Aiccountant

AI-Native Fullstack Engineer

Aiccountant

01/2026 - Present

Led the WhatsApp Customer Service AI Agent rewrite on Cloudflare Agents SDK and Vercel AI SDK with 7+ tools (knowledge-base search, transaction management, human escalation), multimodal Gemini Flash receipt auto-processing from photo uploads, Telegram-based human handoff, and a real-time admin conversation viewer for live message intervention
Designed and shipped the user categorization rules engine that auto-categorizes new transactions by merchant name and short-circuits the LLM pipeline on hit. Pattern matching combines substring, trigram, and Gemini embedding similarity to survive messy bank-descriptor variants, with system-suggested rules after detecting repeated miscategorization and atomic retroactive application across historical transactions
Built the merchant normalization pipeline that turns inconsistent bank-statement counterparties into canonical merchants. Async enrichment runs through Brave Search (Indonesia-geo) and Gemini 3.1 Flash structured output, gated by a Telegram admin review queue before promotion to a canonical merchants table backed by OpenAI embeddings for semantic lookup
Powered 45,000+ AI workflow runs at 96.2% success rate across Gmail ingestion, email classification, and agent execution, instrumented with PostHog product analytics and Sentry user-journey traces across all Cloudflare Workers, routed through Cloudflare AI Gateway for unified LLM observability
Designed the marketing landing page end-to-end (animated phone-simulation hero auto-cycling through product tabs, interactive product demos, testimonial carousel, multilingual ID/EN, PostHog CTA funnel tracking; built on Remix + Framer Motion) and the budgeting feature (Smart Budget AI-suggested monthly limits, Manual Budget income-based allocation, per-category traffic-light indicators), backed by PowerSync offline-first reactive queries computing budget vs. actual in real time

Built Shopee platform connection module with OAuth 2.0 flow, HMAC-signed token exchange, encrypted token storage, Redis caching, and background refresh, providing multi-shop support with status and health endpoints
Established versioned database migrations (Goose) and standardized API response envelopes across services, improving schema evolution safety and client integration consistency
