💻 Building robust, scalable, and secure backend architectures with production-grade business logic.

⚡ I am a backend-focused Software Engineer specializing in building scalable enterprise systems, transactional workflows, and distributed microservices. I design robust backend architectures, secure REST APIs, and automated data pipelines using Java / Spring Boot and Node.js.

🛡️ Experienced in implementing enterprise-grade security (RBAC, JWT), event-driven microservices (Kafka), high-performance caching (Redis), and containerized deployments (Docker, CI/CD, Azure). Backed by a strong algorithmic foundation with 600+ DSA problems solved in Java.

Enterprise Accounting & Financial Systems | Node.js • Express • PostgreSQL • Docker • Azure

• ⚡ Bulk Data Pipelines: Engineered a robust, transactional Excel bulk upload pipeline featuring asynchronous parsing, schema validation, and preview-before-commit capabilities, drastically reducing incorrect database writes.
• 💸 Financial Workflows: Designed and implemented critical modules for an enterprise accounting suite, including Purchase Order (PO) management, Multi-Item Ledger transactions, and Bank Reconciliation matching logic.
• 🛡️ Compliance & Taxation: Programmed complex GST and HSN-based tax calculation engines supporting multi-tiered and multi-regional taxation rules.
• 🔐 Security & Auth: Configured secure API routes using Role-Based Access Control (RBAC) and JWT validation for distinct organizational profiles.
• 🐳 Infrastructure & CI/CD: Maintained Docker container deployments and collaborated on CI/CD workflows using GitHub Actions targetting Microsoft Azure.

Worked extensively on enterprise private repositories during professional experience (2025–2026).

💼 Contributions include enterprise backend development, accounting systems, invoice processing, GST workflows, RBAC systems, reconciliation modules, and production-grade REST APIs.

• 🩺 Core Engine: Engineered a secure medical platform supporting RBAC (Admin, Doctor, Patient flows) and OTP-based authentication.
• 💬 Real-time Comms: Developed real-time clinic communication channels and doctor-patient chat using Socket.io.
• ☁️ Secure Media: Integrated secure Cloudinary media upload pipelines with server-side payload validation.

• 🔄 Matching Algorithm: Designed an automated reconciliation engine that matches bank statements against ledgers based on multi-parameter fuzzy logic.
• ⚡ Performance Tuning: Implemented Redis caching for high-frequency financial lookups, improving transaction verification speeds by 60%.
• 📝 Audit Trail: Built detailed audit logs and transaction history reporting utilizing event-driven updates.

• 🪙 Rate Limiting & SaaS Flow: Developed a full-stack dashboard utilizing text-to-image AI generations with built-in credit validation.
• ⚡ Cache Management: Used Redis to optimize API call rates and store active session states.

🧠 DSA Mastery: Solved 600+ problems across LeetCode and GeeksforGeeks using Java.

Proficient in Trees, Graphs, HashTables, Tries, Dynamic Programming, Greedy, and time/space complexity optimization.
