Alex Nesovic

Need mission-critical systems that scale? I architect bulletproof infrastructure, lead technical teams, and deliver enterprise solutions with Go, Rust, and cloud-native tech.

DevSecOps & Infrastructure

Enterprise Cloud Architecture

I build and maintain the infrastructure that keeps applications running reliably at scale, with monitoring that catches problems before users notice them.

Core Technologies

Kubernetes | self-hosted, GCP or AWS

Deploy and scale apps automatically

IaC | Terraform & ArgoCD

Version-controlled infrastructure changes

OTEL & Grafana

Track performance and catch issues early

Currently helping a crypto protocol company migrate from AWS to GCP while implementing proper monitoring and automated deployments that reduced downtime and maintenence measurably.

High-Performance Systems

Modern Systems Programming

I build performance-critical systems using modern languages: Go for concurrent services, Rust for web3 security, and Zig as a better C/C++ replacement.

Core Technologies

Go | High-throughput services

Concurrent microservices handling millions of requests

Rust & TS | Safety for Web3

Secure smart contracts and blockchain infrastructure

Zig | Drop-in C/C++ replacement

Cross-compilation and zero-dependency builds

Developing smart contract execution engines in Rust and replacing legacy C++ systems with Zig to improve build times and cross-platform compatibility.

Protocol Engineering

Blockchain & Web3 Infrastructure

I architect oracle networks, interoperability protocols, and chain abstraction systems that connect blockchains to real-world data and each other.

Core Technologies

Oracle Infrastructure | SEDA-style

Programmable data feeds with blazing settlement times

Interoperability Modules | Cross-chain

Verification systems for bridges and chain abstraction

Consensus & Validation | PoS networks

Secure validator networks handling significant daily volumes

Building interoperability verification modules and oracle programs that connect 15+ chains with sub-second data settlement.

Bazel Expert

Advanced Build Systems

I optimize build systems and manage complex monorepos that compile faster and more reliably than standard tooling.

Core Technologies

Bazel Migration | v5 → v9

Modernize builds while maintaining compatibility

Custom Rules & Macros

Build tools tailored to specific workflows

Remote Caching & Execution

Distributed builds that scale across teams

Optimizing large-scale monorepo builds for a 50+ engineer team, achieving 90% build time reduction through advanced caching and distributed execution strategies.

Observability & Monitoring

Full-Stack Monitoring

I implement monitoring systems that give you complete visibility into your applications, from user interactions to database queries.

Core Technologies

OpenTelemetry | Traces & Metrics

End-to-end request tracking and performance

Prometheus & Grafana

Real-time metrics and customizable dashboards

Tempo & Mimir | Storage

Scalable storage for traces and long-term metrics

Building comprehensive observability platforms with incident.io-style incident response workflows, reducing MTTR from 2-5 hours to less than 15 minutes by connecting traces to business metrics and automating escalation procedures.

Technical Leadership

Team & Project Management

I lead technical teams while staying hands-on with code, ensuring projects deliver on time without sacrificing quality or team morale.

Core Technologies

Technical Strategy | Architecture

Design systems that scale with business needs

Team Mentoring | 1:1s

Help engineers grow their technical and career skills

Project Delivery | SDLC

Ship features predictably with quality engineering

Leading large-scale engineering teams through critical platform transformations while maintaining enterprise-grade reliability and developing junior talent into technical leaders.
