Crafting Scalable, Data-Driven & AI-Powered Web Experiences
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 — from UI down through REST API contracts, PostgreSQL, and JWT-based auth.
I've shipped 4 production dashboards in 1.5 weeks, taken a 0→1 EC BOQ module to production in 2 months, and cut UI defects 70% and feature build time 60% by building out a reusable component architecture with Material React Table, TanStack Query, and ECharts.
More recently, I've been working on Net-Zero forecasting systems at Accacia and building RAG/LLM features — including TalentLens AI, an ATS that critiques resumes using LangChain and hybrid retrieval.
What I Bring to the Table
Rapid Product Delivery
- Shipped 4 MVP dashboards in 1.5 weeks at Accacia, enabling real-time carbon tracking across 3+ asset types.
- Built 3 emissions systems in 72-hour sprints with zero production rollbacks.
- Architected EC BOQ system (0→1) with live calculators, editable tables & visualizations in just 2 months.
Performance Engineering
- Achieved 70% reduction in UI defects via ECharts live-update architecture.
- Cut API boilerplate by 40% through TanStack Query integration.
- Standardized data-heavy tables → 60% faster feature delivery.
🌟 Key Differentiators
Ownership & Delivery
- 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%.
Full-Stack Frontend Approach
Beyond UI: experienced in API design (Nest.js), cloud (Azure, AWS), and CI/CD (YAML, SonarQube) with 100% test pass rates.
Applied AI / RAG
Built TalentLens AI, a RAG-based ATS (LangChain + Llama 3.1) that critiques resumes line by line using hybrid retrieval.
🌟 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.
