Career history

Senior Software Engineer EY - Technology Consulting

I serve as a Senior Software Engineer, promoted from Level 1 to Level 3, delivering full-stack AI platforms, cloud infrastructure, and technical leadership for government, banking, insurance, and internal consulting initiatives. I lead teams of up to five people and work with stakeholders from requirements gathering through production delivery.

I architected an AI code generation platform for the Saudi Arabia Government using FastAPI, React, and Oracle Cloud. The platform generates development artifacts including data models, SQL, and OpenAPI specifications, reducing new-project delivery from months to days.

I built Claude-based multi-agent delivery acceleration capabilities, designed agent orchestration and validation flows, and reduced targeted digital-service delivery effort from 250 hours to 40 hours. I also lead AI platforms and tooling initiatives, AI asset cataloguing, model-selection guidance, token-cost controls, adoption telemetry, and budget observability.

For a leading Cyprus bank and the Cyprus Government, I delivered RAG assistants, AI strategy and roadmaps, KYC and invoice automation prototypes, and a production public-service assistant supporting more than 1,000 simultaneous users. I also built deployment tooling for a UK insurance company using React, Kubernetes Dashboard APIs, Jenkins CI/CD, Amazon S3, and Okta SSO, reducing deployment time by 80%.

Full-Stack Software Engineer KIOS Research Centre of Excellence

I worked as a Full-Stack Software Engineer, including my internship period, on an EU-funded civil-protection web mapping platform.

I designed and delivered the end-to-end system architecture, developing the backend with Python and Django and the frontend with JavaScript. I built MySQL databases, REST APIs, and Dockerized deployments.

I also developed real-time analytics capabilities using FIWARE, Python, and Power BI to support operational insights for the platform.

Technical Lead & Full-Stack AI Engineer CalliLabs

I lead the ground-up design and implementation of a production AI interview platform for million-subscriber YouTube channels. I work directly with the CEO of a production company serving Netflix and Hulu.

I built configurable episode setup, candidate applications, partner invitations, and solo and group interview workflows. The real-time interview experience integrates Claude, AssemblyAI, and ElevenLabs, while Gemini evaluates recorded video against casting criteria.

I deployed the solution using Next.js, FastAPI, and PostgreSQL on Amazon ECS, RDS, and S3 with privacy controls. I also built a YouTube data collection and analytics platform with Google OAuth, encrypted tokens, quota controls, resumable background jobs, containerized services, and automated ECS deployments.

Technical Lead & Full-Stack AI Engineer LYDS

I delivered a production AI-powered scientific reporting platform for an Amsterdam biotechnology company. The solution automates regulated drug scientific study reports and reduced manual report creation time by 70%.

I integrated LabVantage worksheets and external laboratory reports into an Azure OpenAI workflow that extracts and structures key study information. I designed traceable review workflows so scientists could validate source evidence before report generation.

I deployed the application on Azure with secure access controls and document storage.

Freelance Full-Stack & AI Engineer Upwork

I completed 15 freelance contracts with a 100% job success score and a 5.0 rating while working alongside full-time commitments. I scoped and priced short, self-contained projects directly with clients.

My work covered full-stack web applications, browser extensions, data collection pipelines, cloud-hosted tools, and mobile integrations. I replaced a Google Sheets analysis workflow with a secure web application including restricted login access, setup documentation, and full source-code handover.

I also built an Android application that streamed DJI drone telemetry through WebSockets and live H.264 video via the DJI Mobile SDK. The system used a Django frontend to render live drone positions in 3D with Mapbox GL JS and Deck.gl.
