Real outcomes from real engagements — not just shipped features, but measurable business results.
Transformed a basic proof-of-concept into a secure, scalable, real-time AI conversation-analysis product. Delivered to the first customer in six months; scaled from 100 to 15,000 calls per day across multiple customers, integrations and regions. High test coverage: unit, E2E, and scale tests throughout.
Worked in diverse roles as standalone developer, Team Leader and Architect, led work across diverse technologies: async microservices, RabbitMQ pipelines, AWS Lambda + SQS infrastructure, C++ Build Systems. Established all important good practices, uniform work environments reducing friction, code quality standards, and CI/CD infrastructure and design, including tests at all levels: E2E, Unit and Scale Tests. Led routine development work as well as major architectural initiatives, including research, technology selection, and overseeing implementation by other engineers.
Engineered the core of a WiFi security product from scratch: from low-level networking and WiFi monitoring to analysis tools, Embedded Linux system configuration, and comprehensive testing infrastructure. Handed off a production-ready prototype system supporting a wide range of cyber security applications, with robust tooling, orderly and efficient deployment capabilities to edge devices, with security built in from the start.
Took ownership of a large, convoluted CMake-based build system and restored order:
removed duplicated and overly complex logic, eliminated dependency on legacy Python versions,
and introduced build-specific tailored virtual environments, untagling misconfiguration
of Finder Modules, e.g. FindPython3, resolving missing Python.h headers etc.
Resolved deep-rooted sensitivity to dependence on legacy, stateful and opaque development servers.
Decomposed a convoluted both native and cross compiling scenario into a much cleaner, more modular and understandable structure.
Maintained constant communication with the customer's team and tech leads throughout to verify impact at every step.
Shaped both the product and the engineering culture at a defensive cyber security startup. Designed the AWS Lambda + SQS backend infrastructure, defined company-wide testing guidelines (E2E, integration, unit), and established a Standard Development Environment that eliminated whole classes of environment-dependent bugs, while at the same time allowing developers to keep their favorite tools. Negotiated with Product to translate product requirements into verifiable, fact-based tests. Led research and prototyping of new technologies, oversaw major technical transitions, and mentored the team on code quality standards and practices. Research, prototyping and embedding of technologies including: S3, AWS Aurora, SQS, Lambda, Celery, docker, Gitlab-CI, networks
Deep, hands-on expertise across the full software lifecycle — from whiteboard to production.
A broad, deep toolkit built over 15+ years of hands-on engineering.
Quality of Development leads to Quality of Life - for Customers, Executives, Product Managers, and Engineers.
For startups, Quality means resilience to change: move fast without breaking things, and be in control.
Ride fast without the wheels coming off.
