About
Software engineer at the edge of telecom, networks, and product.
I am Milan Maksimovic, a senior software engineer and CEO of OmaxTelecom. I am most engaged when a problem sits between product design, provider integrations, and the networks that have to stay up while customers integrate.
What I do day to day
API architecture, control planes, and the operational layer around messaging, connectivity, and voice.
My day-to-day work mixes API architecture, Laravel backends, Go services, React control planes, and the operational tooling around messaging, connectivity, and voice. I like interfaces that make implicit telecom complexity explicit: states, retries, usage, and permissions partners can reason about without reading your internal runbooks.
How I work
Interoperable adapters, multi-tenant admin UX, observability, and security defaults that survive deadlines.
I prioritize interoperable provider adapters, multi-tenant admin experiences, reliable observability, and security defaults that do not get bypassed when deadlines appear. I evaluate tools such as Redis, PostgreSQL, RabbitMQ, Grafana, WireGuard, Cloudflare, and Hetzner-hosted infrastructure when they match the reliability profile a telecom product needs. Messaging stacks may involve SMPP-focused components; voice work may touch SIP proxies and platforms I architect around, without claiming every upstream project is mine to ship.
I do not list unverified employers, certifications, or years-of-experience metrics here. This site describes the kind of work I do and the systems I am building now.
Expertise
The layers I work across when building products that partners can integrate and operate.
Telecom and connectivity
eSIM and roaming data flows, wholesale SMS and SMPP, SIP and VoIP integrations, and numbering workflows that partners can actually operate.
Software engineering
PHP and Laravel backends, Go services, React dashboards, API design, and full-stack product work where admin UX and developer UX both matter.
Networks and infrastructure
Linux hosting, DNS, Nginx, VPN and firewall segmentation, virtualization, and monitoring stacks I architect around for predictable operations.
Security and reliability
Authentication, 2FA, scoped access, audit-friendly controls, secure routing, and resilience patterns for services that cannot fail quietly.
Product and systems design
Multi-tenant platforms, white-label workflows, provider abstractions, and usage plus billing models that match how telecom products are sold.
