Production issues were reaching support that required backend-level diagnosis, not just surface-level troubleshooting. Escalations needed fast, accurate resolution with no margin for guesswork.

Collaborated directly with internal engineering teams to diagnose and resolve backend-escalated issues. Leveraged API diagnostics, PostgreSQL querying, and log analysis to trace root causes and deliver fixes, managing resolution workflows through Zendesk and Jira.

A growing fintech with multiple live products and mounting backend debt: a CRM that didn't exist yet, an admin dashboard so slow it was nearly unusable, manual customer service eating up team bandwidth, and no internal email infrastructure.

• PayBox360 CRM: Engineered the full lead management pipeline: creating leads, building pipelines, managing stages, and a round-robin scheduling system integrating Zoom, Google Calendar, and Calendly APIs so sales officers never missed a booked meeting.
• In-house Email Infrastructure — Designed and built an internal email system from scratch: sending, retrieving, saving, deleting, and drafts — all exposed via clean REST endpoints.
• Wisewinn Dashboard Optimisation — The admin dashboard was loading in minutes when it should have loaded in milliseconds. I profiled the bottleneck, implemented database indexing, layered Redis caching on hot queries, and offloaded heavy computation to Celery. Load time dropped by 99%.
• Loan Default Tracking: Integrated third-party APIs to automatically detect and flag borrowers defaulting on Seeds & Pennies loan repayments, eliminating manual monitoring entirely.
• Customer Service Automation — Built backend endpoints connecting n8n workflow automations with Freshchat, streamlining the entire customer service operation.

Build an AI-powered slide deck generator from zero with a cross-functional team to lead, no existing codebase, and a tight timeline. The goal: turn plain text into structured, presentation-ready slides using NLP.

• AI Slide Generation Engine: Used NLTK to process raw text input and automatically generate structured slide decks.
• Authentication System — Built user sign-up, login, and Google OAuth flows from the ground up.
• Full API Layer — Designed and built all REST endpoints powering the application.
• Infrastructure Setup: Configured PostgreSQL, deployed to Vercel (frontend) and Railway (backend server).
• Team Leadership: Managed progress across designers, frontend, and backend engineers by keeping momentum and morale high through the entire project timeline.
