Experience

Hands-on technical lead: ~70% IC work (backend systems, AI infrastructure), ~30% engineering leadership. Direct report to CTO.

• Architecture & Cost Optimization: Engineered a decoupled Marketing Engine for growth features, improving system agility while reducing infrastructure costs by 150M+ IDR/year.
• Reliability & Quality: Directed QA roadmap and SDLC across distributed B2B and B2C services — maintained B2B error rates below 10% and B2C below 1% in production.
• AI & Backend Infrastructure: Built the company's AI stack from zero to production — Hybrid Search, RAG pipelines, LangGraph-based agentic workflows, and MCP integrations.
• Team Scaling: Grew engineering team from scratch — 20+ full-time engineers, 10+ interns, 100% post-probation retention through rebuilt onboarding and mentoring.

• Automation & Reliability: Built API testing suites and QA automation that saved 500+ engineer-hours per month, increasing deployment velocity across distributed backend services.
• Backend Development: Led end-to-end development of Subscription modules, Workflow Approvals, and Jack Notification systems for the B2B suite — complex financial workflows built for production scale.

• Verification Systems: Engineered automated verification logic (Auto Payment & EDD) to accelerate transaction processing while maintaining strict financial compliance.
• Growth Features: Built and launched the company's first B2C acquisition and retention systems — Affiliate, Referral, and Loyalty programs — where no acquisition channel had existed previously.

• Backend Development: Delivered roughly half the backend codebase for a supply-chain compliance platform for automotive parts manufacturers (Node.js, Express, Prisma, SQL Server), including role-based access control and company-scoped data filtering across approval workflows.
• Document & Workflow Automation: Built PDF/Excel export pipelines for compliance documents (Certificate of Origin, packaging specifications), automated email notification/approval-routing logic, and legacy-data migration tooling for suppliers moving off manual paper records.

• End-to-End Delivery: Orchestrated the digital transformation of a 500M+ IDR project, successfully launching a synchronized ecosystem (Website, Mobile App, OMS, and WMS) with a 100% on-time delivery record.
• Technical Leadership & Execution: Directed a cross-functional team of 6 developers while contributing 50% of the backend codebase, ensuring high architectural standards throughout.
