Systems-focused engineer who builds performance-critical, production-shaped software across three domains that rarely meet in one portfolio: algorithmic trading engineering, full-stack SaaS, and DevOps / cloud infrastructure. Low-latency event-driven architecture, strict testing and typing discipline, security-by-default and unusually honest documentation: I ship the code and the verdict on whether it actually works.
מהנדס עם ראייה מערכתית הבונה תוכנה ביצועית ברמת production בשלושה תחומים שנדיר למצוא יחד: הנדסת מסחר אלגוריתמי, SaaS פול-סטאק, ותשתיות DevOps/ענן. ארכיטקטורה מונחית-אירועים בזמן-תגובה נמוך, משמעת בדיקות וטיפוסים, אבטחה כברירת מחדל ותיעוד כן: אני מפרסם גם את הקוד וגם את המסקנה אם הוא באמת עובד.

Production-Ready by Default: every codebase is written with exhaustive error handling, strict validation layers, and dependency injection to guarantee full offline testability.
- Low-latency & decoupled async background workers ensure blocking I/O or remote IPC never halts execution; critical paths avoid allocation churn and GC spikes.
- Security-first secrets never enter version control (
.env.exampleonly), credentials encrypted at rest, demo-guards on anything touching real money, hardened SSH/containers. - Verifiable rigor mypy-strict, coverage-gated test suites (FreqTrading ships 445 passing tests; the Docker CLI holds 100% coverage), CI that gates on every push.
- Honest documentation I record strategies that lose under realistic costs instead of
hiding them, and track every system with a file-based lifecycle protocol
(
STATUS.md,DECISIONS.md,PROGRESS.md).
Ultra-low-latency, event-driven MT5 execution engine. Decouples an async M1 candle feed from a pure
synchronous IDLE → RANGE_DEFINED → BREAKOUT → EXIT), with ATR trailing,
daily-loss circuit breakers, a self-contained MQL5 EA port, and 445 passing tests.
Full-stack prop-trading platform: React 19 · Three.js/WebGL · Express 5 · Drizzle/Postgres · Stripe. Live broker WebSocket streaming, master→follower copy engine, risk/rule engines, encrypted-at-rest credentials — typed end-to-end with Drizzle + Zod.
Typed Typer CLI (mypy strict, 100% coverage) + read-only/non-root/cap-dropped compose stack + SHA-pinned CI with Trivy scanning, CycloneDX SBOMs, and GHCR publishing.
Terraform-provisioned EKS (multi-AZ, GPU node group) serving a distroless Go inference microservice instrumented with Prometheus p50/p95/p99 latency histograms.
