Rewards Engine — multi-tenant B2B loyalty & rewards platform powering the white-label products MjPoints and TwoXPoints from one shared backend.– Delivered the backend to its first production release, serving two separately branded consumer products from a single .NET 10 codebase with per-brand white-label composition.– Own the Campaigns bounded context end to end — one of 11 modules in a NetArchTest-enforced Clean Architecture monolith — from domain model and referral codes through CQRS handlers, EF Core schema, admin search endpoints and outbox-published integration events, shipped with unit, integration and architecture tests.– Hardened cross-module event delivery by making the transactional Inbox/Outbox pipeline retryable over MassTransit and RabbitMQ, with Quartz.NET-scheduled queue processing.– Helped migrate the monolith from .NET 8 to .NET 10 and extend permission-code RBAC across Administrator, Brand, Distributor and Merchant roles.– Continue to maintain the ClearLine retail loyalty platform part-time alongside Rewards Engine delivery.– Stack: .NET 10 / C# 14, PostgreSQL (Npgsql + EF Core, Dapper for read paths), Redis, RabbitMQ / MassTransit, Quartz.NET, MediatR, FluentValidation, .NET Aspire, Serilog + Seq, OpenTelemetry, xUnit v3, Docker, Google Cloud Run.

A4Real — productivity and self-management SaaS that turns long-term goals into an executable daily plan, with focus sessions, rituals, adaptive rescheduling and XP-based gamification.– Designed and built the entire product solo: a .NET 8 Clean Architecture backend (CQRS with MediatR, EF Core on SQL Server) and an Angular 21 signals-based SPA localised in three languages.– Unified four separate scheduling subsystems onto a single event-driven Trigger primitive through a staged dual-write migration with zero data loss, backed by Quartz.NET materialisation, SignalR real-time push and Firebase Cloud Messaging.– Built authentication around short-lived access JWTs plus opaque, single-use rotating refresh tokens with reuse detection and family-wide revocation; established codebase-wide ownership scoping with cross-user tests, closing real IDOR defects.– Shipped an Android app via Capacitor with an owned native Kotlin plugin — exact alarms, a full-screen ringing activity and boot re-arming — so scheduled rituals fire reliably under Android Doze.– Adopted AI-assisted delivery in 2026 — repo-scoped Claude Code agents and machine-enforced architectural conventions — significantly raising shipped features per month.

ClearLine (a SurgePays company) — point-of-sale digital marketing automation platform: SMS/email campaigns, digital coupons, loyalty and referral programs, customer-facing in-store screens and POS integration for retail and multi-location businesses.– Built the product from scratch as its sole developer — both the Angular frontend and the .NET backend — and grew it into a platform serving 1,000 merchants, developed by a 15-person team and acquired by SurgePays (NASDAQ: SURG).– Architected an Nx monorepo of 4 Angular applications and 6 shared libraries: an admin console, a real-time in-store customer-facing display PWA, a marketing/campaign console, and public embeddable loyalty pages.– Built a modular .NET 8 backend deployed as independent Docker services, including a custom IdentityServer4 OAuth2/OIDC provider with Google, Facebook and LinkedIn login.– Integrated 4 POS providers (Clover, Cova, Pax, Surge) and 6+ messaging and loyalty SDKs (Twilio, InfoBip, TwoReward, Vendasta, Courier) behind one unified platform API.– Owned deployment infrastructure and CI/CD: Bitbucket Pipelines with format and lint quality gates, unit tests, and per-service Docker builds across 10+ deployment environments.– Set technical direction for the team — code review, refactoring and architecture decisions; established Jest-only testing and RxJS-based state composition as codebase-wide standards.– Stack: Angular 18, RxJS, Nx 20, Jest · .NET 8, EF Core 8, MySQL, MongoDB, IdentityServer4, GCP, Kubernetes (GKE), Docker.

Delivered C#/.NET back ends and JavaScript, AngularJS and Angular front ends across seven client products in SaaS, telecom, logistics, marketing and e-learning.– Built adaptive web interfaces in HTML5, CSS3/SCSS and Bootstrap, and desktop tooling in WinForms and WPF.– Gathered and formalised requirements directly with customers, then maintained and extended long-lived production solutions.– Selected products: PortaSwitch (converged telecom platform), PageFlex (localised marketing platform), CodeFuse (cloud test-automation SaaS), VentGlobal (freight-exchange portal), Nexans Switch Manager (WinForms/WPF), Fabo, New School.
