About
Senior Full-Stack Engineer with 6+ years of experience building and scaling production-grade software across fintech, healthcare, and enterprise data platforms. I specialize in designing reliable backend systems using .NET/C# and React, with hands-on experience in distributed processing, concurrent applications, REST APIs, and microservice architectures.
Throughout my career, I've built services and workflow orchestration systems that automate complex business processes, improve system reliability, and support high-volume data movement. I enjoy solving engineering challenges around scalability, fault tolerance, performance, and maintainability, with a strong focus on writing software that remains dependable in production.
While backend engineering is my primary focus, I'm equally comfortable delivering complete products by building modern web applications with React and Angular and collaborating across the full development lifecycle—from architecture and implementation to deployment and production support.
I'm passionate about software engineering beyond day-to-day development, with a strong interest in distributed systems, system design, operating systems, and production reliability. I continuously invest in deepening my understanding of how large-scale systems are designed, operated, and evolved to build software that is simple, resilient, and built to last.
Selected Projects
PST-extract
2025 - PresentA console application built to explore Microsoft Outlook PST (Personal Storage Table) files at the binary level, converting raw bytes into readable emails, attachments, and files. Instead of relying on existing PST libraries, this project parses raw bytes using only system-level APIs and reconstructs messages by traversing the PST's three logical layers: Node Database (NDB), Lists, Tables, and Properties (LTP), and the Messaging layer.
Work Experience
Senior Software Engineer
- Architected and delivered a distributed data processing platform for PST-to-MSG conversion and MSG ingestion into relational databases, executing workloads in parallel across multiple servers with real-time progress visibility for clients.
- Designed and owned a centralized orchestration layer in which the API dynamically selected target virtual machines, assigned per-VM worker capacity, and remotely executed NFS-hosted executables via PowerShell sessions, enabling controlled, scalable parallel job execution.
- Built a multi-step, high-throughput job pipeline that dynamically generated task-specific execution scripts and executed them using PowerShell runspaces with thread-level parallelism, supporting high volume workloads at scale.
Contracted Full-Stack Engineer (Part-time)
- Integrated MYOB accounting as an external service via a dedicated microservice, implementing asynchronous purchase order and invoice workflows using AWS SQS to ensure reliable, non-blocking synchronization with the core healthcare platform.
- Implemented purchase order cancellation and re-creation workflows, resolving data consistency issues such as duplicate items, incorrect charge sheets, and mismatched reconciliation states across prosthesis management and invoicing modules.
- Added and refined freight and additional fee calculations (including GST) across purchase orders, invoices, PDFs, and Excel exports, ensuring accurate financial reporting and alignment with accounting rules.
Contracted Frontend Engineer (Part-time)
- Developed a core, backend-driven Angular form component as a contracted part-time engineer at AccAlly, enabling organizations to securely integrate third-party systems such as GitHub, Jira etc each with different authentication requirements, into a single access control platform, while also contributing to a small set of supporting UI pages.
Full Stack Engineer
- Contributed to high availability fintech platforms, including e-wallets, payment gateways, and international remittance systems such as Merchantrade Money and eRemit, ensuring secure, real-time financial transactions.
- Implemented OTP-based payment authorization flows and refactored payment integration layer using factory pattern, replacing hardcoded conditional logic for third-party remittance providers and improving code maintainability and scalability.
- Identified and remediated SQL injection vulnerabilities in the Remit back-office application by migrating the query to Entity Framework.
Software Engineer
- Worked on healthcare insurance platforms, handling complex authorization and claims payment logic within a legacy VB.NET web form application.
- Contributed to a browser modernization initiative, migrating legacy applications previously limited to Internet Explorer to modern web browsers.
- Developed a Client Setup Utility Windows Application to integrate five separate Client Setup Utility Windows applications into a single application.
Full Stack Engineer
- Sole developer for a web-based property management system, delivering a full-stack solution with an Angular SPA frontend and ASP.NET Core Web API backend covering accounting, tenant and property management, contract and rent management, and billing.
- Implemented secure access control using JWT-based authentication with dynamic role management, per-page permissions (Read, Read/Write, Update), enabling fine-grained authorization across the application.
- Directly collaborated with clients to gather requirements, translate business needs into application features, and implement end-to-end workflows for property, lease, tenant, and accounting management.
Junior .Net Developer
- Contributed to the development of a CRM platform managing sales, product outlets, and advertising campaigns.
- Built backend APIs and frontend components using ASP.NET and React.
Software Engineer
- Designed and delivered standalone management applications for small businesses, including a Windows Forms and local SQL server based accounting and stock management system for a crusher business, reused and adapted for a restaurant client.
- Developed a hotel booking web application using React for the frontend and Django for the backend.
