With about 5 years of experience, I've built React/Next.js products in high-growth startups, extending into Node.js/Nest.js to own features end to end. Most recently, I've been leading full-stack development for Net-Zero forecasting and carbon-reporting systems at Accacia.
What I Bring to the Table
Rapid Product Delivery
- Shipped 4 production dashboards in 1.5 weeks and 3 emissions-tracking systems in 72 hours at Accacia, enabling real-time carbon reporting across 3+ asset types with zero production rollbacks.
- Took the 0→1 EC BOQ module to production in 2 months, with live calculators, editable tables, and visualizations.
Performance Engineering
- Cut UI defects 70% via ECharts live-update architecture.
- Cut API boilerplate by 40% through TanStack Query integration.
- Standardized data-heavy tables → 60% faster feature delivery.
Ownership & Mentorship
- Comfortable owning 0→1 systems end to end and moving fast under pressure — built the CRM platform at Kafqa with 15+ reusable components, cutting future dev time 30%.
- Mentored 2 junior engineers at Accacia, leading code reviews and component standards.
Full-Stack Capability
- Beyond UI: experienced in API design (Nest.js), cloud (Azure, AWS), and CI/CD (YAML, SonarQube) with 100% test pass rates.
How I Work
I care about the outcome a feature drives, not just shipping it. I work closely with design, backend, and product, and I try to hold startup speed and code quality at the same time instead of trading one for the other.
