Full-Stack Engineering · Node.js · Laravel · Vue

I build backend systems, APIs, integrations, and full-stack product features with Node.js, Laravel, Vue, PostgreSQL, MySQL/MariaDB, and Redis. I'm comfortable working across new builds and existing production systems, with a focus on clean architecture, reliable delivery, and maintainable software.

Portfolio focus

Where I spend most of my time

Node.js-heavy backend work first; details shift with product needs. For depth on tools, jump to Tech stack.

Backend services & system architecture

I build service-oriented backend systems with clear API boundaries, async workflows, queues, and database structures that support growth without adding unnecessary complexity.

  • Service boundaries
  • Queues & async flow
  • Clear APIs

Node.js APIs & integrations

Node.js backends for REST APIs, workers, internal tools, external integrations, and product features that need reliable data flow and clean ownership.

  • REST APIs
  • Workers
  • Third-party hooks

Data that fits the product

PostgreSQL, MySQL-family engines, MongoDB, and Redis: schema evolution, sane indexing, caches, and trade-offs spelled out upfront.

  • PostgreSQL
  • Redis
  • Indexing & migrations

Approach

I start from the product and the system constraints, then choose the simplest architecture that can scale. Sometimes that means a focused Node.js service, sometimes a Laravel/Vue feature, sometimes a queue, integration, or database improvement. The goal is practical progress without creating unnecessary operational weight.

Capabilities

What engagements tend to include

Backend services and APIs with Node.js, product-facing features full-stack where needed, integrations, and Laravel/PHP or Vue surfaces when those tools match the roadmap. Practical delivery, incremental risk, readable code.

Backend services & software architecture

Service-shaped backends with explicit API boundaries, async paths and queues when they earn their keep, and persistence that scales with the product. Microservice-style decomposition is one option among many when constraints call for it.

Internal Process Optimization

Streamline your business operations by eliminating paper-based processes, reducing email overload, and consolidating communication channels into efficient digital workflows.

LLM Integration & Solutions

Implement Large Language Model solutions to enhance your business operations and customer interactions, including chatbots, document analysis, and content generation.

Legacy System Modernization

Transform older systems toward maintainable architectures and clearer modules, using stacks that fit the team, without a forced migration storyline.

Technical Consultation

Get expert guidance on technology strategy, system architecture, and implementation approaches tailored to your specific business needs and goals.

Full-Scale Development Team

Access a dedicated team of experts for major application development projects, from initial planning to deployment and maintenance.

Custom Software Development

Build bespoke software solutions tailored to your unique business requirements, from small productivity tools to enterprise-grade applications.
