Jonny Wu

Senior software engineer and founder with a track record of building and shipping production systems across the full stack - from embedded firmware and distributed backend architecture to AI driven data pipelines. Known for taking end-to-end ownership of complex problems and delivering reliable, high quality software in fast moving environments.

Founder & CTO at Yume Arcade (2023-11 – Present)

Founded and led all technical development for a physical arcade business, scaling it to $XXK/month in revenue as the sole engineer owning software, hardware, firmware, and network infrastructure end-to-end.

• Designed and manufactured custom PCB hardware with ESP32 (Arduino/C++) firmware to power a proprietary arcade credit system, enabling deep hardware-software integration and full control over the payment and session lifecycle.
• Built bespoke backend services to manage credits, user actions, and device state synchronization across machines, maintaining zero production downtime since launch.
• Designed and deployed an on-premises server architecture enabling fully offline operation, eliminating dependency on internet connectivity and ensuring sub-100ms payment latency at all times.
• Engineered, manufactured, and deployed self-service customer kiosks integrating NFC chips, multi-card dispensers, and Square payment APIs — cutting required clerk headcount by 50% and redirecting staff to higher-value customer interactions.
• Built a digital queue management system and customer-facing app that optimized peak-hour throughput, driving an estimated 10% increase in revenue per hour.

Senior Software Developer at ShareSFR (2024-11 – Present)

Sole engineer responsible for designing and delivering an AI-driven document ingestion platform capable of processing 3,000 unstructured legal and financial documents per day into normalized, queryable database models.

• Optimized the full pipeline to operate within AWS micro-instance constraints, reducing per-document processing cost by 75% while preserving throughput and reliability at scale.
• Architected multi-step LLM pipelines using OpenAI models to automate document classification, entity extraction, and date parsing - transforming raw, unstructured input into serialized, versioned records with no manual intervention.
• Designed and implemented a confidence scoring and thresholding system to surface uncertain AI outputs for human review, improving downstream data quality and reducing silent errors in production.
• Eliminated manual document tagging bottlenecks, enabling the business to onboard new data sources faster and materially increasing the volume of documents processed per analyst per day.
• Owned all architecture decisions, data modeling, and operational tradeoffs for a production AI system end-to-end under significant infrastructure and model performance constraints.

Software Developer at Loblaw Digital (2019-11 – 2024-11)

One of 4 engineers trusted with ownership of 2 critical, revenue-impacting services within a 100-person engineering org at Canada's largest retailer.

• Designed and delivered a real-time stock visibility feature for the cart service, integrating live inventory feeds with data-science-predicted stock levels to reduce product substitutions and improve the end-to-end customer shopping experience.
• Overhauled logging and alerting infrastructure across core service components, cutting false positive alerts by 50% while increasing signal fidelity - giving the on-call team clearer, more actionable insight into real system errors.
• Introduced CI/CD performance testing baselines that established continuous visibility into service health, enabling the team to catch regressions before production and maintain P99 SLA compliance across all deployments.
• Reduced P95 API latency by 15% and improved performance for large cart operations by 25% through targeted profiling and refactoring of critical service functions.
• Designed and built new microservice components with a focus on performance, maintainability, and long-term code quality across a high-traffic production system.
