Configured and deployed Microsoft's Carbon Emissions Tracking solution for a client looking to measure, monitor, and report on their organization's environmental footprint. The setup involved connecting the client's Microsoft 365 environment to the Microsoft Cloud for Sustainability, mapping energy and emissions data sources, and configuring dashboards that gave stakeholders clear, real-time visibility into carbon output across operations. Data ingestion pipelines were set up to pull from relevant business systems, ensuring emissions calculations were based on actual operational data rather than estimates. Reporting templates were configured to align with common sustainability disclosure frameworks, giving the client audit-ready outputs they could use for internal reporting and external stakeholder communications. The result was a functional, integrated carbon tracking system that turned a complex compliance requirement into a manageable, data-driven process.

Developed a floating WebView overlay feature for HorizonOS, allowing users to access web content in a persistent, resizable window that sits on top of other applications without interrupting their workflow. The overlay was built to be lightweight and responsive, launching quickly and rendering web pages cleanly within a floating frame that users could reposition and resize freely across the screen. Special attention was given to how the overlay interacted with the underlying OS environment — ensuring smooth layering, proper focus handling, and clean dismiss behavior. The feature was integrated natively into the HorizonOS shell, following the platform's existing design language and interaction patterns so it felt like a natural extension of the operating system rather than an afterthought.

Handled end-to-end tax filing and compliance support for an early-stage startup, navigating the often confusing intersection of new business registration, tax obligations, and regulatory requirements that founders typically encounter in their first years of operation. The work covered identifying the correct tax filing requirements based on the startup's business structure and jurisdiction, preparing and organizing the necessary financial documents, and ensuring all filings were submitted accurately and on time to avoid penalties. Compliance gaps were identified and addressed proactively — including missed registrations, incorrect categorizations, and overlooked deductions that were legitimately available to the business. The founder was guided through each step with clear explanations, so they understood their obligations going forward rather than remaining dependent on outside help for every filing cycle. The result was a clean, compliant tax position the startup could build on confi

Stabilized a Python-based trading system's websocket deployment that was suffering from intermittent disconnections, data lag, and reliability issues affecting live trading operations. The work involved diagnosing the root causes behind dropped connections and message delays, then rebuilding the websocket handling logic with proper reconnection strategies, heartbeat monitoring, and error recovery mechanisms. Threading and asynchronous processing were optimized to ensure real-time market data was received, processed, and acted upon without bottlenecks or memory leaks under high-frequency conditions. Logging and alerting were improved to give the client immediate visibility into connection health going forward. The result was a stable, production-grade websocket connection capable of handling live trading data reliably without the downtime that was previously disrupting trading activity.

Architected and built a custom Shopify application from the ground up, designed to extend Shopify's native functionality and solve a specific business problem the client's existing store setup couldn't handle out of the box. The project was approached at an architectural level — meaning decisions around data structure, API design, authentication, and scalability were made deliberately from the start rather than retrofitted later. The app was built using Shopify's App Bridge and REST/GraphQL Admin APIs, with a robust backend handling business logic, webhook processing, and data synchronization with the store in real time. The frontend was developed to integrate seamlessly within the Shopify admin experience, feeling native to the platform while delivering functionality well beyond what standard apps offer. The finished application was submitted and approved through Shopify's review process, ready for deployment on the client's live store.
