- Built a geospatial field monitoring system on Mapbox GL processing satellite imagery into NDVI, NDMI, MSAVI and NDRE raster overlays with historical playback and per-pixel insights. - Designed an end-to-end RBAC system modelling 4 user roles across 2 subscription tiers with permission gates at route, component and API level. - Built a GDD-driven phenological calendar with live forecasting and a metrics dashboard featuring custom heatmaps and time-series visualisations.

- Sole-engineered a full-stack Instagram DM automation SaaS on the Meta Graph API with keyword-triggered automations across posts, stories, and inbox flows. - Built a custom analytics pipeline without third-party SDKs, featuring cookie-based tracking, MaxMind GeoLite2 geolocation, ua-parser-js device detection, time-series analytics, and interactive maps. - Designed automated webhook subscription management and a cron system that extends active automations to future posts, enabling reliable scaling.

- Built the complete product documentation site from scratch covering installation, features, integrations and keyboard shortcuts across multiple structured sections. - Diagnosed and partially resolved a critical audio segregation bug in the Electron desktop app, separating microphone input from system audio output to prevent voice overlap during headphone-free meetings.

- Built an OpenAI-powered pipeline that extracted, categorised and severity-classified raw pentest findings, generated professional PDFs via Puppeteer from custom HTML templates and synced reports and structured findings to Vanta. - Integrated Jira and Slack via webhooks to auto-create severity-based tickets and notify clients on new findings.
