Senior Backend, Full-Stack, and Platform Engineer
I build production-grade systems with a focus on backend architecture, integration boundaries, async workflows, data and reporting services, and operator-facing reliability tooling. This profile is organized around an eight-repository public portfolio that shows how I approach secure application delivery, service operations, and platform readiness.

I work best on systems that need more than straightforward CRUD. That includes permissioned workflows, auditability, webhook and event processing, queue-backed orchestration, analytics pipelines, and the operational interfaces needed to run services confidently.
Across the public repositories, the through-line is clear boundaries: secure APIs, integration handling, replay-safe async processing, SQL-first reporting, operational visibility, Linux and Docker fluency, and practical delivery environments that are built to be operated.
| Scope | What It Looks Like |
|---|---|
| Backend systems | API-first services for business workflows, policy enforcement, access control, and audit-ready change tracking |
| System design | Clear service boundaries, ownership models, reliability concerns, and maintainable operational interfaces |
| Integrations | Webhook ingestion, normalization, idempotency, delivery tracking, retries, and external contract management |
| Async processing | Queues, workers, stateful orchestration, reminders, notifications, replay, and recovery paths |
| Data and reporting | SQL-heavy query design, aggregations, scheduled recomputation, cache control, and reporting endpoints |
| Ops tooling | Health and status models, retry controls, incident workflows, diagnostics, and operator-facing APIs |
| Platform and delivery | Dockerized environments, Linux operations, reverse proxies, CI/CD, and infrastructure automation labs |
| Area | Technologies |
|---|---|
| Backend and services | PHP, Laravel, Symfony, TypeScript/Node.js, NestJS, Go, Java, Spring Boot |
| Frontend surfaces | React, Next.js |
| Data and messaging | PostgreSQL, MySQL, Redis, RabbitMQ, SQL-first modeling, caching |
| Infrastructure and delivery | Docker, Docker Compose, Linux, Apache, Nginx, Kubernetes, Terraform, Ansible, GitHub Actions, Azure DevOps, LocalStack |
| Delivery style | REST APIs, WebSockets, validation and policy layers, testing, queue-backed workflows |
The portfolio is intentionally broad but cohesive: secure backends, orchestration, integrations, realtime operations, analytics, monitoring, Linux infrastructure, and platform delivery.
| Repository | Primary Focus | Why It Matters | Stack |
|---|---|---|---|
| deal-room-api | Secure deal-room backend | Shows permissioned document workflows, scoped sharing, and audit-ready backend design | PHP, Laravel, MySQL, Redis, Docker |
| conference-orchestrator | Event and call workflow orchestration | Shows lifecycle control, participant coordination, and queue-backed workflow execution | PHP, Symfony, PostgreSQL, Redis, RabbitMQ, Docker |
| integration-gateway | Webhook ingestion and integration processing | Shows clean integration boundaries, canonical event handling, idempotency, retries, and replay-friendly delivery | TypeScript, Node.js, PostgreSQL, Redis, RabbitMQ, Docker |
| realtime-ops-platform | Realtime operations microservices | Shows event-driven operational workflows, queue-backed processing, and realtime service updates | TypeScript, NestJS, PostgreSQL, Redis, RabbitMQ, WebSockets, Docker |
| pg-analytics-service | Query-heavy analytics service | Shows SQL-first analytics design, scheduled recomputation, and predictable cache and version handling | Go, PostgreSQL, Redis, Docker |
| ops-monitor | Operational monitoring and intervention API | Shows operator-facing reliability tooling with health checks, retry workflows, status models, and audit trails | Java, Spring Boot, PostgreSQL, Redis, Docker |
| linux-infra-lab | Linux and infrastructure operations lab | Shows reverse proxying, automation scripts, backup and restore runbooks, and service diagnostics | Linux, Bash, Apache, Docker Compose, Node.js, PHP, MySQL, PostgreSQL, Redis |
| platform-delivery-lab | Platform delivery and DevOps lab | Shows infrastructure automation, CI/CD workflows, Kubernetes-style delivery, and local cloud-oriented platform tooling | Docker, Kubernetes, Terraform, Ansible, LocalStack, Apache, Nginx, GitHub Actions, Azure DevOps |
- deal-room-api for permissioned backend workflows, document access boundaries, and auditability.

| Pattern | How It Shows Up |
|---|---|
| Access control and auditability | Scoped permissions, policy enforcement, audit logs, and traceable operator actions |
| Async workflows and recovery | Queues, workers, retries, replay paths, lifecycle orchestration, and failure visibility |
| Data and reporting systems | Aggregations, reporting endpoints, scheduled recomputation, SQL-first modeling, and cache discipline |
| Platform and delivery workflows | Docker, Linux, reverse proxies, CI/CD, infrastructure automation, and environments designed to be operated |
Public repositories are only one part of the profile. LinkedIn-backed experience also includes delivery in product, contract, and freelance environments where source code is not public.
- Full-stack product work with React and Next.js frontends backed by Node.js and PHP services
- API integrations and workflow automation across content, CRM, and business operations use cases
- SQL and NoSQL data work involving query tuning, caching, backend refactors, and reliability improvements
- CI/CD, containerized environments, release workflows, and AEM-based enterprise delivery involving component systems, dispatcher and cache concerns, and content operations
- Backend architecture with explicit reliability, ownership, and operational clarity
- Async workflows with retries, replay, failure handling, and observable service behavior
- Integration-heavy systems with clean contracts between internal and external services
- Platform delivery practices spanning containers, Linux operations, and infrastructure automation
