Experience
AI-powered Enterprise Platform
I replaced the monolith with cloud-native microservices on Azure, then built a centralized OAuth2/OIDC authorization server on ASP.NET Core Identity and OpenIddict to provide SSO and standardized API security across those services. With that foundation in place, LLM-powered capabilities could be added as independent services rather than embedded changes to a fragile core.
On top of that platform, I built AI workflows that automate document processing, classify incoming requests, and surface decision support to operators, running against live business data rather than as isolated prototypes.
I defined the architecture and stayed hands-on through implementation, cloud infrastructure, and production release, using agentic coding tools, including Claude Code and Codex, to accelerate delivery without compromising code review or architectural standards.
Enterprise Identity Platform
I designed and built a centralized OAuth2/OIDC authorization server on ASP.NET Core Identity and OpenIddict, rather than adopting an off-the-shelf identity provider, giving full control over token issuance, user store integration, and the client registration model.
I stayed hands-on throughout by building the core identity services, implementing the authentication and consent flows, and making the architectural calls on token lifetime, scope design, and refresh token handling.
The result was SSO across the client's customer-facing and internal applications, standardized API security for every downstream service, and a foundation that new applications could adopt without implementing authentication themselves.
Cloud-native Travel Platform
I architected and led the migration to a cloud-native microservices platform built on ASP.NET Core and Kubernetes, decomposing the monolith into independently deployable services, including identity, mobile, Data Factory, and background services. RabbitMQ handled asynchronous messaging, and Redis provided distributed caching, so heavy read paths and background processing no longer competed with request handling.
I built a centralized identity platform on IdentityServer4 to replace per-application authentication, enabling SSO and standardized API security across the estate.
Beyond the architecture, I stayed in the code, building core services and establishing engineering standards for automated testing, API documentation, structured logging, and code review while mentoring the team through the transition.
Teams could deploy independently rather than coordinating a single release, and components could scale to match demand instead of the whole application scaling together.
Digital Banking Platform
I architected and delivered services across digital banking, ATM operations, payment processing, and SWIFT-based enterprise integration, building reusable enterprise services and APIs with C# and WCF against Oracle, DB2, and SQL Server environments.
I built an image detection service on Azure Cognitive Services, training custom vision models on labeled image sets to return match confidence scores to consuming banking applications.
Performance work focused on the transaction path, including optimizing application architecture, logging infrastructure, and transaction processing under high-volume conditions. I also introduced DevOps practices by building deployment automation tooling that shortened release cycles and reduced manual steps.
Alongside the engineering work, I guided teams through architectural decisions and technical reviews and delivered internal technical training across the organization.
Multi-bank Payment Gateway
I built enterprise payment gateway solutions spanning 13+ bank integrations, applying SOA so each institution sat behind a consistent internal contract while its specifics stayed isolated in its own adapter.
The processing layer ran on WCF services and Windows Services, with Quartz scheduling recurring settlement and reconciliation, as well as background operations, against SQL Server. High-performance data access layers built with LLBLGen Pro supported transaction volumes for banking, telecommunications, and public-sector clients.
I worked across back-end services, enterprise integration, and payment processing automation, designing the integration architecture and writing the services that ran it.
The result was reliable transaction processing across a heterogeneous set of banking systems, with new institutions onboarded against an established integration pattern rather than as bespoke work each time.
Capital Markets Trading and Risk Management Platform
I architected and built enterprise capital markets applications supporting FX trading, portfolio management, customer profiling, and business intelligence.
The integration work connected external market data providers, MetaTrader, and FIX-based financial systems, reconciling different message formats, session semantics, and connectivity models into a consistent internal representation that the trading applications could work against.
Back-end services and RESTful APIs were built on C#, ASP.NET MVC, Entity Framework, and SQL Server, with attention to the latency-sensitive paths where request handling sat between a user action and a market operation.
I also delivered the reporting and business intelligence layer, including operational monitoring, performance analytics, and executive reporting, that let the business view trading operations and system behavior in one place.
IoT Fleet and Telemetry Platform
I built IoT and telemetry platforms handling vehicle tracking, industrial automation, smart devices, and remote monitoring, ingesting continuous position and sensor data from field equipment into centralized management systems.
The real-time GPS tracking and navigation layer integrates mapping services with back-end telemetry infrastructure, giving operators live visibility into fleet positions and asset status, rather than relying on periodic reports.
Back-end services were built on C#, ASP.NET, WCF, and SQL Server to handle device management, data collection, and the communication layer between field hardware and central systems.
Municipalities, logistics operators, and industrial organizations used the platforms to monitor assets and automate field operations across the public sector, industrial automation, retail, and smart device deployments.
