Enterprise CRM platform for workflow automation, reporting, access control, and internal business operations.

• Defined a shared authorization model for three user types with granular and multi-role permissions, keeping UI visibility, API access, and backend validation aligned as new workflows were introduced.

• Structured React features and NestJS domains around business workflows so changes to reporting, administration, or access control could remain isolated instead of affecting unrelated parts of the CRM.

• Reworked performance-sensitive React flows by reducing unnecessary state propagation, isolating expensive renders, and splitting application code to keep data-heavy CRM screens responsive as state complexity grew.

• Designed real-time synchronization for changes originating outside the active client, keeping dashboards and workflows aligned with server state without relying on manual refresh.

Stack: React, Next.js, TypeScript, NestJS, Redux Toolkit, PostgreSQL, REST APIs, Socket.io, Docker, Google Cloud

• Structured state across social, wallet, transaction, and analytics domains so independent asynchronous APIs could update related data without leaving the client in inconsistent states.

• Separated API interaction, state transitions, and presentation logic, allowing new product flows to reuse established behavior instead of increasing coupling between screens.

• Integrated reward flows connecting user activity with platform currency and cryptocurrency wallet operations while keeping financial and UI state synchronized.

Stack: React, Vite, TypeScript, Redux Toolkit, React Router, SASS, Formik, Magic SDK, Recharts, REST APIs

• Modernized a legacy React 15 production application incrementally, introducing newer React and TypeScript patterns without requiring a disruptive full rewrite.

• Increased TypeScript coverage and added Cypress protection around migrated flows, catching contract and interaction regressions while legacy and newer modules continued to coexist.

• Unified device automation behind a Trigger > Conditions > Action model and used WebSocket synchronization for device state that could change independently of the active browser session.

Stack: React, TypeScript, Redux, Material UI, Cypress, WebSockets, Socket.io, REST APIs

• Extended CRM authorization to four access levels with multi-role accounts, keeping permissions consistent across navigation, UI actions, APIs, and financial workflows.

• Built financial dashboards, reporting, and large-file upload flows up to 1 GB with dedicated handling for progress, long-running operations, and failure states.

• Expanded into Node.js/TypeScript backend development for posts, short-form video, chat, relationships, and content interactions backed by PostgreSQL and Sequelize.

Stack: React, Node.js, TypeScript, Redux, Redux Saga, Feathers.js, PostgreSQL, Sequelize, Docker, Google Cloud

Built reusable React and Redux patterns across commercial products, replacing repeated screenlevel implementations with shared component and state behavior. • Delivered REST-integrated responsive interfaces across multiple products, establishing the frontend foundation for later work in complex state, real-time systems, performance, and fullstack architecture. Stack: React, JavaScript, Redux, React Router, Material UI, Redux Saga, MongoDB
