I’m a full-stack developer focused on reliability, performance, and clean developer experience. At Thena (B2B AI), I own core Slack ↔ Platform pipelines used for ticketing, triage, and notifications across multiple customers/tenants. My work centers on graceful fallbacks, data integrity, and observability—so incidents are rare, and recovery is fast. I like shipping measurable improvements: fewer duplicates, faster queries, clearer logs, safer rollouts. Strong bias for simplicity and business impact. - Owned and drove reliability for Slack ↔ Platform flows across tenants: implemented fallback-paths and idempotent operations to deliver ~99.9% uptime on comment and notification pipelines. - Engineered Redis-based throttling and deduplication for channel notifications, reducing duplicate alert rate by ~90% and significantly lowering Slack API consumption. - Optimized database performance, achieving 30-50% faster org/account lookups and improved scalability. - Re-architected Slack message rendering using parallel processing, resulting in 2–3× faster conversion and reduced latency in user-facing workflows. - Instituted structured logging and enhanced error handling to slash mean-time-to-debug and boost production observability. - Champion of data integrity: enforced unique constraints, soft-deletes for comment/ticket entities, and centralized permalink utility to robustly handle deleted/archived messages—ensuring clean audit trails and no duplicate data.

• Architected and owned Thena's Slack-native event ingestion backbone, scaling throughput from 5K to 100K+ daily events — a 20x increase — while sustaining zero message drops at 500K peak load; the reliability infrastructure directly supports enterprise customers including Vercel, Amplitude, and ClickHouse across hundreds of Slack workspaces. • Led the reliability overhaul of Thena's event-driven pipeline — implementing Redis NX-key deduplication, DLQ-backed async recovery, idempotent SQS message handling, and RID-based distributed tracing across the Slack ingestion service — with the architectural patterns adopted as the engineering standard for all new backend services at 100K+ daily events. • Drove end-to-end test coverage for the Slack → SQS ingestion critical path, adding 9,000+ lines of test coverage and pre-commit validation hooks — establishing regression safety for the team's most failure-sensitive data flow and shifting incident response from reactive firefighting to proactive prevention. • Designed rate-limit-aware handling and burst-traffic resilience for Slack API integration, sustaining 99.9% pipeline availability and absorbing 500K peak spikes — 5x daily volume — without latency degradation or message drops across multi-tenant enterprise workloads. • Stabilized and extended integrations across Slack, Microsoft Teams, Salesforce Cases, and Zendesk — including Zendesk alias routing and form field sync — while owning SLA breach notification infrastructure and maintaining enterprise workflow continuity for customers including Vercel, Amplitude, FOX, and Mixpanel. • Championed structured incident response for production-critical failures — SSL disruptions, cache inconsistencies, and integration outages — reducing mean time to recovery from multi-hour events to under 30 minutes and establishing runbook-driven protocols that improved the team's operational resilience.

• Identified and eliminated critical API performance bottlenecks in core request handling paths, reducing p99 response times from 30 seconds to under 2 seconds at peak load — a 93% improvement — directly enabling 195% growth in active users without stability regressions. • Engineered backend logic for student assessment interpretation and automated support triage across 50+ assessment types, translating wellbeing signals into structured decision flows and reducing dependency on manual clinical intervention for institutional deployments. • Architected AI-powered conversation flows using OpenRouter, vector search, and RAG pipelines for a student mental wellness platform — the system's real-time crisis detection capability identified suicidal ideation in at-risk students, directly enabling timely clinical intervention that contributed to life-safety outcomes for 7 students. • Drove platform stability through targeted backend fixes and infrastructure improvements, contributing to a 70% reduction in unplanned downtime and strengthening product credibility for institutional clients including Allen, GEMS, and JMR. • Translated clinical domain frameworks and behavioral assessment data into production backend decision logic spanning wellness triage, risk stratification, and crisis-intervention workflows — cutting time-to-clinical-escalation across 3 institutional deployments and reducing manual interpretation overhead through automated risk-stratification pipelines.
