Understand the business constraint
Before choosing a solution, clarify who is affected, what is costly, and what must remain true.
About Irfan
A senior engineer who thinks about the whole product.
I work with startups, SaaS founders, CTOs, product leaders, and engineering teams on the systems that connect product decisions to production reality.
The short version
I build SaaS, AI, and integration systems that teams can keep owning.
My work spans backend and frontend implementation, product workflows, APIs, billing, data boundaries, and the decisions around shipping and handoff.
Founder / product context
ThreatIP keeps the decisions grounded.
Having built and now operating a live product means living with onboarding, billing, support burden, infrastructure, and the next release—not only completing a ticket.
How I work
Calm execution, visible progress, clean handoff.
The relationship stays direct. You should know what is moving, what needs a decision, and what the implementation leaves behind.
Make the system legible
Architecture, data flow, permissions, and failure modes should be understandable to the team.
Ship in useful increments
Small, visible steps create earlier feedback and fewer surprises near the end of a build.
Leave the team stronger
Code, documentation, and handoff should give the next engineer context—not another mystery.
Technical range
Broad enough to own the boundary between layers.
Technology is evidence of capability, not the headline. The useful question is what the system needs to do.
Product engineering
SaaS MVPs, multi-tenant architecture, dashboards, admin workflows, roles, onboarding, and modernization.
AI systems
Agents, tool calling, structured outputs, MCP, RAG, human approval flows, and workflow design.
Revenue systems
Stripe subscriptions, metering, webhooks, payment states, portals, tokenization, and billing operations.
Backend & infrastructure
Laravel, PHP, Node.js, Express, NestJS, PostgreSQL, MySQL, MongoDB, Redis, Docker, Nginx, and AWS.
A useful engagement
You need an engineer who can own the outcome.
That may be a defined sprint, a product slice, a difficult integration, or continued engineering alongside an existing team.
