Bio

Senior fullstack, based in Gatineau.

I work at the intersection of three technical domains: headless e-commerce (PrestaShop, WordPress, Symfony, Next.js + PrestaShop, migrations and custom modules), B2B SaaS platforms and business applications (Node.js, React, TypeScript, NestJS, Meteor.js, Supabase), and web performance combined with applied AI (Core Web Vitals, WCAG accessibility, AI in production via OpenAI and Claude — semantic search, RAG, conversational agents).

Twelve years, no hype-driven leaps. PHP / Symfony since 2015. PrestaShop across all versions. React.js since it became a standard. TypeScript by default since 2022. Applied AI integrated in production on the most recent mandates.

Born Idriss Sergio Talom Nokam, I sign as « Sergio Nokam » in commercial contexts. Born and trained in Cameroon (Master's in Computer Science, Université de Yaoundé 1, 2009). Founder of IziSolutions in Yaoundé since 2018, a web agency serving international clients. Settled in Gatineau (Quebec) since 2025. NOKARIS is the brand dedicated to mid-market North America — productized and bilingual.

Alongside tech, I'm training as a travel counselor in Quebec — not a detour. Kestrelia, my most advanced Lab project, is precisely a flight fare anomaly detection platform. The training feeds the product, the product informs the training.

Languages: native French (FR-CA), professional English (EN-CA — daily use on Anglo-Canadian and US mandates).

What I'm looking for

Three kinds of conversations, three clear no's.

✓ Yes, let's talk

  • NOKARIS mandates

    North American DTC brands $5–50M who want a productized e-commerce engineering atelier: Stack Diagnostic, AI Spark, Hydrogen Migration, Pulse, Embedded.

  • Technical conversations

    Exchanges with CTOs, Heads of Engineering, mid-market founders on headless commerce, applied AI, and performance. No pitch — mutual signal.

  • Speaking and podcasts

    Talks on headless e-commerce, AI in production, web performance. EN-CA and FR-CA. Meet-up, conference or technical podcast formats.

✗ No, this isn't the right channel

  • White-label subcontracting for larger agencies (erodes the brand)
  • Mandates < CAD $2,500 or < 5 days (breaks the Ship in 90 promise)
  • Full-time technical leadership of an internal team (NOKARIS stays solo)
  • WordPress rebuilds without strategic dimension (saturated market)

Education and certifications

Recognized degrees and credentials.
