- Observability
Leading like an engineer who still ships.
Promoted to Team Lead in March 2026 after a year of senior engineering at Xytech. Architecture ownership, code review culture, and product translation are non-negotiables.
Mentoring
Pair sessions, code reviews, and growth conversations that raise the team's ceiling.
Team Management
Trust-first leadership — clear ownership, async-friendly cadence, no heroics.
Architecture Ownership
Decisions that age well. ADRs, system reviews, and tradeoffs made in writing.
Sprint Planning
Estimating realistically, slicing work cleanly, and keeping scope honest.
Product Thinking
Pushing back on the right things. Engineering decisions that respect product intent.
Stakeholder Comms
Translating engineering reality into language founders and PMs can act on.
What people who've shipped with me say.
Direct words from teammates, founders, and managers. Placeholder voices below — real testimonials coming soon.
“Abaidullah owns the hardest parts of the system and leaves them better than he found them. Rare combination of speed and rigor.”
Engineering Lead
Director of Engineering · Xytech
