Work Experience

Software Development Engineer

Indarka Energy Private Limited — Arka360 Platform

Aug 2022 - Apr 2026

Engineered the end-to-end Proposal Workflow system — Arka360's flagship feature — enabling solar installers to generate comprehensive 20–25 page downloadable PDF proposals containing customer information, solar design data, pricing models, financial projections, and project details; built dynamic multi-step UI, real-time form validation, and automated PDF report generation using React.js, TypeScript, and Redux Toolkit. Architected the Solar Calculator system — the platform's primary estimation engine — with complex business logic, real-time energy calculation workflows, and automated report generation, serving as a core tool for 4,000+ global installers. Built key product modules using React.js, Redux Toolkit, and Zustand: Pricing & financing systems for solar cost calculations, Design defaults & project configuration workflows, Organization & inventory management features, Consumption and data-driven calculation logic. Spearheaded UI/UX revamp across major platform modules — translated Figma designs into pixel-accurate, responsive, cross-browser compatible interfaces using Tailwind CSS and Shadcn/UI, significantly improving usability for global installer workflows. Delivered ArkaGo (React Native) cross-platform mobile app contributions including Organization Management screens, Lead Management workflows (lead creation & detail pages), REST API integrations, and i18n/localization for multi-language support — app has 1K+ downloads on Play Store & App Store. Optimized frontend performance through lazy loading, code splitting, memoization (useMemo, useCallback), and API call reduction — delivering faster load times and smoother UX across the platform. Built robust REST API integrations using Axios and React Query — implemented loading states, error boundaries, optimistic updates, and async data flow management across all platform modules. Wrote unit and component tests using Jest and React Testing Library; reduced production bugs through rigorous edge-case handling and code review practices. Collaborated with cross-functional Agile/Scrum teams of 4–6 frontend engineers; participated in sprint planning, code reviews, and iterative product delivery cycles. Leveraged AI-assisted development tools (ChatGPT, Claude, Windsurf, GitHub Copilot) to accelerate feature delivery, improve debugging efficiency, and maintain high code quality.
