Crafting at scale.
A selection of products and architectural decisions I led from concept to delivery.
Privacy infrastructure for modern SaaS for consent, DSAR, and evidence by default.
Designed and building a Next.js-native DPDP/GDPR consent + DSAR platform with tenant by domain isolation, purpose-level gating, and streaming export pipelines backed by tamper-evident audit logging for regulator ready evidence.

Cybersecurity SaaS products built in a fast changing startup environment.
Led end to end frontend delivery for multiple cybersecurity products, translating changing requirements into reliable releases with clean UI architecture, reusable components, and strong collaboration across product, design, and backend teams.
Performance hardening and speed focused refactors for public and dashboard experiences.
Improved production web performance and discoverability by tightening render paths, refining bundle and chunking strategy, and strengthening SEO fundamentals such as metadata, canonical structure, and indexable page delivery for high traffic surfaces.

Experience
A timeline of engineering leadership and product development across high growth startups and enterprise teams.
Senior Full-Stack Engineer & Founder
Building a privacy-first consent and DSAR platform. Implemented domain-based multi-tenant isolation, RBAC-backed flows, hash-chained audit events, and a Redis worker plus S3 streaming pipeline for large encrypted exports. Set up Docker + Vercel CI/CD and authored core product specs for a v1.0 pilot.
Senior Software Tutor (Full-Stack, MERN)
Delivered instructor-led MERN training and mentored students through code reviews, debugging support, and structured feedback on assignments and mini-projects, reinforcing clean coding and web development best practices.
Senior Software Engineer II
Led frontend delivery for threat intelligence and security platforms, collaborating with the CTO for high-stakes demos and shipping the initial CERT-In release. Revamped cyware.com for faster rendering and stability, supported VPAT-driven accessibility remediation, and modernized legacy dashboard code with Vue 3 + Vite using route-level splitting and chunking to reduce initial JS payload.
Software Lead, Web Development
Sole developer for the early-stage web product and marketing site. Built core dashboards and campaign visibility features using AngularJS, Jade, and CoffeeScript, translating founder requirements into production-ready UI under rapid iteration cycles.
UI Developer
Delivered end-to-end client websites from requirements through deployment and maintenance. Provided client support and content updates, and was promoted to lead and train interns for brand promotion and development work.
