Crafting digital experiences with precision and purpose
I'm a passionate software engineer with expertise in building modern web applications. With a strong foundation in both frontend and backend technologies, I specialize in creating seamless, user-centric digital experiences.
My approach combines clean code principles with a keen eye for design, ensuring that every project I work on is not only functionally robust but also visually compelling and intuitive to use.
When I'm not coding, you can find me exploring new technologies, contributing to open-source projects, or sharing knowledge with the developer community.
Work Experience
- Integrated Mixpanel analytics across 5+ Atlassian Forge apps (Jira, Confluence), instrumenting event tracking against a product-defined taxonomy within Atlassian's approved analytics domain constraints.
- Built a dashboard translating tracked events into usage and engagement metrics, giving a non-technical product team visibility into feature adoption.
- Migrated a PM2-run production deployment to Docker with CI/CD, stood up a staging environment where only production existed before, and centralized secrets retrieval through AWS Secrets Manager.
- Right-sized EC2 infrastructure based on system load profiling, cutting infrastructure costs by 85–90% with no performance degradation.
- Refactored the legacy codebase into a scalable architecture, remediated CVSS-classified security vulnerabilities, and raised test coverage from 0% to 60%+.
- Shipped real-time multi-user collaboration via WebSockets for a client dashboard, including live presence indicators, cross-entity sync, and field-level concurrent editing resolved through a 3-way merge.
- Built the end-to-end ticketing email system for an Event Management SaaS client, covering three transactional flows (payment confirmed, payment pending, order cancelled) with dynamic attachments: PDF tickets, Apple Wallet passes, and invoices
- Implemented RFC 8058 compliant one-click unsubscribes and iCalendar (.ics) event integration, ensuring deliverability compliance and a native calendar experience for attendees
- Eliminated a cross-organization data exposure vulnerability by enforcing foreign key constraints and RLS-protected database policies, preventing tenant boundary violations across the multi-org platform.
- Improved platform query performance by adding indexes on previously unindexed search and filter columns and implementing server-side prefetching for PostgreSQL filter tables, reducing redundant client round-trips on high-traffic filter tables
- Built a full-stack SaaS advertising platform, connecting advertisers with 300+ streamers using Next.js and Strapi CMS with PostgreSQL, handling campaign management and end-to-end streamer onboarding.
- Architected an automated ad injection pipeline using Trigger.dev to orchestrate campaign delivery across 100+ concurrent live streams simultaneously, eliminating all manual ad placement operations.
- Architected automated ad injection pipeline using Trigger.dev to orchestrate campaign delivery across 100+ concurrent streams, eliminating manual ad placement for every campaign run.
- Cut database CPU load by 60% by introducing Redis caching for high-frequency queries and implemented resilient error-handling strategies to prevent cascading request storms during third-party service outages.
- Diagnosed and resolved a production WebSocket reliability issue using SigNoz observability, restoring reliable alert delivery by implementing sticky sessions for session affinity across scaled pods.
- Built and customized React dashboard modules for pharmaceutical jewelry manufacturer ERP system, including inventory management, HR, order tracking, finance, client management, and analytics interfaces.
- Debugged and resolved critical payment processing vulnerabilities and user interaction defects in the platform's engagement system.
- Integrated SeekMake's quote generation API with CyberMake's 3D modeling platform, enhancing product offerings.
