Lead AI Engineer | AI Systems & Workflow Architect | LLM Integration Specialist
I design and build AI-powered workflows and scalable pipelines, integrating LLMs and multi-agent systems into production-ready solutions for enterprise clients.
Currently involved in multiple client projects and shaping end-to-end AI-powered solutions across different domains.
On-demand consulting and development, focused on maintaining key internal platforms and supporting strategic integrations.
Since May 2025, I've been supporting Iyuno as an on-demand consultant, focusing mainly on OpID (delivery platform) ongoing development and providing maintenance, bug fixes, and technical guidance when needed.
Responsible for strategy, partnerships, and business growth of the company as a leading B2B distributor.
Designed and delivered AI-powered pipelines for transcription, audio processing, and QA automation. Integrated LLMs and speech technologies into enterprise-grade workflows.
Developed backend APIs and microservices for payment workflows and internal transfer systems. Focused on PHP, OOP best practices, and Agile methodologies.
Built high-traffic backend systems and maintained legacy PHP applications. Improved system performance and supported integration with external APIs.
Developed a PHP-based application and configured servers for PCI/DSS compliance as part of a credit monitoring platform project.
Created dozens of websites and e-commerce solutions for local businesses. Managed full-stack development, client relations, and project delivery.
Developed web solutions for the healthcare sector using Classic ASP, VBScript, and C#. Contributed to several critical enterprise applications.
Built and maintained the company's first online platform showcasing diving courses and services, introducing a new digital presence for the business.
I build AI-driven systems end-to-end, from POCs to production-grade solutions, integrating language models into real business workflows. I design multi-agent architectures that process speech, video, and text, combining results into measurable and actionable outputs. My focus is on delivering working solutions fast, prioritizing results over theory.
I design scalable, event-driven, API-first architectures with clear service boundaries. In AWS, I leverage Step Functions, Lambda, DynamoDB, and Batch, while in GCP I implement similar patterns for hybrid workloads. The goal is always reliability, maintainability, and cost efficiency without unnecessary complexity.
I build robust data pipelines for media processing and metadata orchestration, focusing on consistency, retries, idempotency, and observability. I ensure pipelines scale predictably with growing volumes while optimizing for performance and cost.
I ship fast without breaking things. Using Docker, microservices, and CI/CD, I design workflows that balance speed and reliability. Infrastructure as code is applied selectively with Terraform, while observability, logging, and automated testing are built in from the start - not bolted on later.
A pragmatic full-stack approach with a strong backend focus: Python and TypeScript for new systems, with PHP maintained in legacy projects. I design and integrate APIs, webhooks, and external services, applying modern security principles like least privilege, secrets management, and proper authentication flows.
I lead by building, not by presenting slides. I rapidly deliver POCs and MVPs, transforming them into production-ready products. Alongside development, I mentor team members, conduct code reviews, and maintain clear communication with stakeholders to ensure alignment between technical and business goals.
