Chief Technology Officer
Mohammad Harris Tariq
I lead engineering at Paisol Technology. My job is straightforward: make sure every project shipped under our name is something the senior engineer on it would be proud to put their name on. 500+ projects in, that's still the bar — and it's the only one that matters.

The short bio
I'm an engineering leader with 12+ years of production experience — from early-career roles writing high-throughput services, to leading distributed-systems teams, to building the engineering function at Paisol Technology alongside our founder Najeebullah.
At Paisol, my remit is what most agency CTOs avoid: standards. The code-review rubrics, the CI/CD baselines, the observability defaults, the on-call playbooks, the senior-only hiring bar. The boring infrastructure that makes the difference between an agency that ships 10 great projects and an agency that ships 500 — all at the same quality bar.
On any given engagement I'm typically the lead architect on the cloud + infrastructure layer, the second reviewer on critical PRs, and the person who signs off on production launches. If you book a strategy call where the cloud architecture matters — HIPAA, SOC 2, multi-region, embedded analytics — you'll likely be talking to me.
What I work on
Roughly 50% of my time goes to engineering leadership across active engagements — code reviews, architecture decisions, production launches. The remaining 50% splits between cloud + distributed-systems architecture work directly on our larger client builds, and the slow, important work of keeping the team itself excellent: hiring, mentoring, evaluating new tools, and writing the internal playbooks every Paisol engineer follows.
Areas of expertise
Engineering leadership
Sets engineering standards across every Paisol engagement — code review rubrics, CI/CD baselines, observability defaults, on-call rotation, and the senior-only hiring bar that keeps the delivery quality consistent across 500+ shipped projects.
Cloud architecture
Production deployments on AWS, Azure, and GCP — including HIPAA-eligible and SOC 2-ready architectures, multi-region setups, and the cost-optimization playbooks that keep client infra bills predictable as they scale.
AI / LLM systems engineering
Architectural authority on the AI agent stack we ship most weeks — LangGraph orchestration, RAG pipelines, evaluation harnesses, guardrail design, and the observability layer that makes production agents debuggable in month 12.
Distributed systems & scale
Multi-tenant SaaS architectures, real-time pipelines, embedded analytics platforms. Designs systems that handle the boring 95% — auth, billing, search, payments, audit logs — so product teams can focus on what makes their product different.
