Senior Backend Engineer with 6+ years of web development experience, including 4+ years
architecting backend systems for high-load, distributed platforms. Built systems that process
~1,000 transactions/second (peak ~3,000/second under load), cut latency by ~57%
through a redesigned message-queuing pipeline, and brought validation time under 400ms —
down from 1,000ms — under heavy concurrent load (200–500 concurrent requests). Deep hands-on
expertise in C#, ASP.NET Core, ABP Framework, PostgreSQL, Kafka, Redis, and gRPC, applying
OOP, Domain-Driven Design, and Clean Architecture to build maintainable, domain-centric microservices.
Comfortable owning a system end-to-end — from database design to API gateway — and recently
extended that ownership into people leadership as an Engineering Manager leading a 9-person team.
Engineering Manager

MISA Group — HRM Solutions
- Promoted to Engineering Manager after 8 months as Senior Developer, staying hands-on in architecture decisions and code reviews across the HRM platform.
- Directed technical decisions for a 9-person cross-functional team (8 engineers mentored directly, plus 1 QC).
- Improved on-time sprint delivery rate from 65% to 90% within the first five months as Engineering Manager, through structured sprint planning, stand-ups, reviews, and retrospectives — a disciplined Scrum cycle.
- Designed and directed the rollout of an in-house AIDD (AI-Driven Development) plugin suite: BaKit for business-analysis automation (cut documentation drafting time from ~5 to ~2 days, ~60% faster, across 70 documents drafted in June–July 2026); DevKit for AI-assisted coding (lifted developer output by ~63%, from 8 to 13 story points/sprint per developer, across 8 developers over 4 sprints); and QcKit for automated test generation (automated ~87% of test cases — 260/300 — within two months of rollout).
- Set and enforced reliability and performance standards across the platform's high-load production systems.
