Work experience

Senior associate

from 11.2023 to 04.2026 (2 years 6 months)
Andersen Lab, Remote (IT)

Designed and built a nightly data synchronization service using FastAPI and Python, storing processed results in PostgreSQL and Elasticsearch so that reporting workloads never impacted live production traffic.
Migrated a legacy PHP backend entirely to Python-based NestJS services, restructuring the data layer and resolving long-running query failures under peak load.
Built REST and GraphQL APIs in Python/FastAPI consumed by web and mobile clients, managing versioning, backward compatibility, and staged rollouts across teams.
Implemented Redis caching and RabbitMQ-based background job processing using Celery workers, reducing synchronous request failures during traffic spikes by a significant margin.
Optimized PostgreSQL and MySQL performance with connection pooling, read replicas, and query tuning - reducing p95 latency under sustained load.
Built an AI agent pipeline using LangChain and the OpenAI API to automate internal data classification tasks, saving the operations team roughly 60% of manual review time.
Deployed Python services on AWS (EC2, RDS, S3) and containerized them with Docker and Kubernetes, fixing autoscaling and health-check issues that were causing production downtime.
Established CI/CD pipelines with GitHub Actions and Jenkins, cutting deployment rollback time to under 10 minutes.
Applied Domain-Driven Design and Clean Architecture when decomposing a growing monolith into smaller Python services, improving developer onboarding time significantly.
Mentored 3 junior developers through code reviews, architecture walkthroughs, and pair programming on complex Python backend problems.

Full stack developer

from 09.2019 to 11.2023 (4 years 3 months)
TRIXICON LTD, Remote (IT)

Built and maintained Python-based REST APIs for user authentication, product catalog management, and order processing - forming the backbone of the marketplace backend.
Integrated third-party payment gateway and shipping provider APIs, resolving data format mismatches and authentication failures that had been blocking production deployments.
Optimized slow PostgreSQL queries by analyzing query plans, adding targeted indexes, and rewriting inefficient SQL - significantly reducing response times on high-traffic endpoints.
Developed a user management dashboard with React and Next.js, collaborating directly with designers and introducing SSR to improve page performance and SEO.
Built responsive, accessible UIs with Tailwind CSS and Material UI across the marketplace frontend.
Maintained CI/CD pipelines with GitHub Actions and contributed to deployment process improvements across he engineering team.
Experimented with early LLM integrations for product search and recommendation features, building confidence with AI API tooling.

Junior associate

from 07.2017 to 09.2019 (2 years 3 months)
ACCENTURE PHILIPPINES, Remote (IT)

Built and maintained small web features in JavaScript and React, following team coding standards and design patterns.
Implemented basic REST endpoints in Java/Spring Boot and Node.js/Express under the direction of senior engineers.
Wrote SQL queries for reporting tasks, simple data fixes, and validation jobs - building a solid foundation in relational database work.
Added unit tests and kept API documentation current to support QA and smoother cross-team releases.
Resolved bugs and delivered minor product enhancements based on QA tickets, meeting sprint commitments consistently.
