About

A pragmatic engineering leader who ships outcomes, not just code.

I'm Saim Malik, a Senior Software and AI Engineer. I partner with startups as a hands-on lead, aligning architecture, velocity, and quality so teams can earn investor confidence and scale after the round. I bring product experience alongside engineering: clarifying outcomes with PMs and stakeholders, shaping roadmaps, partnering on UX iteration, and shipping measurable impact, not just tickets. I ship end-to-end across Django, FastAPI, Laravel, Rails, and React/Next.js, and I put machine learning, LLMs, and deep learning to work where it moves the needle: search, automation, auditing, and intelligent workflows. Performance, reliability, and production discipline are non-negotiable.

01

Outcomes over output

I align engineering work to measurable business outcomes — uncovering $40M+ in revenue, reducing defects by 75%, and shaving release cycles by 30%.

02

Pragmatic architecture

Multi-tenant SaaS, event-driven services, and async pipelines — but only when they earn their place. Architecture should serve the team, not the trend cycle.

03

Operational excellence

I treat reliability, observability, and security as first-class features. Robust CI/CD, structured testing, and clean monitoring are non-negotiables.

04

Lift the team

I invest in mentorship, RFCs, and code review standards. Leading 10+ engineers has taught me that great teams compound — clarity and trust are the multipliers.

Experience

Six years of leading and shipping at scale

A timeline of roles where I've owned architecture, mentored engineers, and delivered measurable business outcomes.

AI Powered Career Engine

LLM-powered job discovery, scoring, and application tailoring.

A multi-tenant platform that runs the full job-application loop — discover → score → select → tailor → PDF — on a provider-agnostic LLM layer with JSON-schema-constrained outputs. It tailors CVs, runs CV-to-requirement gap analysis, and generates interview-prep stories, with LangGraph orchestration and pgvector embeddings matching candidates to roles by semantic similarity.

  • Pipeline: discover → score → select → tailor → PDF
  • Multi-provider LLM abstraction with retry/fallback
  • LangGraph + pgvector semantic matching

HealthHub — AI Fitness & Wellness Coach

An AI wellness coach with safety guardrails and a doctor layer.

A Django fitness, nutrition and health-tracking platform with an AI wellness coach and consultation booking. Its guardrail-first pipeline screens every message before it can reach an LLM — refusing medical advice and redirecting to a real doctor — while a single shared service layer powers both the server-rendered Django app and a versioned REST API consumed by an included Next.js frontend.

  • Guardrail-first AI pipeline with audited blocks
  • Shared service layer for Django + REST API
  • Doctor consultations with race-safe booking
