Core Skills

  • Languages: TypeScript, JavaScript (ES6+), Python
  • Frontend: React, Next.js, SPA architecture, accessibility (ARIA, semantic HTML)
  • Data & APIs: GraphQL, Apollo Client, REST, schema collaboration, typed code generation
  • Systems & Architecture: client-server orchestration, normalized data graphs, caching strategies
  • Performance: large-dataset rendering, query optimization, batching, profiling
  • Testing & Quality: Jest, React Testing Library, Cypress, CI/CD, code reviews
  • AI: browser/on-device LLMs, RAG, agents, prompt design (AI Ambassador at dv01)

Lightning.ai — Frontend Engineer (May 2026 – Present)

  • Building full-stack AI systems end to end — from the model-facing backend to the user-facing frontend, primarily in TypeScript and React.

dv01 (Fitch Solutions) — Senior Frontend Engineer / Technical Lead (Jan 2022 – Feb 2026)

  • Led multi-quarter frontend architecture initiatives for an enterprise financial analytics platform serving institutional clients.
  • Designed scalable client-server data-orchestration patterns that prevent NxM query amplification and keep performance predictable under large dataset fan-out.
  • Modeled large hierarchical financial datasets (100k+ records) with normalized client-side data graphs for O(1) access and predictable rendering.
  • Cut critical page-load time 68% (3.5s → 1.1s) through architectural refactoring, data-fetch orchestration, and render-path optimization.
  • Implemented multi-layer caching that reduced network requests from 13 to 2 per interaction.
  • Introduced typed GraphQL code generation, strengthening API contracts and reducing production defects.
  • Led technical design reviews and mentored junior and mid-level engineers into promotions; helped shape the hiring process to extract quality candidates.
  • Selected as Product Engineering AI Ambassador. Served week-long PEOD (Product Engineer On Duty) rotations, solving novel urgent bugs and time-sensitive customer requests — often delivering fixes within 24 hours.

breathing.ai — Frontend Engineer (2021 – 2022)

  • Partnered directly with the CEO on early product architecture and shipped experimental user-facing experiences.
  • Built a React + TypeScript Chrome extension with ML-driven biodata feedback: live webcam video streamed to AWS, processed by a machine-learning Lambda over S3, returning the user's breathing rate and heart rate.
  • Designed a data layer wired to Google Analytics and Google Tag Manager; led the team on analytics configuration and completed a GTM course.
  • Hired, mentored, and led engineers and international contractors.

Freelance Web Developer / Consultant (2018 – 2022)

  • Built responsive web apps in JavaScript, WordPress, and React; advised founders on scalable frontend architecture.
  • Consulted for a government organization building a React/TypeScript web app — not legally allowed to touch the code, so taught staff over video calls and helped them build and deploy a feature themselves.
  • Consulted startups on React and TypeScript best practices, improving maintainability and performance; also partnered with a designer/WordPress specialist while focusing on custom components and standout projects.

Military Service — Greek Special Forces, Commando Paratrooper (2014 – 2015)

Staz served as a Commando Paratrooper (and Paratrooper Sniper) in the Greek Special Forces, the elite unit of the Greek army.

  • Led troops through physical and weapons training to become elite soldiers and carried out missions.
  • Received a first-class award during radio-communications training.
  • Trained side-by-side with elite soldiers, developing mental and physical toughness and problem-solving under pressure.

Education

  • BSc Computer Science — University of Hertfordshire (2011 – 2014)
  • MIT Certificate — "Artificial Intelligence: Implications for Business Strategy" (2018)
  • Computer Science Intern — Athens Macedonian News Agency (APE-MPE) (2013 – 2014): supported internal enterprise systems and infrastructure for national news distribution; trained on company software and helped train staff.

Interests

Distributed systems, blockchain infrastructure, developer tooling, and data-intensive UI architectures.
