Tech Lead with 6+ years in software development, including 4+ years owning backend
architecture for high-load, distributed systems. Recently directed technical decisions for a
9-person team, building on a track record of systems that process ~1,000 transactions/second
(peak ~3,000/second under load), cut latency by ~57%, and brought validation time under
400ms (down from 1,000ms) under heavy concurrency (200–500 concurrent requests). Led the design
and rollout of an in-house AI-Driven Development (AIDD) toolkit that lifted developer output by
~63% and automated ~87% of the team's test cases. Strong technical foundation in C#,
ASP.NET Core, ABP Framework, Microservices, and Clean Architecture, paired with hands-on mentoring,
code review standards, and cross-functional delivery.
Tech Lead (Engineering Manager)
Mar 2026 – Sep 2026
MISA Group — HRM Solutions
- Promoted from Senior Developer within 8 months to lead a 9-person cross-functional engineering team, owning technical direction, architecture, and code-quality standards across every HRM workstream.
- Drove technical planning and design reviews, turning product priorities into an actionable engineering roadmap and improving delivery predictability across the team.
- 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 rolled out an in-house AIDD (AI-Driven Development) plugin suite to standardize and automate the team's workflow:
- BaKit — automated business analysis, cutting average documentation drafting time from ~5 to ~2 days (~60% faster) across 70 documents drafted in June–July 2026.
- DevKit — accelerated coding with correct syntax and business logic built in, lifting developer output by ~63% (8 → 13 story points/sprint per developer) across 8 developers over 4 sprints.
- QcKit — automated ~87% (260/300) of test cases within two months of rollout, producing more reliable QC reports.
- Mentored 8 developers through code review and pairing, and set reliability standards across the team's high-load production systems.
