PostgreSQL · Redis · REST APIs · append-only ledger · relational modelling · RBAC
A financial-operations platform in production: invoices, payroll, expenses and month-end close on a double-entry, append-only ledger. Backend and data layer built for correctness and auditability — money-critical data modelling and SQL work where a mistake is not an option.
- Money-critical data model on a double-entry, append-only ledger, with an approval gate before any action executes.
- Relational schema design and query work over PostgreSQL, built to reconcile and audit every movement.
- REST APIs serving web and mobile clients; automated agents act under scoped permissions.

FYX Gaming — .NET Core Backend at Scale (CTO)
C# · .NET Core · AWS · high-throughput settlement · SQL · multi-chain
Built and ran the platform as CTO of FYX Gaming: a C#/.NET Core settlement backend on AWS moving in-game financial assets between game backends and public blockchains, settling millions of transactions a day for live titles. Game clients were C#; the backend was .NET Core — C#/.NET top to bottom.
- Owned architecture and delivery end to end: hardened a messy codebase while live, including a database migration with the system running — the same migrate-without-downtime work this kind of project needs.
- High-throughput settlement across systems on AWS; releases cut from manual hours to minutes.
- C#/.NET Core services with signature-based auth, and C# (Unity) game clients on the front.
distributed systems · consensus · replicated data · deterministic simulation
A peer-reviewed tool paper (SRDS 2026): a deterministic simulator for stress-testing consensus and replicated systems with fully reproducible traces. This is the theory under data streaming, change-data-capture and keeping databases consistent across a distributed system.
- Deterministic fault-injection simulator for replicated and consensus protocols — reproducible traces for testing data consistency.
- PhD in distributed systems; published research on Byzantine fault tolerance in replicated data.

Data & ETL Pipelines
ingestion · streaming between sources · reconciliation · SQL
- Ingestion pipelines for a cryptocurrency exchange: exchange APIs, blockchain data and scraped sources streamed and reconciled into one clean structured database — the shape of a migrate-and-aggregate project.
- Endpoint reverse-engineering where sources had no clean API; human handoff where an automated route was not safe.
Platform & Infrastructure
Kubernetes · Terraform · AWS · Docker · CI/CD
- Infrastructure as code with Terraform and container orchestration with Kubernetes, on AWS.
- Containerized delivery with CI/CD; self-hosted production stacks behind tunnels and load balancers, wired for zero-downtime deploys.
