01 Profile

6 years in web development, with 4+ years deep in backend systems — grounded in data structures, algorithms, software architecture, and database design. I build maintainable, domain-centric systems with OOP & Domain-Driven Design, and work comfortably full-stack from PostgreSQL to Angular & Next.js. Recently led a team as Engineering Manager, building AI-driven development tooling to automate how the team ships.

Engineering Manager ↗

Stepped up to Engineering Manager and led a 9-person cross-functional engineering team — owning technical direction, delivery, and code-quality standards, running the Scrum cycle and design reviews, aligning product and engineering priorities, and mentoring developers while driving reliability across high-load production systems.

  • Lifted on-time sprint delivery from 65% to 90% within five months by tightening the Scrum cycle — planning, stand-ups, reviews, and retrospectives.
  • Designed and directed the rollout of an in-house AIDD (AI-Driven Development) plugin suite to automate the product & team workflow.
  • BaKit — automated business analysis, cutting documentation drafting time from ~5 to ~2 days (~60% faster) across 70 documents.
  • DevKit — accelerated coding with correct syntax and business logic, lifting developer output by ~63% (8 → 13 story points/sprint).
  • QcKit — automated ~87% of test cases (260/300) and generated more reliable QC reports.
