We build and secure scalable cloud infrastructure, harden Linux servers against real-world threats, and deliver full-stack web applications that run reliably in production.
Technologies We Work With
From server hardening to full-stack development, we deliver production-grade infrastructure and applications that businesses depend on every day.
AWS architecture, CI/CD pipelines, Terraform infrastructure-as-code, and production deployment automation that scales reliably.
Ubuntu/CentOS setup, Nginx reverse proxy, SSL automation, and rock-solid server configurations that stay online for months.
Origin shielding, WAF tuning, firewall whitelisting, and Fail2Ban hardening to keep bots and attackers out.
Next.js + Node.js applications, PostgreSQL databases, Stripe payments, and clean API design — built to last.
Custom WordPress development, plugin conflicts, PHP debugging, and seamless third-party integrations (Stripe, Calendly, Zoom).
Grafana, Prometheus, and Alertmanager stacks — so you know about problems before your customers do.
SynTechOps LLC is a Wyoming-registered technology company specializing in production-grade DevOps, server security, and full-stack web engineering. We work directly with founders, agencies, and engineering teams to build infrastructure that stays online and applications that scale.
Led by Muhammad Jahanzeb — a Top Rated Upwork engineer with verified client ratings and a track record of fixed-fee delivery without missed deadlines.
Written specs before any code is shipped
WAF, Fail2Ban, SSH lockdown by default
No surprise bills, no scope creep
Every deploy verified by automated tests
Infrastructure That Just Works
An engineering-first workflow that delivers fixed-fee projects on time, with documentation, tests, and zero surprises in production.
We start with a written specification — endpoints, data models, edge cases, and acceptance criteria — so there's no ambiguity before code is written.
Implementation against the spec with unit, integration, and end-to-end tests. Every PR ships with reproducible build steps and rollback plans.
Full UAT pass on staging, security hardening (WAF, Fail2Ban, SSH lockdown), and load-tested before anything touches production.
Zero-downtime deployment with Grafana/Prometheus dashboards, alerting, and full runbook handover — so your team knows what to do at 3 AM.
Every tool below is something we've deployed, hardened, and monitored on real client infrastructure — not a list of buzzwords.
Production deployments, live infrastructure, and shipped applications — here are the projects we've delivered.
Full production infrastructure for a multi-tenant AI agent platform across two bare-metal servers. Delivered Docker-based container provisioning, Nginx wildcard subdomain routing, Cloudflare DNS-01 wildcard SSL, full security hardening, and a complete Grafana/Prometheus monitoring stack.
End-to-end data pipeline for Baxter International — automatically ingests shipment Excel/CSV files from Microsoft 365 email (Graph API), parses and deduplicates records into PostgreSQL, and serves 5 live Grafana dashboards. Fully automated AWS EC2 deployment via GitHub Actions + Terraform with AWS Secrets Manager integration.
Complete rebuild of a wholesale flower market's annual member-renewal flow, replacing an 82,000-line legacy ScriptCase implementation with a clean modern PHP backend. Authored the full Phase 1 specification (38-table spec doc covering 8 wizard steps, state machine, pricing logic, validation rules, error handling, and security model) and then shipped Phase 2: token validation, draft auto-save, buyer CRUD with soft-delete history, document upload pipeline (UUID-named storage, MIME-validated from file content), Stripe Checkout integration with HMAC-verified webhooks, idempotent payment handling, CSRF protection, race-protected cap enforcement, and a per-session state machine. Hardened the staging deployment with proper nginx access-control rules and PHP-FPM permissions. All 265 tests passing across unit, integration, HTTP end-to-end, and security suites — zero failures — and the existing 9,758-customer production database verified untouched.
Designed, built, and shipped a complete production marketplace for Pakistan's wedding wear resale market. Server-rendered Next.js 16 application with MongoDB, listing management, real-time chat with per-listing unread indicators, secure JWT auth with mandatory email verification, password reset flows, image optimization (Sharp + WebP), rate-limited APIs, and a polished admin panel. Deployed to a Hetzner ARM (CAX11) instance with Caddy reverse-proxy auto-fetching Let's Encrypt SSL on a custom domain. Configured Resend with full DKIM/SPF/DMARC domain verification for transactional emails (welcome, verification, password reset, chat notifications). Generated a Trusted Web Activity (TWA) Android package via Bubblewrap — production-signed APK + AAB ready for Google Play submission. Hardened with idempotency-aware payments hook for JazzCash, anti-enumeration on password reset, ObjectId casting across chat endpoints, and 29/29 automated smoke tests passing on every deploy.
UFW whitelist to Cloudflare IPs, WAF managed ruleset tuning, custom rate limiting on heavy endpoints, and Nginx real-IP restoration.
High-performance EC2 instances optimized for browser-heavy workloads, Parsec remote desktop, Elastic IPs, and CloudWatch monitoring.
WordPress site with Calendly bookings, Zoom auto-generation, Stripe payment processing, and GoDaddy hosting configuration.
Grafana, Prometheus, cAdvisor, Node Exporter, and Alertmanager — 149-panel dashboard with alerting on container, CPU, RAM, and disk thresholds.
Resolved post-upgrade plugin conflicts and theme incompatibilities, restoring blog layout and sidebar functionality on a high-traffic site.
"Working with you has been amazing. The infrastructure was set up exactly to spec, documentation was thorough, and every UAT test passed on the first run. Highly recommended."
"Clear communication, fast turnaround, and zero downtime during the migration. The monitoring dashboard he set up gives us full visibility — exactly what we needed."
"Diagnosed our PHP issue in under an hour and fixed it cleanly. Knew exactly where to look and explained the root cause clearly. Will work with again."
