SUMMARY
Senior Frontend Engineer with 8+ years of Angular expertise (v4 → 18), building production applications across
healthcare, music industry, and real estate. Core strengths: cross-component state management with NgRx,
performance optimization (cut module load time from 30s to under 1s), and custom UI engineering — including a
WYSIWYG document designer that automated 80% of manual clinic workflows. Led a module squad at Sony
Music within a 40-person team and drove CI/CD improvements that saved 4–5 hours of team idle time daily.
Comfortable stepping beyond frontend when needed — shipped a full-stack real estate platform with NestJS,
AWS, and Python microservices.

EXPERIENCE
Lakmus Medical — Senior Frontend Engineer
October 2023 – October 2025 · Remote
Angular-based CRM/EMR platform serving clinics across Ukraine.
— Designed and built a WYSIWYG document constructor with embedded Angular components from scratch —
replaced manual HTML templating, automating ~80% of document workflows for clinic staff.
— Introduced NgRx into a legacy codebase originally written by a backend developer — eliminated full-page
reloads and ad-hoc refetching, making the architecture flat and predictable.
— Integrated medical imaging hardware so scans and results land directly in patient records.
— Maintained 3 product surfaces in parallel: main app for doctors, dashboard mode for hospital monitors, and
a lightweight patient portal.
— Extended the dynamic form system to support new field types without redeployment.
Stack: Angular 14+, TypeScript, NgRx, RxJS, Angular Material, SCSS.

Angular platform for music industry operations; team of 35–45 engineers split into per-module squads.
— Group Lead for one module squad (frontend + backend + QA); substituted for the main Tech Lead during
absences.
— Rebuilt a custom scheduler module — cut load time from ~30s to ~0.7–1.2s via OnPush, trackBy, and
RxJS/state cleanup.
— Proposed and drove CI/CD automation with DevOps: PR approved by 2+ devs → ticket auto-moves to QA
→ auto-deploy to test env. Eliminated ~30 min deploy wait per ticket, saving ~4–5 hours of idle time per day
across the team.
— Mentored junior developers; one promoted to mid-level during my tenure.
— Bridge between UI team and Backend/DevOps for cross-team requirement definition.
