Where I've shipped, what I built, and how it went.

Co-Founder & Backend Engineer

• >Co-founded Taply and built the entire backend on Django 5.1 and DRF. Eleven section types, four layout variants, drag-and-drop ordering, live theme customization, and version history with rollback.
• >Shipped the NFC and QR sharing layer. Tap or scan opens a user's live profile in under 100ms via Redis-cached loads, with one-tap vCard save that works on both iOS and Android without downloads.
• >Built the real-time analytics engine that tracks profile views, NFC taps, QR scans, and vCard saves, plus a leads inbox that captures visitor contact requests.
• >Delivered the team management console with role-based branding, bulk CSV onboarding, and per-rep analytics. The console closed Taply's first paying enterprise customer, a 250-rep sales org.
• >Integrated Stripe Checkout, Portal, and Webhooks for billing across Free, Pro, Business, and Enterprise tiers. Webhook idempotency is critical because Stripe retries on any 5xx.

Software Engineer

• >Led sprint planning and PR review for a 9-person engineering team. Introduced mandatory CI gates (lint, typecheck, tests) so every PR had to clear them before review.
• >Rebuilt the login system on OAuth2, JWT, and RBAC, closing authentication vulnerabilities in the legacy session-based flow. Ran old and new auth in parallel for a month to migrate without breaking active sessions.
• >Redesigned composite indexes and rewrote ORM queries across a multi-vendor MySQL system. Cut query execution time by 17% across 50+ store deployments, with tail latency dropping more.
• >Migrated idle AWS resources to reserved instances and auto-scaling capacity. Rebuilt CI/CD on CodePipeline and Docker. Cut cloud spend by 35% and deployment lead time from hours to minutes.

Software Developer · including 2.5 months parttime

• >Performance: Owned bottleneck diagnosis and resolution through indexing and queryset optimization, driving measurable reductions in API response times across client applications.
• >API Design: Architected and owned production-ready REST APIs with DRF, enforcing secure auth patterns and optimized serialization logic for low-latency data delivery.
• >Async Architecture: Designed and owned Celery and Redis pipelines to offload reporting workflows and background processing tasks, directly improving frontend responsiveness.
• >Backend Engineering: Designed relational schemas and Django services built for data integrity and scalability across web and mobile surfaces.

Software Engineer Intern

• >Search Optimization: Improved platform search efficiency, lifting user search success rates by 15%.
• >Real-Time Communication: Added real-time in-app chat over WebSocket, lifting user engagement and retention by 30%.
• >API Performance: Optimized 22% of patient dashboard APIs, cutting database queries and reducing response times by 1 second.
• >Doctor Dashboard: Built the doctor dashboard and analytics surface, improving data access by 20% and data-driven decisions by 15%.
