• Developed the core of the salary calculation engine for FleetHours NextGen, a distributed .NET/MongoDB backend computing driver payroll for European transport operators: 20 salary rules (leave accrual, overtime banking, weekend premiums, expense reimbursements) and the pipeline that executes them in dependency order, configured per customer. • Built the Calculation Management service: fair-share batching of payroll runs via Quartz scheduling and Kafka event-driven state tracking — no customer's run can starve another's — with safe cancellation of thousand-employee runs. • Created a version-pinned regression harness that captures real calculation runs and replays them offline through the actual engine, catching pay-affecting regressions before every release. • Fixed high-impact correctness bugs: silent decimal corruption zeroing allowance parameters, a deep-clone defect mutating historical payroll configuration, and double-paid overtime hours. • Drove platform work across 40 repositories: semantic-release versioning adopted into the organisation-wide C# template, the .NET 10 migration, container security upgrades, and test coverage raised above 80% for five services — 355+ peer-reviewed pull requests merged across both roles.

• Built the backend activity data platform: resumable, watermark-based ingestion scaled to 600K activities per customer, Activity CRUD with a complete audit trail, activity splitting/merging, and Correction APIs — part of 12 microservices built from scratch across the product. • Hardened the shared libraries inherited by every service: PATCH support distinguishing absent from null, generic referential-integrity checks on delete, and exception middleware returning correct HTTP status codes. • Started at Trimble's SketchUp division: shipped the SketchUp Diffusion generative-AI extension and contributed to SketchUp Viewer's first Meta Quest release, before moving to the transport division in May 2024. • The transport division, including my team, was acquired by Platform Science in Feb 2025 - employment is continuous.

• Contributed to the development of Posh Shows, a live-streaming feature that allows users/sellers to curate and showcase their favourite listings. • Optimised performance by reducing response load time by 30% across all domains, with a primary focus on the UK domain, resulting in improved performance and a 15% increase in user engagement. • Implemented logic to limit user listings to a curator show and set a maximum limit for total submissions to a show, enhancing the Posh Shows experience. • Streamlined the process of updating tag lists by introducing a feature setting from CSV, making it more convenient to use.

Software Engineer II at Platform Science | M.Tech | Building the payroll backend for European transport

About

I build the backend of FleetHours NextGen, a payroll platform for European transport operators — a distributed .NET/MongoDB system that turns raw driver activity into salary. My work spans the salary calculation engine (20 configurable salary rules and the pipeline that executes them in dependency order), the Calculation Management service (Quartz scheduling and Kafka event-driven state tracking with fair-share batching across customers), and a version-pinned regression harness that replays real calculation runs offline to catch pay-affecting regressions before release. Across both roles: 355+ merged pull requests, 12 microservices built from scratch, activity ingestion scaled to 600K activities per customer, and test coverage raised above 80% on five services. I also contribute to the Angular frontend and drove semantic-release versioning into the organisation-wide C# template across a 40-repository estate. Published a blockchain payments paper at IEEE TrustCom 2023. B.Tech and M.Tech (Dual Degree) in CSE from IIITDM Kancheepuram, CGPA 8.75/10.
