Experience
Deloitte Digital
Current Employer- Led architecture and delivery of a utility service portal serving 10–16K daily visits and 1M+ customer records across multiple US states, supporting residential and large commercial billing workflows.
- Drove end-to-end modernisation initiatives including Angular 5 → 10 migration, Azure AD B2C UI refactor from monolithic jQuery to MVC + TypeScript, and re-architecture of a legacy notification settings page into a modular Angular SPA - designed to serve 3 sub-companies from a single codebase with smart data handling.
- Improved Google Lighthouse performance scores from 75 to 98–99 on a brownfield application through targeted rendering, asset, and interaction optimisations.
- Reduced a critical registration endpoint response time from 30s to 10s by refactoring database queries and introducing async queues for parallel downstream service calls.
- Identified and resolved security vulnerabilities on anonymous and authenticated endpoints during active development - proposed and implemented fixes that were adopted over the SecOps team's own recommendations after review.
- Oversaw system design reviews, coding standards, deployment strategy, and CI/CD adoption across teams - maintaining technical direction without becoming a bottleneck to delivery.
- Drove cross-functional delivery across 15+ stakeholders - developers, QA, UX, analytics, product, and business leads - in a fully remote enterprise engagement; sole technical decision-maker day-to-day with architect engaged for approvals only.
- Mentored and managed teams of 3–5 junior engineers across enterprise projects - maintained near-zero production defect record across bi-monthly release cadences through code standards, CI/CD adoption, and rigorous handoff documentation.
- Challenged design proposals before development - flagged a UX decision that was overruled at demo stage by business leadership three months later, validating early pushback as a standard practice.
- Drove engineering accountability through planning rigour, stable release cadence, and clear communication of technical tradeoffs to non-technical stakeholders.
- Built internal tooling to reduce team friction - including a QA test utility that eliminated 25-minute manual timeout waits, environment-switching scripts for dev and test teams, and an authentication configuration visualiser.

realprint
- Designed and built the entire customer-facing platform solo from scratch - an end-to-end ordering system where customers could upload STL files, preview 3D models in the browser with material visualization, configure post-processing options, and check out.
- Implemented real-time 3D model rendering using Three.js - first time working in 3D space - navigating coordinate systems, point scaling, and material shading from scratch without prior experience in WebGL/3D rendering pipelines.
- Built backend file handling, order tracking, and automated customer communication on Node.js, making deliberate technology choices (Node + jQuery) to maximize shipping speed over architectural elegance - launched in under 8 months.
- Operated in a zero-salary, high-pressure environment for 6+ months, shipping a production system while learning that time-to-field matters more than stack cleanliness - a principle that still informs technical decision-making.
- Secured and delivered B2B contracts, including a precision helical connector piece iterated across 7 prototypes in 2 weeks for a manufacturing client - a turnaround conventionally impossible without costly tooling changes.

Vyay (Sanskrit: "expense") is a privacy-first expense management Android app built for modern phones. No data leaves the device - all analysis and summaries are computed locally. Vyay parses transaction SMS/notifications to extract amounts, dates, and merchant info, while also supporting manual entries, custom categorization, and insightful spending summaries.
- 🔒 Privacy-first: all processing & storage remain on the user's phone
- 🔍 SMS transaction parsing with robust pattern matching and categorization
- 📈 Local summaries and reports, with manual edit and tagging support
