base of operations
positioned for international projects, operators and high-speed execution.
Dubai / DevOps / CTO / SaaS / systems engineering
I build technical systems that scale, automate and sell.
I’m David Rodriguez, also known as esedark. I work at the intersection of DevOps, SaaS, infrastructure, automation and product execution. I help companies build serious systems: custom software, growth automation, hardened infra and technical operations that actually move revenue.
technical leadership
product decisions, architecture, infrastructure and execution under pressure.
build + scale
from MVPs to internal systems, automation engines and revenue-driven tooling.
tactical capabilities
Technical services for founders, operators and companies that need real execution.
DevOps & infrastructure
Servers, deployment pipelines, observability, scaling strategy and hardened environments for demanding operations.
Worldwide proxies
Proxy operations and global routing capacity for high-scale technical use cases and distributed workflows.
Automation & bots
Automation systems, scraping, growth workflows, bot operations and tools that turn time into leverage.
Phone farms, Android operations & SaaS
Phone farms, Android device operations, Reddit, Instagram and currently Google Maps workflows, plus SaaS, custom panels and revenue-driven software.

profile
Operator mindset. CTO execution. SaaS builder mentality.
Think in systems
I focus on bottlenecks, throughput, leverage and operational clarity.
Build with intent
No useless complexity. No decorative code. Just tools that create advantage.
Lead technically
I can sit at the CTO layer or go hands-on when execution is what matters most.
Ship for business
The objective is not to “build tech”. The objective is revenue, control, speed and scale.
blog / posts / ideas
Writing, build logs and technical thinking with commercial intent.
