About

Professional summary

I am a product-minded Full-Stack and Mobile Software Engineer with one year of intensive, self-directed production engineering experience. I build responsive cross-platform applications, asynchronous backend services, and AI-powered systems from concept through deployment.

I specialize in Python, FastAPI, Flutter, Dart, and modern API-driven architectures. I enjoy turning ambiguous product requirements into practical, maintainable software with a strong focus on rapid delivery and user experience.

I have hands-on experience designing RAG and semantic-search systems using two-stage vector retrieval, HNSW indexing, cross-encoder reranking, and LLM integrations. My work includes Qdrant Cloud, Supabase pgvector, Google Gemini, OpenAI, and Cohere Rerank.

I build offline-first Flutter applications with responsive interfaces and robust state management using BLoC, Riverpod, and Provider. I also develop backend microservices with asynchronous Python, PostgreSQL, Supabase, Firebase, and RESTful APIs.

I have shipped and maintain public production projects including a fitness RAG copilot, an AI career-matching platform, and a client-side compliance and SAST scanning tool. I am comfortable working independently, taking ownership, and contributing in fast-paced startup environments.

I am immediately available for remote opportunities worldwide and am eager to contribute as a junior software engineer while continuing to deepen my full-stack, mobile, AI, and cloud engineering skills.

Career history

Independent Software Engineer - Full-Stack and Mobile Self-Directed Production Systems

I architect, ship, and maintain three production applications with public codebases, automated tests, and live deployments. My work spans cross-platform Flutter interfaces, asynchronous FastAPI microservices, vector search, AI integrations, databases, and cloud deployment.

For PulseFit AI, I built a cross-platform fitness application and two-stage RAG copilot using Flutter Web, FastAPI, Qdrant Cloud HNSW, Gemini, Cohere Rerank, and Supabase. I implemented 768-dimensional vector retrieval with sub-15 ms retrieval performance, cross-encoder reranking that improved precision to over 94%, deterministic mathematical guardrails, and offline-first client-side state caching.

For JOB SeArCh, I engineered an autonomous AI career agent with semantic candidate-to-job matching. I developed shared latent-space matching with Supabase pgvector HNSW, Gemini Flash scoring, adaptive bias steering vectors, recruiter outreach generation, BLoC-based Flutter Web UI, headless ATS scrapers, and a client-side credential vault.

For ComplianceShield, I created a fully client-side audit-readiness and SAST scanner for SOC 2, ISO 27001, HIPAA, and GDPR controls. I implemented static-analysis rules for exposed secrets, unescaped queries, and insecure dependency patterns with immediate browser-based feedback.
