems behind the work.
Most of what I have built is either under client confidentiality or too infrastructure-heavy to keep running publicly. So rather than link to dead demos, each system is documented here by its engineering: how it is put together, the decisions that shaped it, and an interactive walkthrough of the flows that matter.
One structure
Every project uses the same sections and the same diagram language, so very different systems become comparable.
Counted, not claimed
Scale figures are read off the repositories — files, lines, modules, services. No rounded-up numbers.
Client-safe
Systems are described generically. No client names, no brands, no credentials, no private endpoints.
Provably-Fair iGaming Platform
A real-money gaming platform with a server-side provably-fair engine, a full affiliate subsystem, crypto cashier and identity verification — roughly 180k lines across fifty bounded contexts.
Decentralized Prediction Market Platform
A four-service prediction market where users trade outcome shares on-chain, with an AI evidence pipeline proposing resolutions for human sign-off.
Social Forecasting & DeFi Liquidity dApp
A forecasting game bolted onto real DeFi liquidity: users predict price outcomes, a worker fleet scores them against oracle data, and a dedicated reward engine distributes the results.
Multi-Tenant P2P Trading Marketplace
A white-label peer-to-peer trading engine that other operators embed into their own products, exposed entirely as APIs their backends consume.
Cross-Chain Interoperability Node
A layer-one node that speaks to half a dozen foreign chains natively, with post-quantum signatures and zero-knowledge primitives built into the base layer rather than bolted on.
Multi-Tenant Slot Game Provider
A standalone slot provider: operators integrate over an API, games run inside a sandboxed iframe, and outcomes are decided server-side by renderer-agnostic math packages.
Hierarchical Casino Operator Platform
An operator platform built around a tree of administrators rather than a flat admin role, where balances move by manual credit and debit between levels instead of through a payment gateway.
Adaptive AI Tutoring Platform
A local-first tutoring platform where uploaded course material becomes searchable knowledge, and lesson generation runs as a resumable graph rather than a single prompt.
Legal Research & Compliance Assistant
A decision-support system for legal research where every answer traces back to a content-addressed snapshot of an official source, and an ingestion policy gate decides what is allowed into the corpus at all.
Self-Hosted AI Agent Orchestrator
A Go control plane that drives existing local AI coding CLIs through a plan → work → verify → retry workflow, with shared agent profiles that live outside the repositories being worked on.
Multi-Chain & Post-Quantum SDK Suite
A client SDK family that hides six blockchain ecosystems and two signature generations behind one interface, so application code does not have to know which chain or which cryptography it is talking to.
Post-Quantum Browser Wallet Extension
A browser extension wallet where keys never leave an isolated background context, and accounts can be bound to post-quantum signature schemes.
Configuration-Driven Developer Platform
An internal platform that turns a whole multi-service development environment into one configuration file, so onboarding a developer is a clone and a command rather than a day of setup.
On-Chain Prediction & Reward Contracts
A Solidity suite covering prediction pools, bonding-curve pricing, staking and reward distribution, deployed through a declarative pipeline with a tracked address registry.
Quant Strategy Validation Bench
A research harness for binary-outcome trading strategies, built specifically to disprove them — it optimises for expectancy, ships a coin-flip control, and places no real orders.
Web3 Incentives & Quest Platform
A campaign platform where users complete on-chain and social quests to earn allocations, with layered anti-abuse so the rewards reach people rather than scripts.
Autonomous Agent Commerce Rail
A working demonstration of software agents paying each other per API call, with cryptographic identity, an enforced spending allowance and a receipt for every transaction.
Layer-2 Privacy Subnet Application
A client application demonstrating private transaction flows inside a permissioned subnet, where activity stays confidential between members and only a periodic rollup reaches the public chain.
Agent-to-Agent Deferred Settlement
A buy-now-pay-later and subscription rail for autonomous agents, where the credit relationship stays private inside a permissioned subnet while settlement is publicly verifiable.
Blockchain Indexing Layer
Three subgraphs that turn raw contract events into a queryable API, so applications can ask questions the chain itself answers slowly or not at all.
Decentralised Identity Verification Service
A small, deliberately narrow HTTP service that verifies and looks up on-chain identity attestations — hardened well beyond its size because it sits on an authentication path.
