Selected work

A few projects with the reasoning behind them: what the problem was, what I built, and what changed afterwards.

Personal · 2026

A freelance site rebuilt on Next.js so every page is server-rendered, shareable, and findable.

Next.jsReact 19TypeScriptTailwind CSS v4Vercel

The problem

The original version was a single-page React app rendered entirely in the browser. Search engines saw an empty shell, links shared on social media showed no preview, and there was no way to add pages for individual pieces of work. It described who I was, but gave a prospective client nothing to evaluate.

What I did

  • Rebuilt on the Next.js App Router so pages are pre-rendered as static HTML. The content lives in the source, not assembled by JavaScript after load.
  • Added per-page metadata and generated Open Graph cards, so every case study has its own title, description and social preview image.
  • Moved the contact form to a server route, which keeps the API key out of the browser bundle and adds validation and rate limiting.
  • Restructured the content around what a client needs to decide: what I build, what it costs, what shipped before.

The result

  • Every page is static HTML, served from the edge.
  • Case studies are individually shareable with correct titles and preview cards.
  • No credentials in the client bundle.

SaaS product · 2025

A trading journal and chart-analysis platform where traders log trades, review setups, and run analytics on their own performance.

Next.jsTypeScriptSupabaseStripePostHogTailwind CSS

The problem

Traders tracking their own performance across spreadsheets and screenshots have no single place to log trades, see real analytics on what's actually working, or come back to a chart setup later. Lessons from past trades quietly get lost as a result.

What I did

  • Built a trade journal with 30+ fields, custom fields, image attachments and per-trade ratings on Supabase Postgres, with row-level security ensuring every user only ever sees their own data.
  • Built "Setup Lab", an interactive charting tool (13 indicators, drawing tools, saved colour templates) so traders can save chart setups and link them back to real trades.
  • Added analytics (win rate, P&L, holding period, custom-field breakdowns), CSV bulk import for existing trade history, and slideshow-style trade review templates.
  • Wired up tiered Stripe subscriptions, PostHog analytics on key funnel events, and Resend for transactional email.

The result

  • A single platform covering journaling, chart analysis and analytics that previously lived across spreadsheets and screenshots.
  • Tiered subscriptions and a referral program running end to end, from signup through to billing.

Personal project · 2025

A private, vouch-based matchmaking platform with an invite flow, a consent step, a questionnaire, and admin-run pairing.

Next.jsTypeScriptSupabaseStripeResendZod

The problem

Private matchmaking needs a trust layer a generic sign-up form can't provide. People need to be vouched for by someone the platform already trusts before they're let in, and every step of that chain needs to be auditable.

What I did

  • Modelled the trust chain as data: a public vouch form, a consent step for the vouched person, an invite-gated private questionnaire, and an admin review workflow, each backed by its own Supabase table.
  • Locked access down with Row Level Security set to insert-only for anonymous users on public forms, with every admin action running server-side under the service role key.
  • Built the admin dashboard covering the full pipeline, from vouches to consent to profiles to matching, plus a notification log auditing every email sent through Resend.
  • Added Stripe for paid membership and react-hook-form + zod for validated multi-step forms.

The result

  • A working vouch-to-match pipeline running end to end: public form, consent, private questionnaire, admin review and pairing.
  • The trust chain the product depends on is enforced at the database level via RLS, not just in the UI.

About me

I'm a web developer based in Limassol, Cyprus. I build websites and web applications for small businesses and startups. Often one person handling design, frontend, backend and deployment is just faster and cheaper than putting together a whole team.

I studied Computing Science at the University of Groningen, graduating in 2025. Alongside my final year, I worked at AirHub for a year and a half, shipping features across a Vue and TypeScript stack and writing the automated tests that kept releases safe. Balancing a full-time job with a degree taught me the part that matters most for client work: shipping something solid on a deadline beats shipping something perfect eventually.

I care about the unglamorous things. Pages that load fast on a phone with two bars, forms that actually reach your inbox, code your next developer can read. Those are what keep a site working long after I hand it over.
