About Mir Alamin
Top Rated Web Developer & Linux SysAdmin with 12+ years of experience. Completed 680+ projects for hundreds of satisfied clients globally.
Mir Alamin
Hi, I'm Mir Alamin. I build high-performance websites and optimize servers. I operate strictly as an individual freelancer, not an agency—which guarantees that all of your services, setups, and administrative tasks are completed personally by me with premium human craftsmanship. I hold 40+ verified skill badges from industry leaders like Google Cloud, IBM, and the Linux Foundation. Beyond these certifications, I am a continuous learner deeply passionate about advanced Linux, WordPress, web servers, and hosting. While I don't claim to be perfect, my dedication to learning means I'm constantly expanding my expertise and discovering new solutions to complex problems every day.
My journey with technology began early—I started using a computer when I was just 9 years old. I first connected to the internet when broadband was barely available in Dhaka city, experiencing the web at a blazing 64Kbps! My first online messaging platform was Yahoo Messenger, and I've been deeply fascinated by the internet and its evolution ever since.
Although based in Dhaka, I provide dedicated remote server administration to businesses primarily in the USA, Canada, UK, and Australia. I am highly flexible with time zones (seamlessly covering EST, PST, and GMT) and adapt to wherever my clients need me. Previously, I spent 6-7 years living in Qatar, where my family still resides.
If you need a reliable Linux server expert, I ensure your websites and servers are fast, secure, and always online. From setting up high-performance systems to troubleshooting and fixing complex issues, I keep your web infrastructure running smoothly so you can focus on growth!

In addition to agency partnerships, I provide dedicated website and server management for numerous prominent law firms across the USA, including Rogers | Beltran LLP, Ott Law Firm, Spangler Law, Zen Law Firm, Heather C.

Linux Server Architecture & Reliability Standards
Every production server, cloud cluster, and web application managed by Mir Alamin adheres to strict, battle-tested system administration principles designed for sub-50ms latency, zero data loss, and impenetrable security.
1. Linux Kernel & Web Server Optimization
Default Linux and Nginx installations are configured conservatively for generic workstations, causing severe bottlenecks under heavy concurrency. I optimize the entire stack from the kernel layer up:
- ▸TCP BBR Congestion Control: Replaces legacy Cubic algorithm to maximize network throughput and slash packet transmission delay.
- ▸Sysctl Socket Limits: Increases
net.core.somaxconnto 65535,net.ipv4.tcp_max_syn_backlogto 8192, and sets file descriptors (fs.file-max) to 2,097,152. - ▸PHP-FPM Process Pool Tuning: Dynamic process sizing based on available RAM, preventing memory starvation while keeping cold-start latency near 0ms.
- ▸Redis Object Caching over UNIX Sockets: Eliminates TCP loopback overhead to deliver sub-5ms persistent database query caching.
2. Zero-Downtime Infrastructure Migrations
Migrating live production platforms, busy WooCommerce checkout funnels, or high-transaction SaaS databases requires rigorous engineering to guarantee zero lost orders and continuous user access:
- ▸Low-TTL Staged DNS Cutovers: TTLs on authoritative NS/A records are reduced to 60 seconds 24 hours in advance to guarantee instantaneous global propagation.
- ▸Differential Rsync Delta Streaming: Initial 100GB+ file trees are pre-synced while origin stays active; only final byte deltas are moved during switchover.
- ▸ACME Pre-Issuance SSL Verification: TLS certificates are verified and installed before DNS cutover to ensure zero browser warning interstitials.
- ▸Sub-60s Database Cutover: Origin database locked with single-transaction snapshotting, imported to target, and verified with zero dropped carts.
3. Forensic Disinfection & Cyber Defense
When a web server or WordPress application is compromised, surface-level plugin cleaners leave persistent PHP backdoors intact. My forensic remediation eradicates malicious payloads permanently:
- ▸Upstream Checksum Verification: Core CMS and plugin files are validated against official repository SHA-256 hashes to eradicate obfuscated eval() webshells.
- ▸Database Payload Neutralization: Sanitization of rogue administrative accounts, malicious cron schedules, and serialized database spam redirects.
- ▸PHP Execution Isolation: Disables dangerous functions (
exec, shell_exec, system, passthru) and enforces strictopen_basedirboundaries. - ▸Expedited Search Delisting: Rapid submission of clean forensic audits to Google Safe Browsing, Norton, and McAfee to restore organic search traffic.
4. SLAs, Direct Accountability & Upwork Record
Unlike agencies that route your mission-critical server infrastructure through junior account managers, WebCare Pro is operated exclusively by Mir Alamin with direct, senior-level ownership:
- ▸Sub-15 Min Emergency Triage: Immediate engineer response for server outages, memory panics, database deadlocks, or SSL expiration alerts.
