With around 6 years of hands-on experience building and maintaining complex, production-grade systems across fintech, payments, and enterprise SaaS platforms, including distributed systems and event-driven infrastructure. Deep expertise in Java 21 and Spring Boot 3.x – including low-level engineering with Spring AOP/AspectJ, Spring WebFlux, Netty TCP servers, and gRPC-Java – combined with advanced proficiency in Node.js, TypeScript, Express.js, and Go (Gin). Proven track record integrating with financial messaging standards (ISO 20022, SWIFT), IBM MQ, RabbitMQ, and GraphQL (Apollo). Experienced with PostgreSQL, Oracle, MongoDB, MySQL, Redis, JDBCTemplate, and Flyway. Strong background in observability (Prometheus, Grafana, Micrometer), cloud infrastructure (AWS EKS, Kubernetes, Docker), security hardening, and developer-facing SDK documentation. Thrives working independently on technically deep, end-to-end projects and collaborating across diverse engineering teams.

Fintech · Payments · Distributed Systems · 6+ Years
I build backend systems that remain correct under concurrency, recover cleanly from failure, and scale across payment, banking, and enterprise workflows. My core work spans Java/Spring Boot, Node.js/NestJS, PostgreSQL, Kafka, Redis, Docker, Kubernetes, and cloud platforms.
I focus on financially correct, high-throughput services: transactional APIs, asynchronous workflows, integration boundaries, observability, resilience, and production incident recovery. I also build product-facing systems across TypeScript/Node.js and React where a workflow needs to be owned end to end.
A crypto exchange and wallet product focused on price discovery, swaps, transaction integrity, and responsive user-facing workflows.
Architecture focus: integrates market-data and exchange workflows with a service-oriented backend, persistence, and blockchain-facing operations. The product is a practical place to apply financial correctness, asynchronous processing, and secure user flows.
Java Spring Boot Node.js gRPC PostgreSQL Solidity Docker React TypeScript
A Java 21/Spring Boot modular platform for multi-tenant mobility, dispatch, payments, ledgering, and settlements.
Architecture focus: PostgreSQL/PostGIS is the system of record; Redis supports dispatch and live indexes; OIDC secures access; transactional outbox patterns make domain-event delivery reliable; payment, ledger, settlement, and webhook flows model financial state explicitly.
Java 21 Spring Boot PostgreSQL PostGIS Redis OIDC Outbox Payments
A banking-integration codebase for working through the boundary between core systems, financial messages, and downstream services.
Architecture focus: explores the operational concerns behind banking integration—validation, traceability, error handling, and resilient processing—rather than treating integrations as simple request/response calls.
Java Spring Boot REST APIs Financial Integrations PostgreSQL
An attributed open-source architecture study of a .NET CQRS and brokered-messaging platform with durable delivery patterns.
Architecture focus: inbox/outbox reliability, retries, circuit breakers, RabbitMQ, Azure Service Bus, EF Core/Cosmos DB, and OpenTelemetry-compatible diagnostics. Original project and licence are retained in the repository provenance.
C# .NET 10 CQRS RabbitMQ Azure Service Bus EF Core OpenTelemetry
An attributed Python/Django architecture study of a production-style knowledge platform with immutable revisions, word-level comparisons, search, citations, and collaborative editing workflows.
Architecture focus: Django REST Framework APIs, PostgreSQL full-text search, immutable revision history, documented design decisions, automated tests, and a React/TypeScript client. Original project and licence are retained in the repository provenance.
Python 3.13 Django 5.2 Django REST Framework PostgreSQL React 19 TypeScript Pytest
A hands-on Python and machine-learning project completed through the DevTown/ShapeAI bootcamp, documenting practical experimentation with foundational ML workflows.
Learning focus: Python-based data preparation, introductory model development, TensorFlow fundamentals, and notebook-driven experimentation.
Python Jupyter Notebook Machine Learning TensorFlow Data Analysis
A maintained open-source fork of Formance Reconciliation for comparing ledger transaction flows and external cash-pool data to surface financial discrepancies.
Architecture focus: ledger-to-provider reconciliation, financial-integrity checks, discrepancy investigation, audit workflows, and Go service design. The repository retains its upstream history and attribution.
