Technology and scope of work: As software developer working on various STB development projectsworking with Broadcom, ST and ALi chips, making set top boxes for worldwide markets ( Direct TV, Dish USA, SKYUK TV , Claro Colombia) .

• Integration and development of DVR (Digital Video Recorder) and PVR (Personal Video Recorder) functionality, as well as Video on Demand (VOD) services.
• Expertise in subtitle systems: DVB Subtitles, DCII Subtitles, and CEA-608/708 Closed Captions, ensuring fullsupport for STB devices.
• In-depth knowledge of DVB (Digital Video Broadcasting) standards and MPEG-2 systems, with extensive experiencein resolving issues related to parsing and handling EIT, NIT, SDT, and PMT tables.
• Integration and support for advanced security architectures using Nagra solutions, providing robust content protectionfor broadband services.
• Extensive experience in audio and video synchronization and optimization of tuner performance.
• Skilled in building embedded Linux systems using Buildroot and Yocto, with the ability to create and apply custompatches to the Linux kernel.
• Developed OTA (Over-the-Air) and USB-based firmware update mechanisms for STB platforms.
• Designed and maintained the architecture for a UI project using the QT framework, later migrating to LVGL andNode.js on embedded Linux platforms.
• Experience in debugging and writing device drivers for audio and video decoding in STB systems, including bugfixing and working with Device Tree Compiler (DTC).
• Implemented QR Code generation etc .
• Deep understanding of video codecs, including H.264 and H.265, and audio codecs such as MP3, AC3, and EAC3.
• Experience with Android-based STBs, including JNI (Java Native Interface) and NDK (Native Development Kit) development.

Additional Projects:

• Construction Camera Description: Raspberry Pi Zero paired with a SIM7600G-H 4G HAT module was used to enable real-time video/audiostreaming to AWS Kinesis.
• A custom GStreamer pipeline was developed to ensure low-latency streaming over 4G,optimizing data flow and reducing transmission delays.
• The project involved fine-tuning network settings and pipelineconfigurations to handle the constraints of 4G networks, ensuring reliable and efficient streaming to the AWS cloud.2.
• Firmware Project Bitpart Description: In this project, a secure system update mechanism was created for the Wi-Fi HaLow TXW8301 moduleby leveraging existing resources such as efuses, the W77Q SDK, and its built-in encryption scheme.
• The primary goalwas to ensure firmware integrity and confidentiality by implementing firmware encryption or obfuscation.

• Developing and supporting applications for Audio over IP using AES67 and AES70 standards.
• Expertise in handling streaming and control protocols, including RTP/RTCP, RTSP, SIP, and SDP.Proficient in network analysis using WireShark for debugging and monitoring network traffic.
• Strong understanding of Layer 2 and Layer 3 networking protocols, as well as hands-on experience with TCP socket programming and Linux networking.
• Extensive experience with GStreamer pipeline development, including writing custom applications for managingand processing audio streams.
• Configuration and setup of Texas Instruments (TI) Audio Amplifiers using ALSA (Advanced Linux SoundArchitecture).
• Experience with Bluetooth Low Energy (BLE) technology integration.
• Developing and maintaining system update mechanisms for Soundbars, including both OTA (Over-the-Air) andUSB-based update solutions
