Freelance Object-Oriented Programming Developer - Eugene Kordin
Freelance Object-Oriented Programming Developer5.0 (29 reviews)

With over 16 years of industry experience, I am a seasoned Application Architect specializing in mobile development. My journey with macOS and iOS development began in 2011, utilizing Objective-C and Swift, after working extensively with C/C++ and C# on Windows platforms from 2007. I also have hands-on experience with Python and JavaScript, enabling a versatile approach to application design. I excel in crafting project architectures and feature designs, backed by strong expertise in memory management and multithreading. My commitment to delivering high-quality mobile projects is demonstrated through comprehensive code assessments, refactoring, and extensive experience in writing both Unit and UI tests. As a team leader since 2013, I have successfully nurtured a talented group of developers, expanding our team from 8 to 17 members over five years. I focus on developing personalized growth plans, setting and achieving goals, and conducting evaluations, resulting in several team members advancing to senior developer and tech lead roles. I am adept at leading critical projects from conception to deployment for high-profile clients, with a strong focus on the entire project lifecycle.

Freelance Object-Oriented Programming Developer - Suraj Kumar
Freelance Object-Oriented Programming Developer5.0 (20 reviews)

I build software solutions for aerospace and robotics industry ranging from building high fidelity dynamics engine software for mars and lunar landing, docking of satellites to deployment of robotic manipulators in space to building software tools for cyber physical systems ranging from rovers, leg-based robots to aerial vehicles e.g. coaxial helicopters and drones with experience in both low level and high level design. I am also a mentor and I love programming and I love teaching especially programming with C/C++ and Python, Design patterns, Data structures and Algorithms. I love taking on new problems and help solving the problems through systematic approach which is scalable in nature. Through mentoring, I get the opportunity to accelerate my own learning curve by constantly challenging my self with problems from different domains and keep myself up to date with current trends in software design. I believe the best way I can contribute to a better society by sharing my knowledge to others and hope they can build upon that. I always find programming to be much more than learning syntax of a language, its more of an art. Give me an opportunity and I will teach you the art of producing high quality functional codes

Freelance Object-Oriented Programming Developer - Omotayo Iyiola
Freelance Object-Oriented Programming Developer5.0 (1 reviews)

I am a Software Engineer with over 10 years of experience in full-stack development and technical leadership. I specialize in modern web technologies, including JavaScript, TypeScript, React, Node.js, and AWS. My expertise spans frontend frameworks (React, Next.js, Electron), backend architectures (Node.js, Flask), and databases (MySQL, PostgreSQL, MongoDB). I have hands-on experience using Python across AI, backend, and automation projects. One of my major works involved using FastAPI to build a LangChain- and Gemini-powered virtual customer service bot integrated with a MySQL database for an e-commerce platform. This bot handled real-time customer queries, fetched answers contextually, and served as an intelligent interface between users and product data. Additionally, I’ve used Flask to develop an AI voice support system powered by ElevenLabs, integrating Retrieval-Augmented Generation (RAG) for voice-based Q&A experiences. On the infrastructure side, I’ve worked extensively with AWS to deploy, scale, and manage production environments. I’ve used AWS Amplify for CI/CD automation of frontends, EC2 with NGINX for hosting and load balancing, and RDS (MySQL/Postgres) for secure, scalable database management. I’ve also configured Route 53, CloudFront, and S3 Buckets for content delivery and static hosting, ensuring efficient global performance and high availability across deployments. Together, these experiences demonstrate my ability to bridge AI-powered Python backends with cloud-native AWS deployments, ensuring reliability, scalability, and seamless user experiences across both web and mobile environments. I have led diverse projects, from HRIS systems to eVoting platforms, focusing on scalability, security, and system performance. Recently, I developed an AI-driven response evaluator app, enhancing NLP with the Natural library and refining machine learning models, strengthening my AI and model evaluation skills. I developed a social media automation dashboard enabling users to authenticate via Facebook Login, schedule posts, and track engagement analytics in real time. Integrated the Facebook Graph API for user authentication, post publishing, and insights retrieval, while managing webhook updates for page activity. With a collaborative leadership style grounded in values of Excellence, Passion, Integrity, and Commitment, I have led initiatives that increased revenue and improved institutional rankings, including overseeing the creation of over 15 educational applications at Yaba College of Technology. Cross-platform offline-first POS built with Electron (macOS/Windows) featuring secure role-based sessions, robust API sync (idempotent/outbox), high-performance UI (workers/virtualized lists), and production packaging (code-signed, auto-updates). Also, actively use Cursor, GitHub Copilot, and ChatGPT in my day‑to‑day work. * Cursor: I lean on repo-wide context to refactor legacy modules, generate test suites, run multi-file code mods, and rapidly scaffold React/Next.js features. I also use its inline “chat-on-selection” to explain unfamiliar code paths and to produce migration scripts (e.g., Prisma/PostgreSQL schema changes). * GitHub Copilot: Great for fast boilerplate (handlers, DTOs, Prisma models), unit tests, and typed hooks in TypeScript-heavy codebases. * ChatGPT: Architecture brainstorming, prompt engineering for LLM features (LangChain), complex regex, and translating requirements into clean DDD/Clean Architecture boundaries. * Facebook Graph API–powered automation app that enables users to log in, schedule posts, and track real-time engagement analytics using React, Node.js, and Supabase. This combo has materially reduced cycle time on projects like IntelliTest (AI-powered CBT) and my LangChain eCommerce chatbot, where I used AI tools to scaffold multi-turn LLM workflows, write evaluation chains, and iteratively harden the codebase. My goal is to leverage my technical and leadership skills to drive innovation and deliver transformative solutions aligned with business objectives.
