Resume

A self-hosted omnichannel platform running customer service and content operations for English Home Libya — catalog-true answers, photo recognition, reliable publishing, and human handoff.

Problem

A retail brand needs one reliable system for Arabic product questions, image-based identification, catalog pricing, social publishing, and human takeover across Facebook and Instagram.

Contribution

Designed, built, deployed, and operate the platform solo — message ingestion, matching engines, bilingual admin console, Content Studio, durable worker, and self-hosted infrastructure.

Result

Live for English Home Libya: catalog-true answers, exactly-once publishing controls, safety guards grounded in real incidents, and immediate human handoff when intent becomes commercial.

A complete retro space shooter in bare-metal C, released as a drag-and-drop UF2 — and fixed after its first run on real hardware exposed a defect no simulator caught.

Problem

The ST7796S panel takes roughly 39 ms to receive a full frame over SPI — by itself more than a 25 fps budget — on a dual-core Cortex-M0+ with no FPU (design calculations, not on-hardware measurements).

Contribution

Designed and wrote the whole game bare-metal, solo: the dual-core pipeline, 24.8 fixed-point math, DMA/SPI streaming, a testable HAL with a desktop host harness, and the release engineering.

Result

Released as drag-and-drop UF2s with green CI; the first run on real hardware exposed a panel-init defect no simulator caught — fixed and documented the same day in v1.0.1.

A hand-wired push-to-talk voice assistant: custom PIO audio capture on the device, streaming speech recognition and permission-gated tools in a self-hosted backend.

Problem

The SPH0645 microphone's pin arrangement made the stock I2S receiver unusable on this build — and a voice terminal needs the whole chain (capture, transport, recognition, tools) to hold together.

Contribution

Hand-wired the device, wrote the PIO/DMA capture firmware and display code, and built the standalone self-hosted control plane any WebSocket client can join as a device.

Result

A released two-repository system verified end-to-end by a fully offline integration test in CI; in use it typically responds within a couple of seconds (observed, not benchmarked).

An Arduino climate/appliance controller with sensor-driven fan control, a four-mode state machine, and an over-temperature safety cutoff — built as a two-person university team.

Problem

Exercise the core embedded-systems toolkit — ADC sampling, PWM actuation, debounced GPIO, a single-wire sensor protocol, UART logging — as one coherent appliance controller on real hardware.

Contribution

A two-person team project with Paola Dorado Galicia: both of us are credited for design, firmware, and testing; I maintain the repository, documentation, and schematics.

Result

A working four-mode controller with a 35 °C safety cutoff, eight documented build states, a schematic in three formats, and a candid limitations list.

A live English/Turkish site for an Istanbul construction-materials supplier: static-first Next.js, a selective 3D scene with a static fallback, and a Playwright smoke suite.

Problem

An Istanbul construction-materials supplier needed a credible bilingual web presence: a real equipment catalog, an RFQ-style contact flow, and English/Turkish parity.

Contribution

Designed, built, and deployed the whole site solo — a typed content layer, documented server/client boundaries, and one deliberate 3D scene with a static fallback.

Result

Live at tr-miramar.com with a Playwright smoke suite green in CI and documented architecture, SEO, accessibility, and content-restraint rules.

Small VHDL designs treated like real releases: exhaustive self-checking testbenches, CI simulation with GHDL, Vivado waveforms, and Basys 3 pin constraints.

Problem

Classroom digital logic usually ends at a waveform screenshot — unreproducible and unverifiable by anyone else.

Contribution

Rebuilt the coursework as real releases: self-checking testbenches sweeping the entire input space, GHDL simulation in CI, Vivado waveform captures, and Basys 3 pin constraints.

Result

512 of 512 adder vectors and all 36 decoder vectors green in CI on every push; on-board bring-up is author-attested and labeled as exactly that.
