Fasih Ullah SaleemSolutions Architect

Solutions Architect | End-to-End Systems | Backend | IoT | Cloud

I design and deliver end-to-end systems that span backend services (Python/FastAPI, PostgreSQL), IoT and embedded devices, cloud connectivity and web frontends. I work on system architecture, technical feasibility and deployment (Docker, Nginx, Linux, VMware ESXi), and collaborate across electrical, software and industrial teams. Electrical Engineering background (CGPA 3.79/4.00) with a track record of taking solutions from concept through deployment and operational support in international teams.

Open to remote and on-site roles worldwide · Based in Pakistan · Available for freelance, contract and hobby-project work

In the stack

Where a solutions architect sits in a connected product.

Every layer, from the circuit board to the model on top: this role holds the whole system in one head and builds each layer of it.

Relevant projects

Solutions Architect work, built and photographed on my own bench.

Each card opens the full story: what it does, how it was built and which layers of the stack I built myself.

  • Custom four-layer PCB for the fleet tracker on a cutting mat, with GPS patch antenna, GSM module and screw terminals

    Lead: firmware, PCB and integration

    An end-to-end fleet telematics system built on a custom STM32F427 board. The device reads GPS position and MPU6050 motion data in real time, detects accidents and rollovers, and streams everything over a SIM800L GSM link to a web dashboard. A full power subsystem handles automatic switching between the vehicle battery and an onboard backup, with charging and protection circuitry, so the unit stays online even if main power is cut.

    • GPS
    • GSM
    • IAR
  • IoT sensor node on a breadboard, microcontroller board wired to a temperature and humidity sensor

    Embedded + cloud pipeline

    An IoT data pipeline that takes readings from embedded sensor nodes and publishes them over MQTT to a cloud database, where they feed into monitoring applications. The project demonstrates the full telemetry loop: device acquisition, lightweight pub/sub transport, persistence, and live visualization.

    • Cloud DB
    • Embedded
  • Open desktop workstation showing the graphics card used to run local language models

    Research & prototyping

    A local-first AI assistant built on open-source LLMs running entirely on-device. I explored Retrieval-Augmented Generation and vector-database concepts to ground the model in a private knowledge base, then experimented with prompt engineering, conversational interfaces, and agent workflows, evaluating model quality, hardware requirements, and deployment trade-offs along the way.

    • RAG
    • Vector DB
    • LM Studio
  • Four-wheeled robotics vehicle with stacked microcontroller boards, motor driver and an ultrasonic sensor

    Embedded control

    A robotic vehicle controlled over Wi-Fi, pairing an STM32 for real-time motor and sensor control with an ESP32 handling wireless communication. It supports both a manual remote-drive mode and an autonomous navigation mode, showcasing tight coupling between a wireless link and an embedded control loop.

Questions

What people ask before hiring a solutions architect.

What does a solutions architect do on a small product team?

Decides where each feature should live, device, backend or client, what the interfaces between them cost, and which trade-offs the field will forgive. I design that structure and then build the layers myself, so the architecture is never a document nobody implements.

Do you work remotely with international clients?

Yes. I am based in Pakistan and open to remote and on-site roles worldwide. My current role is with a multidisciplinary engineering and software team, so async, documented, cross-time-zone work is the normal mode.

Can you architect a system that includes hardware as well as software?

That is the specific case I am built for. My fleet tracker runs from a custom STM32 PCB over GSM to a web dashboard; my sensor platform runs from embedded nodes over MQTT into a cloud database. I own both ends of the air gap.

What is your stack for backend and deployment?

Python with FastAPI or Django, PostgreSQL or SQL Server, Redis where it earns its place, and Docker + Nginx on Ubuntu Linux, including virtualized environments on VMware ESXi that I administer myself.
