About Me

Portrait of Shivarajkumar

I'm a Senior Frontend Developer based in Bengaluru, India, with 2.5+ years delivering production-grade web applications and enterprise SaaS platforms. Most recently I spent over two years at Devcansol Pvt Ltd (Chennai) building React, Next.js, and SvelteKit products — and I'm now looking for my next senior frontend role.

My core focus is reusable component architecture, responsive UI, AI integrations, and performance optimisation — complemented by practical Node.js, Supabase, and PostgreSQL experience, so I can carry a feature from data layer to shipped interface alongside cross-functional teams.

I also take on freelance and contract web development projects — particularly for small businesses and retailers looking to establish or upgrade their digital presence. If that's you, let's talk.

  1. Senior Frontend Developer

    Apr 2025 – Aug 2026

    Devcansol Pvt Ltd, Chennai

    ReactSvelteKitTypeScriptJavaScriptSupabaseNeon PostgreSQLUpstash RedisREST APIsPrisma
    • Built the Home Value Estimator — an AI-powered, subscription-gated property analysis tool delivering rent vs. sale comparisons, market estimates, sale market comparables, and AI-generated insights across interactive charts and visual reports.
    • Minimised paid API spend on that tool with Upstash Redis rate limiting (account-based and anonymous) plus 90-day address caching, and served shareable reports from Neon PostgreSQL via unique ID-based URLs for client distribution.
    • Contributed core DCS/Ripple SaaS platform features — Rent Insights, CRM, a productivity suite (task assignment, employee activity tracking), website analytics via Google Search Console, and contact and lead management — all subscription-gated under a role-based multi-tenant auth system with per-client data isolation.
    • Contributed to the PMA → DCS/Ripple frontend migration, handling component restructuring and content rework, then onboarded and customised 10+ client websites onto the unified platform while maintaining complete system stability.
    • Built Referral Pages end-to-end — submit-referral form, earnings calculator, and referral lead type — with dynamic team, FAQ, and feature templates configurable per tenant, owner, and vendor role.
    • Delivered UI/UX upgrades across property management client platforms including a standout navigation redesign shipped to production, and built trailique.ai plus production sites for conference organisers and event management clients — modernising content with SEO-first copy and improving Lighthouse scores.
    • Designed and developed z-score.org, a financial services site for US bookkeeping and fractional CFO services, end-to-end in 15 days under CEO direction; built the S-Corp Calculator for yourblueskies.com with Calendly integration that auto-populates user data and captures leads across every CTA touchpoint.
    • Contracted to Vursu (US-based AI SaaS) for a month — onboarded directly to their Knowledge Operating System codebase and delivered folder-functionality rework, feature testing, and cross-device responsiveness.
    • Diagnosed and fixed a 100–800ms latency bottleneck in a high-traffic lead form by moving validation server-side, removing a redundant network round-trip.
