Backend & DevOps for a US-based F&B retail chain

Software Engineer II, Jul 2025 - Present (a year)

• Working on multiple concurrent systems powering restaurant/store operations including mobile ordering, kitchen operations, and in-store digital signage for a US-based F&B retail chain.
• Among the engineers who designed and architected backend APIs, AWS infrastructure, and serverless systems from the ground up.
• Own infrastructure and DevOps across AWS Lambda, API Gateway, Terraform IaC, authentication, DNS, email infrastructure, security, and operational cost management.
• Performed load/stress testing and optimized backend API flows for sub-second p90 latency under production traffic.
• Fine-tuned Lambda runtime and infrastructure configuration to balance latency and cost efficiency (~$200/month per environment handling 10K MAU).
• Implemented RBAC, phone-number authentication, and large-scale webhook ingestion pipelines for Square and DoorDash using queue-driven event processing.
• Built a real-time Kitchen Display System using AWS IoT Core with MQTT/WebSocket-based communication and event-driven serverless architecture; shipped the full system within 3 weeks by leveraging AI-assisted development workflows.
• Developed Android TV software for scheduled campaigns, menus, and promotional media across franchise store locations; optimized for low-resource TV hardware using disk-cached HD video playback, push-driven scheduling, and coroutine-based background execution; delivered end-to-end within 2 months.

Sole engineer on end-to-end product builds (Chrome extension & Aztec wallet)

Software Engineer I, Jul 2023 - Jun 2025 (2 years)

• Led two back-to-back products end-to-end as the sole engineer — architecting, building, deploying, and QA-ing complete systems from scratch.

• Built Stripe-powered billing/subscription workflows and authentication federation using OAuth 2.0 and OpenID Connect.
• Architected and developed a production-ready privacy-focused browser wallet and DApp for Aztec Network, an Ethereum Layer 2 focused on programmable privacy using zero-knowledge proofs.
• Implemented secure cryptographic flows, transaction signing, and key-management systems for privacy-preserving smart contracts.
• Designed state-machine driven UI systems handling complex asynchronous wallet and blockchain interaction flows.

Data engineering for a sleep-tech wearable device

Associate Software Engineer, Jul 2022 - Jun 2023 (a year)

Data engineering for a sleep-tech wearable device used by 100K+ users in the US market.

• Built a data pipeline from scratch in AWS Glue using PySpark, processing tens of GBs of time-series sensor data daily from a health-monitoring wearable device deployed to 100K+ users.
• Optimized pipeline runtime from 3 hours down to 15 minutes through streaming data from S3, intelligent partitioning, optimized joins, and Glue memory/DPU tuning.
• Developed an interactive data dashboard reducing cross-functional team troubleshooting time by 80%.
• Conducted quarterly statistical analysis on user behavior patterns across 10K+ user samples for product insights.
• Ramped up on Apache Spark from the ground up to achieve full technical competence within the first few months on the job.
